On July 30, 2018, about 1044 eastern daylight time (EDT), a Piper PA-60-602P, Canadian registration C-GRRS, was destroyed when it impacted terrain while attempting to land at Greenville Airport (3B1), Greenville, Maine. The foreign-certificated pilot and two passengers were fatally injured. The airplane was registered to and operated by the pilot under Canadian Aviation Regulations as a recreational flight. Visual meteorological conditions prevailed at 3B1 at the time of the accident, and an instrument flight rules flight plan was filed for the flight, which departed Pembroke Airport (CYTA), Pembroke, Ontario, Canada, about 0905, and was destined for Charlottetown Airport (CYYG), Prince Edward Island (PEI), Canada.

According to the CYTA airport manager, the pilot had been a regular customer at the airport for several years. The pilot flew the accident airplane into CYTA 3 days before the accident and purchased 117 gallons of 100LL fuel. The airport manager, who personally fueled the airplane that day, said that he topped off the wing tanks first, followed by the center tank. He did not fuel the auxiliary tank. The manager said that each of the fuel caps felt tight and he made sure they were properly fitted back onto each tank. The airplane was then placed in a hangar until the morning of the accident.

A review of air traffic control communications revealed that, after departure, the airplane climbed and leveled off at 23,000 ft mean sea level (msl) and the pilot contacted the Boston Air Route Traffic Control Center at 1019:39. About 13 minutes later, the pilot told the controller, "...we're losing altitude trying to figure out what's going on." The controller then began to vector the airplane toward 3B1, which was about 17 miles southeast. At 1033, the controller asked the pilot, "...are you producing power right now or have you lost power." The pilot responded, "I think I've lost power..." The controller asked the pilot if he could make Greenville Airport, and the pilot responded, "Ah I think so."

The controller continued to vector the pilot to 3B1 and declared an emergency on his behalf. At 1040:41, the pilot reported that he had the airport in sight and was going to join the downwind leg of the traffic pattern for runway 14. Radar data indicated that the airplane was at an altitude of about 4,600 ft msl at this time. The airplane continued to descend as it turned onto the base and final legs of the traffic pattern for runway 14. At 1043:32, said the pilot transmitted, without a call sign, "I gotta turn around and ahh we're a little high obviously." About this time, the airplane was on a short final for runway 14 at an altitude of about 1,800 ft msl (about 400 ft above ground level). The airplane then entered a left turn to the northwest and was over the airport when radar contact was lost at 1043:48.

A witness was standing on the airport's apron near the terminal building between runway 14 and 21 when he first saw the airplane approaching the airport from the south. The witness said the airplane was "low." It flew over the center of the airport and made what appeared to be a left downwind entry for runway 21. There was no smoke trailing the airplane and the landing gear was retracted. The witness said both propellers were turning, but he could not tell how fast they were turning or if one was turning faster than the other. He was standing next to active construction equipment at the time, which prevented him from fully hearing the engines. When the airplane reached the approach end of runway 21, it began a "shallow" left turn. The nose of the airplane was "high" and the airplane was "going so slow." He said, "It was like it almost stopped in the air" before the left wing suddenly dropped and the airplane dove toward the ground and disappeared behind an embankment. The witness saw a debris cloud and knew that the airplane had crashed.

A second witness, who was a commercial pilot, was standing in front of a hangar on the southeast side of runway 3/21 when he saw the airplane approaching the airport from the west. Instead of landing on runway 14, the airplane continued to fly over the center of the airport. The witness said that the airplane flew directly over him as it made a left turn and flew parallel to runway 3/21. He stated that both propellers were turning, and the engines were producing power; however, he could not estimate an engine speed. He said the airplane was not gliding because it maintained its altitude. The witness could not recall if the landing gear or flaps were extended but recalled that the belly of the airplane was painted black. When the airplane approached the end of the runway, it began a "shallow" left turn and was flying "really slow." The bank angle continued to increase to a point where he could see the entire top of the airplane. The airplane then pitched up and appeared to momentarily "stop" before the left wing "stalled" and the nose pitched down toward the ground. The witness did not hear any increase in engine noise before the impact. He also said that he did not believe the pilot was trying to land on runway 21 because he was positioned "way too close" to the runway.

