Accident occurred Saturday, December 31, 2016 in Vienna, IL
Aircraft: PIPER PA 28R-200, registration: N2806R
Injuries: 4 Fatal.

This is preliminary information, subject to change, and may contain errors. Any errors in this report will be corrected when the final report has been completed. NTSB investigators either traveled in support of this investigation or conducted a significant amount of investigative work without any travel, and used data obtained from various sources to prepare this aircraft accident report.

On December 31, 2016, about 1745 central standard time, a Piper PA 28R-200 airplane, N2806R, impacted trees and terrain near Vienna, Illinois. The pilot and three passengers were fatally injured. The airplane was destroyed during the impact. The airplane was registered to and operated by the pilot as a 14 Code of Federal Regulations Part 91 personal flight. Marginal visual meteorological conditions were reported near the accident site about the time of the accident, and the flight was not operated on a flight plan. The flight originated from the Pella Municipal Airport, near Pella, Iowa at unknown and was destined for Nashville, Tennessee.

According to preliminary information, witnesses saw the airplane flying low and descend. A witness subsequently called 9-1-1 and a search was conducted by Johnson County Sheriff's personnel. The smell of fuel was present in the area identified by the caller. That smell led the Sheriff's personnel to the wreckage.

The 34-year-old pilot held a Federal Aviation Administration (FAA) commercial pilot certificate with a single engine land rating issued on June 30, 2016. The pilot held an FAA third-class medical certificate, dated May 12, 2016, with no limitations. Copies of the pilot's logbook showed his last recorded entry was dated July 24/26, 2016. The logbook showed the pilot's recorded flight time was 312.9 hours of total time, 18.9 hours of night flight time, 13.7 hours of simulated instrument flight time, and no flight time in actual instrument conditions.

N2806R, a 1969 model Piper PA 28R-200, Arrow, serial number 28R-35293, was a single-engine, propeller-driven, retractable landing gear, semi-monocoque design, four-seat, low wing airplane. The engine was a 200 horsepower Lycoming IO-360-C1C engine, with serial number L-15630-51A. The propeller was a constant speed, two-bladed, Hartzell HC-C2YK-1BF model, with serial number CH40395B. A review of copies of excerpts from the aircraft logbooks revealed an annual inspection was completed on June 6, 2016. The airframe logbook entry on that date indicated that the airplane had accumulated 6,297.3 hours of total time and its tachometer read 2,766.3 hours. The excerpts indicated that the most recent altimeter, static, and transponder inspection was performed on June 22, 2016, the engine tachometer read 2,771.2 hours, and the airplane had accumulated 6,302.2 hours of total time at that date.

At 1753, the recorded weather at the Barkley Regional Airport (PAH), near Paducah, Kentucky, located about 18 nautical miles and 174 degrees from the accident site, was: Wind 220 degrees at 4 knots; visibility 10 statute miles; sky condition overcast clouds at 700 feet; temperature 6 degrees C; dew point 4 degrees C; altimeter 29.91 inches of mercury.

According to preliminary information from FAA inspectors, there was no record of N2806R contacting the tower at PAH, or the tower at the Williamson County Regional Airport, near Marion, Illinois, or the air traffic control center.

The main wreckage came to rest about 43 degrees and .46 miles from the intersection of Crossroads Road and Old Metropolis Road. Broken branches, branches with linear separations, the upper portion of the rudder, a ground scar, and the engine were found in a debris path. The heading from the first found tree with broken branches to the main wreckage was 35 degrees magnetic. The upper portion of the rudder was found about 75 feet from that first tree with broken branches, the ground scar was about 90 feet from that tree, the engine and nose landing gear was about 105 feet from that tree, and the main wreckage was about 150 feet from that tree. The propeller hub and blades remained attached to its crankshaft. One propeller exhibited "S" shaped bending. There was no sign of fire in the debris path or wreckage.

