Aviation Accident Final Report - National Transportation Safety Board: https://app.ntsb.gov/pdf
Analysis
The airplane was equipped with an air sampling system used to collect air samples at various altitudes. The accident occurred when the pilot was returning to the airport after taking air samples at various altitudes over oil fields. As he was being vectored for an instrument approach, the airplane overshot the runway's extended centerline. The pilot then reported that he had a fire on board. The airplane lost altitude rapidly, and radar contact was lost. Examination of the accident site indicated that the airplane struck the ground at high velocity and a low impact angle.
One piece of the airplane's shattered Plexiglas windshield exhibited soot streaking on its exterior surface. This soot streaking did not extend onto the piece's fracture surface, indicative of the smoke source being upstream of the windshield and the smoke exposure occurring before windshield breakup at impact.
Both nose baggage compartment doors were found about 2 miles south of the main wreckage, which indicative that they came off at nearly the same time and most likely before the pilot's distress call. Although there was no soot deposits, thermal damage, or deformation to the doors consistent with a "high energy explosion," the separation of the luggage compartment doors could have occurred due to an overpressure caused by the ignition of a fuel air mixture within the nose portion of the airplane. The ignition of fuel air mixtures can create overpressure events when they occur in confinement. An overpressure in the nose baggage compartment may have stretched the airframe enough to allow the doors to push open without deforming the latches. If it was a lean fuel air mixture, it would likely leave no soot residue.
Post-accident examination revealed no evidence that the air sampling system, which was strapped to the seat tracks behind the copilot's seat, was the cause of the fire. The combustion heater, which was mounted in the right front section of the nose baggage compartment, bore no evidence of fuel leakage, but a fuel fitting was found loose.
Probable Cause and Findings
The National Transportation Safety Board determines the probable cause(s) of this accident to be:
The loose fuel fitting on the combustion heater that leaked a lean fuel-air mixture into the nose baggage compartment. The mixture was most likely ignited by the combustion heater, blowing off the nose baggage compartment doors and starting an in-flight fire.

The airplane, serial number 340-0251, was manufactured in 1973 by the Cessna Aircraft Company, Wichita Kansas. It was powered by two Continental TSIO-520-JB engines (serial numbers 275386-R, left; 183304R, right), driving two Hartzell 3-blade, all-metal, constant speed propellers (model number 3AF32C87-N; serial number 767923, left; 786086, right). Both engines had a 1,400-hour time-between-overhaul limitation.
The last annual inspection of the airplane occurred on July 27, 2016, at a total time of 7,012.6 hours. The last 100-hour inspections of both engines and propellers were also on July 27, 2016. At that time, the left and right engines had accrued 6,676.4 hours and 7,134.6 hours total time, respectively. The left engine had been overhauled on March 25, 2014, and the right engine had been overhauled on September 25, 2012.
The airplane was last certified for flight in instrument meteorological conditions on August 2, 2016.
The airplane was equipped with a Stewart Warner combustion heater, sometimes referred to as a Janitrol heater, that was used to provide cabin heat. The heater was mounted in the right front section of the nose baggage compartment.
The airplane carried a NOAA air sampling system manufactured by High Precision Devices, which was stored in two plastic boxes. One box was filled with glass jars for holding air samples. The remains of this box were found melted to the top forward fuselage. The second box contained the compressor package, which consisted of a rechargeable battery pack, two compressors, circuit boards wiring, and air tubing. The boxes were strapped to the seat tracks behind the copilot's seat.
NOAA representatives reported that the system had been in use for 12 years at 14 different locations. They said that there had never been any reports of fire with the air sampling system. They pointed out that the system does not operate all the time, only when the pilot pushes a button on the remote control attached to the glare shield. A typical mission would be for the airplane to climb to 25,000 feet and the pilot would then activate the system. The system would operate for 2 to 2.5 minutes taking air samples, and then shut off automatically when the sample collection was complete. The pilot would descend to the next sampling altitude and repeat the process.