The airplane came to rest in field about 100 yards from the approach end of runway 21 on a magnetic heading of 220°. All major components of the airframe were accounted for at the site and there was no post-impact fire. The wreckage was contained to where it impacted the ground. The nose and forward fuselage area were compressed aft from impact; both engines were partially buried in the ground, and the empennage was compressed and twisted to the left. The tail section appeared undamaged and was twisted to the left. Both wings remained attached to the airframe at the wing root and sustained impact damage.

Both wing fuel tanks were breached, but the fuel finger screens in both tanks were absent of debris. The center fuel tank (bladder-type) was breached, and the auxiliary fuel tank remained in the airplane but was breached. According to first responders, about 20 gallons of fuel was recovered from the site. The vegetation forward of the wreckage displayed fuel blighting. The fuel selector handles were impact damaged and their position could not be determined. Continuity of the fuel system from the wings to the center fuel tank was established. The center sump was filled with 100LL fuel and the screen was absent of debris. The Nos. 1 and 4 fuel shutoff valves were in the "Open" position, and the Nos. 2 and 3 cross-feed valves were in the "Closed" position.

The left and right fuel boost pumps were located and the main fuel line to each pump was separated from impact. Fuel was observed draining from each pump. Each pump was tested on a 24-volt battery and both pumps were functional. The left and right main fuel tank filters were removed and disassembled. Both were absent of debris.

The flight controls were heavily fractured, but control continuity was established for the elevator and rudder to mid-fuselage. Both flight control wheels were broken off from impact; but the control column and linkages for the control yoke and rudder pedals were observed in the cockpit area. Both left and right seat rudder pedals, and the outboard rudder pedal for the right seat remained attached to their respective linkages. The right seat inboard rudder pedal had separated. Continuity to mid-cabin was established for the left- and right-wing flaps and ailerons. The left flap actuator appeared fully extended, and the right flap actuator was near the fully-retracted position.
The rudder trim was neutral, and the elevator trim was consistent with one-quarter nose-up trim. The landing gear selector handle in the cockpit was impact damaged but appeared to be in the retracted position. The left main gear remained attached to the left wing and the right main gear had separated. The nose wheel was under the fuselage and the tire had separated.

The cockpit area sustained extensive impact damage, with more of the damage occurring to the left (pilot) side area. The throttle levers were positioned between mid- and full power and bent to the left. Both propeller levels were full forward. Both mixture control handles were full forward and bent to the right. The flap selector handle was in the fully extended position.

The left engine remained attached to the airframe by the engine mount and sustained moderate impact damage. Visual examination of the engine revealed no obvious evidence of pre-impact mechanical malfunction or fire.

The propeller was removed to facilitate the examination. The top spark plugs and the vacuum pump were removed, and the crankshaft was rotated by hand via the vacuum pump drive spline. The crankshaft rotated freely, and compression and valve train continuity were established to each cylinder and to the accessory section. The combustion chamber of each cylinder was examined through the spark plug holes utilizing a lighted borescope; no anomalies were observed. The bottom spark plugs were removed and examined along with the top spark plugs. Each plug, except the No.2 top plug, which was oil-soaked, was gray in color consistent with normal wear as per the Champion Check-a-Plug chart.

The propeller governor was partially displaced from the mounting pad due to impact. The pitch control rod remained securely attached at the control arm and the drive rotated freely. The gasket screen was absent of contamination.

The left and right magnetos, along with their respective ignition harnesses (which were impact damaged), remained attached to the engine. The magneto-to-engine timing check found both magnetos beyond manufacturers limits; however, the magneto flanges (under each clamp) were displaced during impact. The magnetos and their damaged harnesses were removed and produced spark at each distributor tower when manually rotated.

All engine compartment fuel lines were found in place and secure at their respective fittings. Fuel was found during the removal of various fuel system components.

The fuel injection servo remained securely attached at the mounting pad of the plenum. The throttle/mixture controls were found securely attached at their respective control arm of the servo. The serrated engagement at each control arm was securely mated and secured by the locking nut. The plug on the side of the injector body was secure with the safety wire in place. The servo fuel inlet screen was free of contamination. The fuel injection servo and induction system were examined and observed to be free of obstruction.

The Shadin fuel flow transducer was examined. The transducer fuel lines remained attached at the inlet and outlet. The transducer was observed to flow when air was applied, and the vane could be heard spinning.