The stabilator remained attached to its fuselage mounts and the stabilator's travel stops did not exhibit any witness marks consistent with repeated contact. The right side of the stabilator exhibited leading edge semicircular aft deformation consistent with the size of tree branches and skin separation at the inboard manufactured splice. Control continuity was established from the stabilator balance weight to the cockpit area. The stabilator trim tab remained attached to the stabilator with impact damage noted to the right hand outboard section. The stabilator trim rod remained attached to the trim tab as well as the trim barrel assembly. The stabilator trim was found to be in a full nose up trim setting. The stabilator trim wheel was found separated from its fuselage mount. Stabilator trim continuity was established from the separated trim wheel to the trim barrel. The vertical stabilizer remained attached to its forward fuselage mount. The rudder was separated from the vertical stabilizer. The rudder torque tube remained attached to its fuselage mount but was separated from the remainder of the rudder assembly. Control continuity was established from the separated rudder pedal assembly to the rudder torque tube. The rudder travel stops remained intact and exhibited no signs of repeated contact.

The fuselage was fragmented from the wing spar box forward to the engine. The rear bench seat remained, in part, attached to the fuselage. The left rear and right rear seat belts remained attached to their mounts and were found to be functional when field tested. No shoulder harnesses were installed in the rear seats. The pilot lap belt and shoulder harness was noted. The pilot's inboard seat belt mount was found separated from the fuselage at its fasteners. The copilot's lap belt and shoulder harness assembly were not located within the wreckage. Field test of the pilot's lap and shoulder harness found them to be functional. The pilot and copilot seats were found separated from their fuselage mounts and they exhibited downward deformation.

The instrument panel was destroyed. The attitude indicator and horizontal situation indication gyros were removed and disassembled. Disassembly revealed both gyros had witness marks consistent with a rotating gyro rubbing on its housing.
The engine control quadrant was found separated and it exhibited crush deformation. The landing gear selector was found in the "Down" position. The firewall and fuselage bottom skin was found was found separated from the remainder of the fuselage. The ruder pedal assembly was found separated from its mounts. The control yoke's "T" bar assembly was found fragmented and separated from its mounts as well as the control yoke shafts were found separated from "T" bar assembly. The fuel selector was found damaged and separated from its mounts. The fuel selector valve was noted to be in an "off" position.

About 78 inches of the inboard left wing remained attached to the fuselage spar box and rearward deformation damage was noted to the leading edge of the inboard section of the wing. The left wing's fuel tank was deformed and breached. Its pickup screen was found clear of obstructions. The remainder of the separated wing was found in the area of the main wreckage and its aileron remained, in part, attached to the wing. The aileron balance weight was found separated and the weight was not located within the wreckage. The flap was found in the "Up" position. It was fragmented and remained, in part, attached to its wing mounts. The aileron's bellcrank was separated from its mounts and the bellcrank remained attached to the aileron via the push pull tube. The bellcrank stops did not exhibit any signs of repeated contact. Control continuity was established from the aileron to the "T" bar chain and to the overload separation balance cable in the center fuselage area. The pitot head remained attached to the separated section of wing and its static hole was clear of debris. However, the pitot hole was found obstructed by a media consistent with wood.

The right wing was found separated from the fuselage at the spar box and was also separated at the flap and aileron seam. The flap remained attached to its wing and was found in the "Up" position. The aileron remained attached to its mounts and its aileron balance weight remained attached to the aileron. The right fuel tank was found deformed and breached. Its fuel tank pickup screen was found clear of obstructions. The entire length of the right wing exhibited rearward deformation. The aileron bellcrank and stops were found separated from their mounts and the stops did not exhibit any repeat contact witness marks. The aileron cables remained attached to the bellcrank but were found to be separated in overload by the wing root area. Aileron control continuity was established from the wing root to the bellcrank. The aileron push pull tube was separated from the bellcrank. The aileron balance cable was separated 50 inches from the cable's turnbuckle and the cable separation exhibited a broom straw appearance. The aileron drive cable was separated 12 inches from the cable's turnbuckle and the cable separation exhibited a broom straw appearance.

