Piper PA-31-310 Navajo

The airplane departed from a maintenance facility, after installation of the right engine, with an unknown quantity of fuel. Shortly after takeoff, the pilot reported that he had "lost" an engine. He requested vectors for the departure airport, then amended his request to an alternate destination. From the original distress call to the last recorded radar target, approximately 2 ½ minutes, the airplane descended from 2,500 feet to 700 feet and slowed from 190 knots to about 87 knots. Several witnesses described the engine sound as "rough", and "cutting in and out" before the airplane descended out of view and sounds of impact were heard. The left wing was consumed by post-crash fire. Forty gallons of fuel were drained from the right inboard and nacelle tanks. Only trace amounts of fuel were visible in the right outboard tank. Both fuel selectors were found in the outboard tank position. Examination of flight times and ground-maintenance run times revealed that the engines were run for approximately 3 hours with the outboard tanks selected. The outboard tanks each held 40 gallons, for a total of 80 gallons. According to the pilot's operating manual, the fuel consumption rate at the maximum endurance power setting was 28 gallons per hour.

The twin engine aircraft departed Biscarosse Airport, Landes, at 1629LT, on a private flight to Alicante, carrying five passengers and one pilot. At 1840LT, while descending to Alicante, the pilot contacted ATC and reported a low fuel situation. After being vectored to Albacete-Los Llanos AFB, he modified his route and started the descent for an approach to runway 09. Four minutes later, at an altitude of 3,000 feet and a distance of 8 NM, he declared an emergency following an engine failure. Two minutes later, the aircraft crashed near Chinchilla, about 10 km southeast of the airport. All six occupants were rescued and the aircraft was damaged beyond repair.

The airplane collided with terrain 200 yards short of the runway during an emergency landing following a loss of engine power. The pilot was on an intermediate leg of a ferry trip. Approximately 300 miles from land, the fuel flow and boost pump lights illuminated. Then, the right engine failed. The pilot flew back to the nearest airport; however, approximately 200 yards from the runway, the airplane stalled and the right wing dropped and collided with the ground. The fuel system had been modified a few months prior to the accident to allow for a ferry fuel tank installation. Post accident examination of the airplane could not find a reason for the power loss.

The PA-31-310, registration C-FARL, serial number 31306, operated by Les Ailes de Gaspé Inc., with one pilot and two passengers on board, was on a visual flight rules flight from Îles-de-la-Madeleine, Quebec to Gaspé, Quebec. While en route to Gaspé, the pilot was informed about weather conditions at his destination, which were a ceiling at 500 feet and visibility of ¾ mile in fog. The pilot requested clearance for an instrument approach, which he received at approximately 1857 eastern daylight time. A few seconds later the pilot switched on the aerodrome lights with his microphone button. That was the last radio transmission received from the aircraft. When the aircraft did not arrive at its destination, emergency procedures were initiated to find it. The wreckage was found the next day at 1028 eastern daylight time on a hilltop 1.2 nautical miles (nm) north-east of the airport. The aircraft was destroyed, but did not catch fire. The three occupants were fatally injured.

While cruising under VFR mode by night and marginal weather conditions, the twin engine struck the slope of a mountain located near Urabá. The aircraft left the airport of Medellín-Enrique Olaya Herrera at 1700LT with a Mexican pilot and a Colombian passenger on board bound for Panama City. The aircraft was destroyed and both occupants were killed.