Total Injuries: 1 Fatal
Latitude, Longitude: 46.920556, -96.815833 (est)
The accident site was in an open field about 10 miles south of FAR at an estimated elevation of 900 feet msl. It was bordered by trees and a ravine to the east. The location of the accident site was 46°43.727' north latitude, and 96°49.686' west longitude. All components of the airplane were identified at the accident site except for the nose baggage compartment doors, which were found about 2 miles south of the main wreckage.
The wreckage path at the accident site was on a magnetic heading of 197° degrees. Ground scars and impact damage were consistent with the airplane striking the ground at high velocity with a low angle of impact and in a left-wing-slightly-low and nose-up attitude. The first evidence of ground contact was multiple propeller slash marks consistent with the left propeller contacting the ground, which was followed by ground scars consistent with the fuselage contacting the ground. Continuing along the wreckage path, there were multiple slash marks consistent with the right propeller contacting the ground. Both upper engine cowlings, the propellers, and the upper nose skin separated from the airplane. Ground scars were consistent with the airplane becoming airborne for a short distance before sliding down an embankment and impacting trees in a wooded area along a creek bed to the east. The right wing, from the engine nacelle outboard, and the empennage separated as the airplane travelled forward. No soot or molten metal was observed on the separated empennage. The fuselage came to rest inverted about 550 feet from the initial point of impact.
The primary flight control cables were connected to their associated flight control surfaces and cockpit controls. All the cables exhibited either tension overload separations or had been cut by first responders. The mid-fuselage aileron bellcrank and the flap motor were consumed by fire. The flap sprockets were engaged in the right flap chain, and the chain was in a non-standard position. The left flap chain had separated from the flap drive motor. Both fuel selector handles were consumed by fire. The left fuel selector valve was in an undetermined position. The right fuel selector valve was in the "OFF" position. No smoke streaking or heat damage was noted at the heater connection in the nose baggage compartment.
The combustion heater was found on the ground next to the cabin area. The heater was intact, impact-damaged, sooted, and showed no signs of explosion. All flight instruments and switches were either damaged or consumed by the post-impact fire. The main circuit breaker bus bars did not exhibit evidence of hot spots. The engine fuel and oil pressure lines did not exhibit evidence of pre-impact fire.
Medical And Pathological Information
The University of North Dakota's School of Medicine and Health Sciences, Department of Pathology, Forensic and Autopsy Service, Grand Forks, North Dakota, performed an autopsy on the pilot. According to their report, death was attributed to "multiple injuries." Their toxicological analysis of blood obtained at autopsy was negative for ethanol, drugs, and cyanide. A small amount of carbon monoxide (6% saturation} was detected in blood.
The Federal Aviation Administration's (FAA) Bioaeronautical Sciences Research Laboratory, Oklahoma City, Oklahoma, also performed a toxicological analysis. According to their report, no carbon monoxide, cyanide, ethanol, or drugs were detected in heart blood. No tests were conducted for the presence of halon or halotron.
Tests And Research
The wreckage was transported to a Weather Modification hangar in FAR, where it was laid out and re-examined.
On December 13, 2017, the compressor package from the airplane's NOAA air sampling system was examined at the National Transportation Safety Board's (NTSB) Materials Laboratory in Washington, DC. The examination determined that all smoke and heat damage had originated externally. There was no evidence to indicate the air sampling system was the cause of the inflight fire.
The Stewart Warner (Janitrol) combustion heater was also examined by NTSB's Materials Laboratory. The body of the heater exhibited thermal discoloration and soot staining, consistent with exposure to a fire environment. There was no evidence of fuel leaks in the combustion heater body or the air blower assembly. One fuel fitting on the combustion heater body was found to be loose.
Plexiglas windshield pieces and the nose baggage compartment doors were also examined. One piece of Plexiglas exhibited soot streak stains on the outside of the windshield that did not extend into the fracture surface, indicative of the smoke source being upstream of the windshield and occurring prior to the windshield breakup. The other Plexiglas pieces had no significant accumulation of soot or thermal damage and had about the same amount of particulate buildup, consistent with no prolonged exposure to a smoke-filled cockpit condition.
The nose baggage compartment doors did not exhibit any soot deposits, thermal damage, or deformation consistent with a "high energy explosion." The latches on one of the doors were not deformed.
Additional Information
According to Weather Modification, LLC, the airplane was equipped with two hand-held fire extinguishers mounted in the cabin: one was halon, the other was halotron. Both extinguishers held about 5.4 pounds of agent. One had been discharged, the other showed signs consistent with exploding. It is not known which extinguisher had been discharged and which one had exploded. According to Textron Aviation, the Cessna 340 has a pressurized volume of 250 cubic feet plus or minus 50 cubic feet.
According to FAA's Bioaeronautical Sciences Research Laboratory, "Halon does not displace oxygen in its use like [carbon dioxide] does. Low concentrations of halon (less than 8% concentration by volume) are required for any given fire. The result is plenty of air for pilots and passengers to breathe, even during a fire incident . . . very high concentrations . . . could affect the pilot."
According to FAA's William J. Hughes Technical Center's Fire Safety Group, "The inhalation of halon 1211 and/or halotron may have affected [the pilot], depending on how much of each agent was released prior to the crash. All halons and halon replacements are cardiotoxic (have the potential to induce a heart attack) at high concentrations. Halon 1211 and many halon replacements also have narcotic effects at even higher concentrations. The cadiotoxic concentration threshold is lower than the incapacitation concentration threshold. A total release of 5.4 pounds of agent significantly exceeds the recommended agent weight for [the] stated volume of 250 cubic feet plus or minus 50 feet."