The engine had all of its accessories separated from the accessory gear box. All pushrods were found with bending deformation. The engine's sparkplugs were removed. The top spark plug for cylinder no. 1, no. 2, no. 4, and the bottom spark plug on cylinder no. 3 exhibited a normal condition. The remaining sparkplugs exhibited impact damage. The engine crankshaft was rotated by rotating the propeller by hand. Drivetrain continuity was observed when the accessory gearbox gears and valve train components moved in correlation to the crankshaft movement. A borescope examination of the cylinders did not reveal any anomalies. Each cylinder produced a thumb compression as the crankshaft was rotated. Both of the magnetos exhibited impact damage and could not be tested. The oil pickup screen condition was found clear and free of debris. The fuel servo was separated from its intake and its fuel screen was clear and free of debris. The fuel flow divider was disassembled. No anomalies were observed. The internal cavity of the divider had a glossy appearance and smell consistent with aviation gasoline. The separated engine driven was damaged and could not be tested. The electric fuel pump did not pump a fluid when electrical power was applied. Disassembly of the pump revealed its magnet had fragmented. The pump's shaft was rotated through an attached drill and the pump pumped a fluid when the drill was activated.

The propeller hub and blades were removed from the engine and disassembled. The disassembly examination revealed that oil was found in the forward portion of the propeller dome. Both blades had their control knobs separated from their blade butts. Witness marks revealed the blades were in a cruise flight pitch range. No preimpact anomalies were observed during the disassembly examination.

The Jackson County Coroner's Office was asked to perform an autopsy on the pilot and take toxicological samples.

A cell phone was found in the wreckage it is being sent to the National Transportation Safety Board Recorder Laboratory to see if it contains data in reference to the flight.

Curt Terpstra

PELLA, Iowa (KCRG-TV9) -- Two families filed a lawsuit two months after a New Year’s Eve plane crash killed four Iowans flying out of Pella. 

The families of a brother and sister who were on board are suing the estate of the pilot.

The suit, filed late Wednesday afternoon Marion County District Court, claims that the pilot, 34-year-old Curt Terpstra, was not qualified to be flying in stormy weather and should have never left the ground.

The Piper PA28R-200 left Pella for Nashville but made a stop in Missouri and slammed into the ground in southern Illinois. All four people on board were killed: Krista Green, 37, siblings Jordan Linder, 35 and Jasmine Linder, 26, and the pilot.

Attorney George LaMarca filed suit on behalf of the Linder families, claiming that Terpstra was not instrument certified and should not have been flying in bad weather at night.

KCCI obtained a copy of the National Transportation Safety Board Accident report showing that Terpstra had not flown for months. His last recorded entry was dated July July 24-26, 2016.

The logbook showed that the pilot had logged only 18.9 hours of night flight time and no flight time in instrument conditions.

“Marginal visual meteorological conditions were reported near the accident site with overcast clouds at 700 feet,” the accident report says.

A source and Terpstra never filed a flight plan and did not have an official Federal Aviation Administration weather briefing before taking off.

The manager of the Pella Airport was contacted on Wednesday, but he had no comment.

A Pella man was one of four people killed in a plane crash Saturday night near Vienna, Illinois, officials reported.

The plane that crashed was identified through an FAA database that tracks the ownership of airplanes by county. According to the database and family members, the plane was owned by North Mahaska High School graduate Curt Terpstra, of Pella, who co-owned Terpstra Masonry in Pella with his brother, Chip.

The crash occurred at about 5:30 p.m. Dec. 31. No cause has yet been identified.

Michael and Marcia Terpstra identified one of the victims as their son, Curt Terpstra. The other passengers involved in the crash have been identified by the Johnson County, Illinois Coroner as Jordan Linder, 35 of Iowa, Jasmine Linder, 26 of Iowa and Krista Green, 37 of Iowa. 

"[I'm in] Utter shock," Michael Terpstra said of the accident. "I don't know what happened. They were headed to Nashville. "

Michael Terpstra and another family member said a passenger on the plane took photos and sent them via a social media site to friends and relatives.

"They had taken some photos earlier [in the flight], there were clouds and it was clear," he said.

Marcia Terpstra said at one point, the passenger sent a photo of the storm outside the plane.

"All the sudden they were sending pictures of a storm they were in," Marcia Terpstra said.

The Chronicle was able to contact two other members of the Terpstra family through social media messages, but few details on the crash were available at 9:02 p.m., Jan. 2.