The mesh air filter within the airbox remained intact and free of visible contaminants. The automatic alternate air door remained intact and functioning.

The slope controller was functionally tested at Machen, Inc., under the supervision of the FAA. The controller functioned normally.

Each engine was equipped with a Hartzell three-bladed propeller. Both propellers remained attached to their engine crankshaft mounting flanges during the impact sequence. Both propeller spinner domes were crushed, torn and partially formed around the hub area. Both propeller assemblies displayed packed dirt in the spinner and around the hub components.

Examination of the left propeller revealed that the left hydraulic unit separated from the hub unit and was crushed but remained attached to the propeller assembly via the pitch change rod. The pitch change rod was cut by a hacksaw to remove the feathering spring danger and facilitate propeller removal from the engine. One of the counterweights was also removed to facilitate cutting the pitch change rod. The left and right propeller blades had similar damage; two blades were bent aft and twisted towards low pitch. The bending on the third blade was slightly forward and twisting was unremarkable. The propeller mounting flange and hardware appeared intact. The blades appeared to be at a low pitch angle.

There was distinguishable chordwise/rotational scoring on the cambered side of the blade near the leading edges. There was also leading-edge gouging with material deformation toward low pitch. All three pitch change knobs were fractured, and the associated preload plates had damage indicating forceful rotation towards low pitch.

Examination of the right propeller revealed two blades were bent aft and twisted towards low pitch. The bending and twisting on the third blade appeared unremarkable. The hydraulic unit separated from the hub unit threads and the cylinder was buckled/bent to one side. The R2 blade retention pocket was fractured in a helical path direction suggesting rotation. The propeller mounting flange and hardware appeared intact. The blades appeared to be at a low pitch angle.

There was distinguishable chordwise/rotational scoring on the cambered side of the blade near the leading edges. There was also leading-edge gouging with material deformation towards low pitch. Two of the three pitch change knobs were fractured, and the associated preload plates had damage indicating forceful rotation toward low pitch. The low pitch stops also displayed an impact mark indicating the pitch change mechanism was forced in the low pitch direction during impact.

All propeller components were accounted for at the point of impact with terrain. There were no discrepancies noted that would prevent or degrade normal propeller operation prior to impact. All damage was consistent with high impact forces.

The damage observed to both propellers indicated power symmetry at the time of impact. Chordwise/rotational scoring on the cambered side of the blade and leading-edge gouging were consistent with rotation at the time of impact and suggested a low/idle power condition. Internal impact marks indicated that the propeller blade angle was in the low range of normal operation during the impact sequence and was forcefully rotated towards low pitch.

No mechanical discrepancies were noted with either engine or their respective propeller system that would have precluded normal operation at the time of impact.

The airplane was equipped with a JPI EDM-760 engine data monitor and a Shadin Fuel Flow Indicator. The Shadin unit sustained extensive impact damage. The non-volatile memory device was removed and installed in a laboratory surrogate indicator. Upon applying power, only error messages were displayed.

The JPI EDM-760 sustained extensive impact damage but contained data from the accident flight. The duration of the recording was about 1 hour and 50 minutes. The unit recorded time with the first data sample based on the unit's internal clock, which was set and updated by the operator. The time on this unit appeared to be EDT and was about 12 minutes ahead from the actual time of the accident. The downloaded parameters included battery voltage, engine exhaust gas temperature (EGT), and cylinder head temperature (CHT) for both engines. There were no parameters for fuel pressure or fuel flow. A review of the recorded data revealed that, about 1030, there was a jump followed by a decrease in EGT and CHT temperatures for both engines. The temperatures decreased for about 9 minutes, during which time the right engine EGT data spiked twice. Both engine's EGT and CHT temperatures returned to normal, consistent with both engines producing power, for the remaining 5 minutes of flight before the data ended about 1044.

Medical And Pathological Information

An autopsy of the pilot was conducted by the Office of Chief Medical Examiner, Augusta, Maine, on July 31, 2018. The cause of death was determined to be "extensive blunt force trauma."


Toxicological testing performed by the FAA's Forensic Sciences Laboratory was negative for ethanol and drugs.