With the onset of a new year, it has become an obligatory ritual for every jaded traveler or adventurer to try something new or visit a unique and remote destination, away from the madding crowd of commercial tourist zones.
Those who have the moolah and the grit to take their passion to greater heights, quite literally, can either fly a private plane, own one or ride one, at the very least.
Taking to the sky used to be a pie in the sky just a few decades ago, with the prohibitive costs involved of pilot schooling. Well, not anymore with FoilaFly, which aims to revolutionize air travel and usher in a new era in personal transportation.
The official distributor and service center of Cirrus Aircraft in the country, it is much like a one-stop shop for aviation aficionados who once dreamt of rekindling their childhood fascination for flying.
“We are committed to the future of aviation through smart, safety, ease of operation and, most important, continuous innovation. Our aim is to bring flying closer to bigger spectrum of the target market. This is a lifestyle and business-oriented flying club,” Cirrus brand ambassador and FoilaFly CEO Lester Codog enthused.
The firm has partnered with Cirrus Aircraft, a trusted global brand in producing all-composite personal aircraft that incorporates advanced electronic and standard safety technologies.
The firm’s standard planes are single-engine four-seater Cirrus SR20s and SR22s, which are equipped with safety features like Cirrus Perspective by Garmin avionics and the Cirrus Airframe Parachute System, the only one of its kind among the current crop of aircraft that will enable it to land even under an extreme emergency.
Surprisingly enough, they can be had for just about the cost of a luxury sports car.
These sleek, fully automated aircraft are capable of short take-offs and landings even in unpaved airstrips, which gives travelers access to remote destinations not serviced by commercial airlines.
This flexibility enables pilots and passengers opt for the more exciting “air odyssey,” where they can hop around the country’s airports that are gateways to popular and up-and-coming destinations without passing through the congested airports.
Its panoramic interiors also enable passengers to admire the scenic spots from above and take Instagram-worthy photos.
Codog said the firm has formed the FoilaFly Aero Club, a unique group of pilots that provides aviation enthusiasts the privilege of enjoyable traveling across the archipelago through safe and inexpensive flying.
“As a member of the Philippines’s premier flying club, you can share with everyone your love and great enthusiasm of flying, and along with many, a colorful story of important events in your life and you have the freedom to fly as often as you want because you own the airplane,” he added.
The Aero Club conforms with Cirrus Standards and is undergoing certification by the Civil Aviation Authority of the Philippines to operate domestic flights. With facilities in Manila, Bulacan and Clark, FoilaFly is a Flight Training Center that provides aircraft rental/ownership for recreational pilots.
Every member undergoes flight training of up to 50 flying hours with the user-friendly Cirrus before being allowed to fly his own aircraft.
The Aero Club also offers services to those members who previously own Cirrus aircraft, such as tie-downs, 24-hour fuel availability and a guarded hangar.
FoilaFly is an expansion binge with the acquisition of more planes, including the Vision Jet, which raises the bar in aviation with its introduction of the “personal jet” lifestyle.
Down the road, the aviation firm intends of integrate air, land and sea vehicles, as well as board and lodging for a seamless tour package.
“When you become a Cirrus owner, you aren’t merely taking up a hobby, you are choosing a whole new lifestyle full of freedom, choices and responsibilities,” Codog concluded.
With all these advantages working to your favor, having your own plane will never be like flying on a wing and a prayer again.