Michael Terpstra said his son, Curt, was an excellent pilot and had recently started an agricultural aviation business.

The plane crash happened in a wooded area outside of Vienna, Illinois, confirmed Eric Weiss, an official with the National Transportation Safety Guard.

The plane was a single-engine Piper model PA-28R-200, Weiss said. The other passengers in the plane at the time of the accident have not been officially identified.

Investigators with the National Transportation Safety Board began taking a closer look into the accident at about 9 a.m., Jan. 1, Weiss said.

According to the Associated Press there were two men and two women victims.


A small plane that crashed in Illinois Saturday, killing four people, was owned by a Pella man, federal records show.

The plane, a single-engine Piper, crashed in the woods near the southern Illinois town of Vienna Saturday night.

Eric Weiss, a spokesman for the National Transportation Safety Board, said Monday that other officials gave his agency a tail number corresponding to a plane owned by a Pella man. Online federal records show the plane was a Piper PA28R-200, built in 1969.

Illinois authorities had not identified the four victims by Sunday afternoon. The Des Moines Register did not immediately publish the owner’s name, because it was unable to confirm if he was aboard and authorities said they still were trying to notify victims' relatives about the deaths. The Associated Press reported the victims were two men and two women.

Weiss said investigators hope to have the wreckage moved into an enclosed facility by Tuesday, so they could take a closer look into what caused the crash.

The crash happened in a heavily wooded area outside of Vienna, which is between St. Louis, Mo., and Nashville, Tenn. A nearby resident, David Oliver, told WPSD-TV that the plane flew low near his house.

"Ten or 15 seconds later, we heard the crash," he said. Oliver said it took rescuers a substantial amount of time to find the wreck in the darkened woods.


WSIL -- UPDATE: On Sunday, federal investigators arrived to the scene of plane crash that killed four people in Johnson County.

The crash happened around 5:45 p.m. in a wooded area southeast of Vienna.

Investigators will examine the wreckage to determine what caused the plane to crash.

ORIGINAL STORY (Saturday, Dec. 31):

Four people were killed after a small plane crashed in a wooded area southeast of Vienna in Johnson County.

The Johnson County coroner said the victims are two adult men and two adult women.

Their names have not been released.

The Illinois state police said the victims are from Iowa.

The FAA identified the plane as a Piper PA28 and say it crashed under unknown circumstances.

Residents said they saw the plane crash into the wooded area near Crossroads Road around 5:45 p.m. on Saturday.

Initial reports said locals saw a plane flying low, then heard something crashing into the woods, followed by a "big fireball."

Larry Greer, a local resident, spoke to a couple who he said saw the plane right before it crashed.

"They didn't know if it was a plane or a helicopter at first, it was so loud and so low," said Greer. "They thought it was going to take the roof of their house off. They said they looked outside and they could see the plane and they could see fire coming from the plane."

Authorities used drones and UTVs to find the plane crash site.

Crews will be back at the crash site on Sunday, along with investigators from the Federal Aviation Administration and the National Transportation Safety Board.

Repairing a 1945 seaplane is a labor of love for Duluth volunteers

It was a plane designed to search for and track Japanese fleets in World War II. After the war, it was used as a water bomber to fight fires all over the world. It has been described as one of the most rugged and versatile aircraft in U.S. history.

But a powerful gust of wind in South St. Paul put an end to the flying days of one particular Consolidated PBY-6A Catalina, now being restored by the Duluth-based Lake Superior Squadron 101 of the Commemorative Air Force, which hopes to get its 1945 seaplane airborne again by 2020.

The all-volunteer group, made up of about 50 members, works out of an abandoned U.S. Air Force hangar on Monday evenings. About half its members live in the area and half of those regularly work on the plane, which has proved to be as pesky as any 72-year-old patient.

They're working on the 104-foot wing right now, inspecting the surface for defects. They've found quite a few.

"For every one we fix, we find three more," said the unit's leader, Kevin Parks.

The group has been getting assistance from volunteers working nearby at AAR Corp. Students at Lake Superior College's School of Aviation also have pledged to help with a corrosion inspection of the entire aircraft.