Accident Number: ERA18FA206
Date & Time: 07/30/2018, 1055 EDT
Registration: C-GRRS
Aircraft: Piper PA60
Injuries: 3 Fatal
Flight Conducted Under: Non-U.S., Non-Commercial 

On July 30, 2018, about 1055 eastern daylight time, a Canadian registered Piper PA-60-602P, C-GRRS, was destroyed when it impacted terrain while on approach to land at the Greenville Municipal Airport (3B1), Greenville, Maine. The private pilot and the two passengers were fatally injured. The airplane was registered to and operated by the pilot under Canadian Aviation Regulations as a recreational flight. An instrument flight rules flight plan was filed for the flight that departed the Pembroke Airport (CYTA), Pembroke, Ontario, Canada, about 0905, and was destined for the Charlottetown Airport (CYYG), Prince Edward Island, Canada. Visual meteorological conditions prevailed at the of the accident.

According to the Pembroke Airport manager, the pilot flew to Pembroke on July 27, 2018, and purchased 117 gallons of 100 low lead fuel. The airport manager, who personally fueled the airplane that day, said he topped-off both wing tanks and the center tank with fuel. He did not fuel the auxiliary fuel tank. The airplane was then placed in a hangar until the morning of July 30, 2018, when the pilot departed for CYYG.

A preliminary review of air traffic control (ATC) communications revealed that after the pilot departed, he climbed and leveled the airplane at 23,000 ft mean sea level (msl). About 90 minutes into the flight, the airplane began to descend, and the pilot reported a loss of power to ATC. The pilot was vectored to 3B1. He told ATC he had the airport in sight and intended to make a left downwind entry for runway 14.

A witness was standing on the airport's apron near the terminal building between runway 21 and 14 when he first observed the airplane approaching the airport from the south. The airplane was flying directly toward where he was standing. The witness said the airplane was "low" and about 400 ft above the ground. It flew over the center of the airport and made what appeared to be a left downwind entry for runway 21. There was no smoke trailing the airplane and the landing gear was retracted. The witness said both propellers were turning, but he could not tell how fast they were turning or if one was turning faster than the other. He was standing next to active construction equipment which prevented him from fully hearing the engines. When the airplane reached the approach end of runway 21, it began a "shallow" left turn. The nose of the airplane was "high" and the airplane was "going so slow." He said, "It was like it almost stopped in the air" right before the left wing suddenly dropped and the nose of the airplane dove toward the ground and disappeared behind an embankment. The witness saw a debris cloud and knew the airplane crashed.

A second witness, who was a pilot, was standing in front of a hangar on the southeast side runway 3/21 when he first observed the airplane approaching the airport from the west. It was "low" and about 500-600 ft above the ground. Instead of landing, the airplane continued to fly over the center of the airport. The witness said the airplane flew directly over him as it made a left turn and flew parallel of runway 3/21. He said both propellers were turning, and the engines were producing power; however, he could not estimate an engine speed. The witness could not recall if the gear or flaps were extended, but recalled the belly of the airplane was painted black. When the airplane flew past the approach end of runway 21, it began a "shallow" left turn and was flying "really slow." The bank angle continued to increase to a point where he could see the entire top of the airplane. The airplane then pitched up and it appeared to momentarily "stop" right before the left wing "stalled" and the nose pitched down toward the ground. The witness did not hear any increase in engine rpm prior to impact. He also said that he did not believe the pilot was trying to land on runway 21 because he was positioned too close to the runway.

The airplane came to rest in a field about 300 ft from the approach end of runway 21 on a magnetic heading of 220°. All major components of the airframe were accounted for at the site and there was no postimpact fire. The wreckage was contained to where it impacted the ground. The nose and forward fuselage area were compressed inward from impact; both engines were partially buried in the ground (neither propeller was feathered), and the empennage was compressed and twisted to the left. The tail section appeared undamaged and was twisted to the left. Both wings remained attached to the airframe at the wing root and sustained impact damage. The wing fuel tanks were breached. The center fuel tank (bladder-type) was breached, and the auxiliary fuel tank remained in the airplane but was breached. According to first responders, about 20 gallons of fuel was cleaned up at the site. The green vegetation forward of where the wreckage came to rest was discolored brown.

The airplane wreckage was retained for further examination.

The pilot, age 58, held a Canadian private pilot certificate for single and multi-engine land airplane, and instrument airplane. A review of the pilot's logbook revealed that as of July 27, 2018, he had a total of 590.3 flight hours, of which, 155.2 hours were in multi-engine airplanes. The pilot logged about 136 hours total in the accident airplane and about 82.6 of those hours were as pilot-in-command.