TOWANDA, BRADFORD COUNTY (WBRE/WYOU) - Two hundred pounds of marijuana!
That is what state police say the found inside a plane that landed Wednesday night in the Northern Tier.
State police say two men were flying from California to Boston when they made a stop at the Bradford County Airport near Towanda.
That is where federal investigators caught up with them.
It is not unusual for people in the Towanda area to see planes landing at the Bradford County Airport but state police say what was found inside one plane Wednesday night was unusual, 200 pounds of marijuana.
"That's unusual! That's unusual! I think 200 (pounds) is more than enough for anybody to sell!" Susan Hadlock of Sayre said.
Matthew Roesner and Paul Riggie are now behind bars on drug charges.
Investigators say Roesner was flying the plane.
He told investigators that Riggie paid him $10,000 to fly across the country.
Roesner is a commercial airline pilot for Compass Airlines.
"There's his job, you know, his livelihood other than his second livelihood with the marijuana!" Michelle Miller of Herrickville said.
Customs and Border Protection agents started tracking the suspect's plane as it flew across the country.
Investigators say the plane didn't provide its travel itinerary and flew at an altitude inconsistent with federal standards.
"With all of the technology they have today they can do just about anything!" Frank Mucerino of Monroeton said.
Officials at the Bradford County Airport declined to comment on the situation. They would also not say where the suspect's plane currently is located.
In addition to the 200 pounds of marijuana, investigators say they also found cash and a .40-caliber pistol inside the plane.
Exactly why they stopped in Bradford County has not been disclosed but local residents say they're glad they were caught.
"They don't tolerate it too much around here!" Mucerino said.
Federal agents say Paul Riggie has a prior criminal history for selling marijuana and resisting arrest.
Both men are jailed tonight in lieu of $500,000 bail in Bradford County.

Flight Conducted Under: Part 91: General Aviation - Personal
Analysis
The private pilot was flying an experimental airplane at a low altitude along a river when the airplane struck a power line suspended 30 ft above the river, causing the airplane to cartwheel. The power line wrapped around the airplane, and the airplane descended straight down, impacting the ice-covered river.
A postaccident examination of the airplane showed that the fuselage forward of the instrument panel, the engine cowling, and the engine were bent upward about 30°. The forward fuel tank between the cabin and the engine had broken open, and the smell of fuel was apparent. The airplane's propeller showed indications that the engine was producing high power when the airplane struck the power line. Flight control continuity was confirmed. Examination of the engine and other airplane systems showed no preimpact anomalies. Thus, the accident likely occurred because the pilot did not see the power line suspended across the river while he was flying close to the river surface.
Probable Cause and Findings
The National Transportation Safety Board determines the probable cause(s) of this accident to be:
The pilot's failure to see and avoid the power line. Contributing to the accident was the pilot's intentional flight at low altitude.

Factual Information
On January 20, 2018, about 1233 central standard time, a Matheny Christavia Mk1 homebuilt airplane, N746LM, struck a power line and impacted on an ice-covered river during low-altitude flight near Grand Detour, Illinois. The pilot and pilot-rated passenger were seriously injured, and the airplane was substantially damaged. The airplane was owned and operated by the pilot as a 14 Code of Federal Regulations Part 91 personal flight. Day visual meteorological conditions prevailed, and a flight plan had not been filed for the local flight, which had departed from the Poplar Grove Airport (C77), Poplar Grove, Illinois.
Witnesses observed the airplane flying low over the Rock River between 1120 and the time of the accident. One witness who lived near Machesney Park, Illinois, saw the airplane flying 100 ft. above the river and within 400 to 500 ft. above houses. Another witness who lived along the back channel of the river near Grand Detour said the airplane went by her house so close that she could see the pilot in the airplane. She estimated the airplane was 15 ft. above the river. Moments later, the airplane struck a power line that ran from the river bank across to an island in the river. The airplane subsequently cartwheeled in the air wrapping the power line around it, and then dove straight down, impacting on the ice-covered river.
An examination of the airplane showed a power line wire wrapped around the leading and trailing edges of both wings at the wing roots, and around the aft cabin. The left aft cabin window was broken inward and showed wire marks on the Plexiglas. The right main landing gear was broken inward and under the airplane's cabin. Wire marks were observed on the tire and gear strut. The front windscreen was broken out and fragmented, and the forward fuselage at the instrument panel, the engine cowling, and the engine were bent upward 30°. The forward fuel tank between the cabin and the engine was broken open and the smell of AVGAS was prevalent. The airplane's wood propeller was broken aft and splintered circumferentially. The outboard 5 ft. of the airplane's left wing was broken aft and downward. Wire marks were observed along the top wing skin starting at the fracture and running aft and outboard toward the wing tip and wing trailing edge. Flight control continuity was confirmed. An examination of the engine and other airplane systems showed no preimpact anomalies.
According to Commonwealth Edison, the electricity provider to Grand Detour, the power line height above the river where the airplane came in contact with it was about 30 ft.
A NTSB Form 6120.1, Pilot/Operator Aircraft Accident/Incident Report form was sent to the pilot to complete. The pilot never returned the filled-out form, despite several attempts on the part of the NTSB and the Federal Aviation Administration to have him do so.