The Catalina being restored in Duluth never made it overseas in wartime.

Built in March 1945, it was in and out of storage with the military before it was purchased by a private company in Manitoba, Canada, which converted it into a water bomber to fight forest fires. It went back into storage and was later bought by the government of France before coming back to the U.S. and being put in storage yet again.

The Commemorative Air Force, a Texas-based nonprofit that restores and preserves World War II-era combat aircraft, acquired the plane in February 1994. For several years, it was housed and flown out of the group's hangar in South St. Paul.

But in May 1998, high winds from a storm flipped the aircraft onto its back and destroyed the wing and part of its tail, Parks said.

In fall 2009, the Lake Superior Squadron 101 took a wing from another PBY and mated it to the hull.

The restoration, which is ongoing, will continue to be time-consuming and expensive.

Parks said the cost to complete the project could run as high as $200,000. Besides the wing work, both engines will need to be overhauled at an estimated cost of $55,000 each.

The National Naval Aviation Museum describes the Catalina as one of the most recognized planes in the world, with its parasol-mounted wing and retractable stabilizing floats that fold upward to become wingtips in flight.

Between 1936 and 1945, 4,000 Catalinas were built and the planes earned a reputation as a workhorse of naval aviation. It was involved in almost every major operation in World War II and figured significantly in defeating the U-boat menace in the Atlantic. It also was used extensively in civilian service.

The U.S. Forest Service retired its last PBY in the early 1980s. It is estimated that 30 of the planes are still airworthy, according to the website Warbird Alley. If all goes well, one more will be back in the air in about three years.

"The original plan was to fly it in 2013, but you run into stuff and you've got to fix it," Parks said. "It's all a labor of love, though."

The Commemorative Air Force's Lake Superior Squadron 101 has a museum in Duluth at 4931 Airport Road. The museum is free and open to the public on Wednesdays and Saturdays from 10 a.m. to 3 p.m.

Bell 206L LongRanger, N16760, Smoky Mountain Helicopters: Fatal accident occurred April 04, 2016 in Pigeon Forge, Sevier County, Tennessee

Family files lawsuit claiming negligence in Pigeon Forge scenic helicopter crash

Johna Morvant
SEVIERVILLE (WATE) – Family of Johna Morvant, a woman killed in a scenic helicopter crash in Pigeon Forge back in April, has filed a federal lawsuit against the owner of Great Smoky Mountain Helicopters, Inc., Bobby Riggs.

Keith Morvant, Johna’s husband, and mother Lynne Frederick, Johna’s mother are suing Bobby Riggs claiming negligence and gross negligence.

WATE 6 On Your Side obtained the federal court document which says Morvant and Frederick claim “Riggs had a duty to exercise reasonable care as an owner of the helicopter when operating, servicing, inspecting and/or certifying same as airworthy. The helicopter crash and subsequent death were the direct and proximate result of the negligent acts and omissions and conduct of Riggs and his agents.”

The document further claims the helicopter wasn’t properly maintained and serviced and that adequate pre-flight inspection of the helicopter wasn’t preformed.

The National Transportation Safety Board, which is investigating the crash, said five people were killed including the pilot Jason Dahl, 38, Kodak resident Johna Morvant, 49, her two children Parker Rasmussen, 18, and Peyton Rasmussen, 22, as well as Peyton Rasmussen’s boyfriend, Michael Mastalez, 21.

National Transportation Safety Board - Aviation Accident Preliminary Report: 

FAA Flight Standards District Office:  FAA Nashville FSDO-19

NTSB Identification: ERA16FA144

14 CFR Part 91: General Aviation
Accident occurred Monday, April 04, 2016 in Pigeon Forge, TN
Aircraft: BELL 206, registration: N16760
Injuries: 5 Fatal.

This is preliminary information, subject to chang
e, and may contain errors. Any errors in this report will be corrected when the final report has been completed. NTSB investigators either traveled in support of this investigation or conducted a significant amount of investigative work without any travel, and used data obtained from various sources to prepare this aircraft accident report.