At 1056, weather at the Greenville Municipal Airport was reported as wind from 310° at 8 knots, variable between 260° and 360°, sky clear, temperature 23° C, dew point 14°, and an altimeter setting of 30.09 inches of mercury.

A plane made an emergency landing at Danbury Airport Sunday.

Police say a four-seat Piper Warrior plane had a problem with its landing gear while in the air. Two people were on board.

The aircraft made several flybys to allow the tower to check for damage and for emergency crews to prepare on the ground.

No one was injured during the landing.

The plane was towed from the runway.

DANBURY — A plane touched down safely at Danbury Airport on Sunday, despite a problem with its landing gear.

James Gagliardo, spokesman for the fire department, said the issue with aircraft’s left-side landing gear was discovered as the pilot was practicing landing on the runway.

Danbury firefighters and Emergency Medical Services were called to the airport around 11:30 a.m. and stood by as the four-seat Piper Warrior tried to land.

The pilot then successfully touched down gently and came to a full stop on the runway, according to a release from the fire department. Neither the pilot or passenger were injured, while the plane suffered little damage.

“Between the airport air traffic controller, the skilled pilot, and the joint response of the Danbury Fire, Police, EMS and Airport Administrators this couldn't have turned out any better,” Mike Safranek, airport assistant administrator, said in the release.

Fire units helped jack the aircraft and replace the gear, so the plane could be towed from the runway.

The helicopter pilot reported that while climbing out of a canyon at 30 knots indicated airspeed, about 50 ft above the ground, he felt a "hard vibration" in the cyclic and collective controls. He then saw that the airspeed gauge was reading zero knots and he felt the helicopter was being pushed down. The torque indicator rose to 120% without any cyclic and collective control input. He applied right cyclic, lowered the collective, applied right pedal to counter the torque, and turned the helicopter downslope and into the wind. He applied forward cyclic to better match the downslope of the terrain and raised collective, but the helicopter impacted terrain. The skids impacted the ground first followed by the main rotor blades. The helicopter rotated 180º to the right before coming to rest downhill, on its right side. Shortly after, a post impact fire ensued.

The helicopter was destroyed during the postimpact fire.

The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.

The pilot reported that the winds were gusting up to 30 knots in the canyon, "changing direction every minute or so."

Three incidents took place in Lander County on Saturday, Aug. 18: A helicopter crash involving employees with the Nevada Department of Wildlife (NDOW), the Sheep Creek Fire, and a burn-over of two firefighters responding to the fire.

The helicopter crash took place around 2 p.m. on Saturday afternoon, Aug. 18. It was a contract helicopter carrying a pilot and two NDOW biologists on a wildlife survey flight.

The pilot and one of the biologists had minor injuries, and the other biologist had injuries to their neck and back. All three are in good condition and the crash is being investigated by the Federal Aviation Administration (FAA) and National Transportation Safety Board (NTSB).

“We cannot stress enough the importance of safety with our employees and the public, and we are grateful everyone on the flight is safe,” said NDOW Director Tony Wasley.

Shortly after the crash, the Sheep Creek Fire was reported approximately 15 miles north of Battle Mountain. Crews from the Battle Mountain Volunteer Fire Department and the Bureau of Land Management (BLM) responded to the fire.

During the response, an engine from the Battle Mountain VFD was burned over injuring two firefighters. The firefighters were taken to a burn center and information on their status will be provided when it becomes available.

“Our thoughts and prayers are with the firefighters, their families and the entire community," said Lander County Manager Keith Westengard. "Lander County is a tight knit community and many are affected by this tragedy."

The Sheep Creek fire is currently at 7,000 acres and approximately five percent containment, and the cause remains under investigation. More information about the fire can be found in Inciweb at https://inciweb.nwcg.gov/incident/6157/.

“This situation highlights the dangers faced by all partners and agencies who assist with battling wildfires,” said acting BLM Nevada State Director Mike Courtney. “Our thoughts and prayers are with the firefighters and their families as they deal with the injuries and recovery.”

“The Nevada Department of Wildlife will also continue to keep the injured firefighters and their families in our thoughts and prayers,” added Wasley.