Injuries: 2 Serious
Flight Conducted Under: Part 91: General Aviation - Personal
On January 20, 2018, about 1233 central standard time, a Matheny Christavia Mk1 homebuilt airplane, N746LM, struck a power line and an ice-covered river during low-altitude flight near Grand Detour, Illinois. The pilot and pilot-rated passenger were seriously injured, and the airplane was substantially damaged. The airplane was owned and operated by the pilot as a 14 Code of Federal Regulations Part 91 personal flight. Day visual meteorological conditions prevailed, and a flight plan had not been filed for the local flight which had departed from the Chicago/Rockford International Airport (RFD) Rockford, Illinois.
The airplane was observed flying low along a back channel of the Rock River, south of Grand Detour. One witness who lived along the back channel said the airplane went by her house so close that she could see the pilot in the airplane. She estimated the airplane was 15 ft. above the river. Moments later, the airplane struck a power line that crossed the river. The airplane subsequently cartwheeled, and dove straight down, impacting on the ice-covered river.
An examination of the airplane showed a power line wire wrapped around both wings. The airplane's wood propeller was broken and splintered circumferentially. The forward fuel tank between the cabin and the engine was broken open. The airplane was retained for further examination.

GRAND DETOUR – A handful of local residents were outdoors taking advantage of the springlike weather Saturday afternoon when their chores were interrupted by a plane crash.
Illinois State Police responded to a call at about 12:50 p.m. that a small plane had landed or crashed in the Rock River near Grand Detour.
The pilot, David R. Manske, and his passenger, Jamie K. Nadowski, 60, both of Machesney Park, were taken to a hospital, but luckily escaped serious injury. No information on their flight plan was available Sunday.
Jim Ross was working in his garage just north of the crash site when he heard the plane fly over his home around 12:40 p.m.
“I was in the garage and I heard a plane flying by. Then there was a big noise – and silence,” Ross said. “Then a neighbor came by and said a plane was on the ice and to call 911. He had heard it too and drove over and saw it on the ice.”
Ross walked south a few yards where he saw the pilot exit the plane and walk around a bit.
Kelly Snyder, who lives just a house down from Ross, and almost directly across from where the plane came to rest, also heard a loud bang, but thought it was just a vehicle backfiring.
“I heard a pop, pop and I thought it was just a Jeep or truck backfiring. I went outside a few minutes later and started playing with our our dogs and tossing them balls down the hill,” Snyder said. “When I walked down our hill to get one of the balls I saw the plane and at first I was, ‘Oh no, a plane crashed,’ and my first thought was that if it started to sink it was pretty shallow there.
Snyder said she then saw the pilot.
“I yelled and asked if he was alright and he waved his arms," she said.
Snyder’s son Dax, 12, was inside his family’s house and also heard a “snapping” noise.
“I think that was when they hit the power wire,” he said. “It looked like the pilot was trying to get the lady out.”
Ross watched as emergency responders wearing rubber suits dragged a rubber raft out to the plane to pick up the pilot and his passenger.
The plane had become tangled in a power line during the crash and ComEd workers had to cut power to a nearby home while they helped fire personnel to untangle the power line from the plane.
After Manske and Nadowski were rescued, police and workers from Maggio Truck Center in Rockford were left with the task of figuring out how to get an 800-pound plane off the river.
Using two tow trucks and a Fox Lake Fire Protection District’s Quad 2 Ice and Water Rescue Airboat, responders attached a winch line to the plane and slowly pulled it to the west shore and eventually up Snyder’s boat launch driveway and onto a flatbed tow truck.
That process, watched by about 20 people, ended around 8 p.m.
“I’m just glad they’re going to be OK,” Kelly Snyder said.
Investigators are still trying to determine whether the plane was having mechanical issues or hitting the power line caused it to go down. The Federal Aviation Administration has been brought into the investigation.

OGLE COUNTY - UPDATE: (7:00 p.m.) Illinois State Police say a Christavia Mk I plane crashed in the Rock River at around 12:30 p.m. in Grand Detour, Ogle County after hitting a power line.
Two people were inside the Christavia Mk I. One of them was walking on the ice when emergency crews got there, but they told him to immediately get back inside until rescue crews could get to him.
"One of the victims was out of the Christavia Mk I but we had them get back into the plane due to the fact it was on the ice," said Dixon Rural Fire Chief Sid Aurand. "They were mobile, they were conscious, but we did go out, 6 members of our department took a Fortuna which is an inflatable boat, walked out across the ice and retrieved the two victims from the plane," he added.
The victims were taken to a local hospital. Their injuries are not considered serious. The Christavia Mk I received minor damage. Investigators are not sure if hitting the power line is what caused the crash, or if the Christavia Mk I was having other issues.