On April 4, 2016, about 1610 eastern daylight time, a Bell 206L, N16760, was destroyed when it impacted terrain while maneuvering in Pigeon Forge, Tennessee. The helicopter was operated by Great Smoky Mountain Helicopters, Inc., doing business as, Smoky Mountain Helicopters. The commercial pilot and four passengers were fatally injured. Visual meteorological conditions prevailed and no flight plan had been filed for the flight that departed Sixty Six Heliport (6TN3), Sevierville, Tennessee. The local air tour flight was conducted under the provisions of Title 14 Code of Federal Regulations Part 91.

According to the operator, the helicopter had been purchased in 1986 for air tour/sight-seeing purposes. At the time of the accident, the operator owned two helicopters, a Bell 206B that was based in Cherokee, North Carolina, and the accident helicopter, which was based at 6TN3.

A company pilot reported that he flew the helicopter an estimated 10 flights on the morning of the accident, and before the accident pilot began flying sometime between 1300 and 1400. The accident pilot performed 4 flights in the helicopter and then shut it down while waiting for additional customers. The accident pilot subsequently restarted the helicopter, and completed a 4 minute flight before departing on the accident flight, which was scheduled to last between 7 and 8 minutes. He further stated that a check of the fuel level prior to departure revealed it was "just below the 6-inch line," which he estimated corresponded to about 300 pounds of fuel on board.

Another helicopter tour company pilot operating in the area about the time of the accident reported that he did not hear any distress calls. He further stated that he recalled the accident pilot made a normal landmark position report over "wonderworks."

A witness who lived near the accident site reported that he was outside when he observed the helicopter flying low in a descent, and it "didn't sound right." He further described the sound as if "the engine was wound tight" and it "lost the rotor sound." He then heard the engine go silent, "as if the pilot cut the power," which was followed by sounds associated with impact. Another witness reported hearing the impact and observed the accident site engulfed in fire.

The helicopter initially impacted trees near the top of a ridge that was about 1,100 feet mean sea level (msl). The helicopter came to rest in a wooded area near the bottom of the ridge, on its left side, on a heading of about 340 degrees magnetic. Two large, freshly broken trees were located about 100 feet south of the main wreckage, which was mostly consumed by a postcrash fire. In addition, the entire area surrounding the main wreckage was charred.

All major structural components of the helicopter were located at the accident site. One of the two main rotor blades was separated, and located about 20 feet northwest of the main wreckage. The leading edges of both main rotor blades did not exhibit significant impact damage. Manual rotation of the main rotor blade that remained attached to the main rotor hub resulted in rotation of the main rotor mast, the engine-to-transmission drive shaft, the engine's No. 4 turbine wheel, the tail rotor drive output, and confirmed free-wheel functionality. The tail rotor drive shaft was fractured in multiple locations. The flexible couplings between the drive shaft flanges were intact and did not display evidence of fractures or deformation consistent with power at impact. The tail rotor gearbox was separated from the tail boom and located about 30 feet southeast of the main wreckage. Manual rotation of the tail rotor blades resulted in rotation of the gearbox input. The splines at the tail rotor gearbox did not exhibit evidence of fractures or smearing. All three flight control servo control linkages were fractured at multiple locations; however, the linkages remained attached to their respective input and output ends. There was no evidence of damage to the engine's first stage compressor section, or fourth stage turbine wheel.

The engine and airframe were recovered from the accident site and retained for further examination.

Initial review of maintenance records revealed that at the time of the accident, the helicopter had been operated for about 40 hours since its most recent 100 hour and annual inspections, which were performed on March 4, 2016. In addition, the helicopter had been operated for about 22,560 total hours.

The pilot reported 550 hours of total flight experience on his most recent application for a Federal Aviation Administration second-class medical certificate, which was issued on April 21, 2015. According to an initial review of the pilot's logbook, as of March 25, 2016, he had logged about 1,300 hours of total flight experience, which included about 870 hours in Bell 206 series helicopters.

A weather observation taken at airport located about 3 miles northeast of the accident site, about the time of the accident, reported: winds from 220 degrees, at 10 knots, 10 statute miles visibility, clear skies, temperature 24 degrees Celsius (C), dew point 2 degrees C, and an altimeter setting of 29.93 inches of mercury.