The airplane experienced an in-flight loss of control and crashed into a residential area. The flight departed VFR and when near the destination airport flew between areas with VIP Level 5 reflectivity. There was no record of a preflight weather briefing. The flight continued towards the destination airport and encountered lesser intensity reflectivity. An individual at the destination airport reported hearing an occupant of the airplane ask, "...for an advisory for the field", and "...what the weather was like." The individual at the airport advised that the winds appeared to be in favor for runway 16, which was left hand traffic, the runway was wet, and the rain seemed to be letting up. There were no further communications from the accident aircraft. A pilot-rated witness located north of the destination airport, and nearly due west of the accident site reported seeing the airplane on what he thought was final approach to runway 16, but the airplane was "very low." The witness reported the airplane made a, "sudden, sharp turn to the left [flying eastbound]." He then lost sight of the airplane and proceeded to the accident site. Another pilot-rated witness who was located in a vehicle approximately 1/4 mile west-northwest of the accident site reported observing an airplane flying from the northwest. The airplane banked to the left flying eastbound at a, "...very slow airspeed and banking and yawing left and right." While flying eastbound it appeared to him that whomever was flying the airplane was executing a go-around as evidenced by the landing gear retracting, followed by the flaps. The airplane then appeared to climb which appeared very unstable, again yawing left and right. The airplane then banked to the right, stalled, and entered a spin impacting the ground. Still another witness who was located approximately 1/10th of a nautical mile east-southeast from the accident site reported he came out of his house after the rain ended and was facing west. He saw the accident airplane from the northwest and thought it had descended lower than normal. The airplane was flying above the tops of nearby trees and while flying in a southeasterly direction, pitched up, "darn near got 90 degrees", rolled to the left, and descended straight down. He reported that he did not hear the engines, and thought he should have been able to hear them if the pilot had "revved them up." He estimated his view of the flight lasted approximately 10-15 seconds, and couldn't tell if the landing gear was extended. He did not see any smoke trailing the airplane, and after the impact he ran into his house, called 911, got into his car, and drove to the scene. He heard an explosion, and saw flames. He got to the airplane and helped rescue a passenger who was beating on the aircraft's door. The airplane descended nearly vertical in a residential area and damaged trees approximately 30 feet above ground level. A post crash fire consumed the cockpit, cabin, portions of both wings, and portions of both engines. Examination of the flight controls, both engines, propellers, and propeller governors revealed no evidence of preimpact mechanical failure or malfunction. Accessories of both engines including the magnetos were destroyed by the post crash fire. Additionally, both servo fuel injectors were heat damaged which precluded bench testing. During disassembly of the right servo fuel injector, the hub stud was found separated from the hub at the fuel diaphragm. No determination was made whether this occurred during disassembly or occurred preimpact. No determination could be made as to who was operating the controls at the time of the accident.

The pilot stated that he and his wife were en route to a medical conference which was to be held aboard a cruise ship that was departing from Fort Lauderdale, Florida, at 1700. He stated that both tanks were full of fuel when he departed the Canton Regional Airport, Canton, Ohio, en route to Fort Lauderdale Executive Airport. According to the pilot, the inboard tanks had been selected for the first hour and a half and the outboard tanks for the following two hours. He said the flight was vectored around thunderstorms, and during the descent, when about 12 miles to the north of Palm Beach International Airport, Palm Beach, Florida, the left engine ceased operating. He said that at this time he noticed that both inboard fuel indicators showed the tanks to be empty, and he switched to the outboard tanks, both of which were shown to be a quarter full. The pilot stated that two minutes later both engines began to surge, and after making an emergency radio communications call, he was advised by the FAA Air Traffic Controller that Tailwinds Airport was located 4 miles to the west. Unable to reach the runway at Tailwinds Airport, the pilot said he made a forced landing in an orange grove. the pilot also said that prior to the accident, there had not been any mechanical failure or malfunctions to the airplane or any of its systems. Examination of the accident site revealed that the airplane had incurred substantial damage, and there was little or no fuel present at the scene. Follow-on examination of the airplane, its fuel system and both engines revealed no anomalies.

A witness at the airport stated the airplane appeared to use half of the 8,000-foot runway on takeoff roll, and the climb out appeared "very flat." During climbout, the pilot reported to the tower controller the airplane "lost an engine," and he announced intentions to return to the runway. The controller stated he noticed the airplane continued straight out and appeared to be losing altitude. Witnesses north of the airport observed the airplane flying low and described its engine noises as "erratic," "skipping," "sputtering," and "some sort of backfire." One witness stated the airplane was moving slowly to the north with a high nose-up angle, and the airplane "appeared to stall" then dove vertically into the trees. Examination of the accident site revealed wreckage debris and broken trees were scattered approximately 120 feet. The airframe, engines, and the right propeller sustained fire damage. The left propeller, top forward portion of the left engine case, and the left propeller gear shaft and bearings were not located. Examination of recovered components revealed no evidence of mechanical malfunction could be determined. According to the Pilot's Operating Handbook for the Piper PA-31P, the stall speed for the airplane with the gear and flaps up is: "(7800 lbs) 80 KCAS, 81 KIAS."

The twin-engine airplane was destroyed when it impacted trees and terrain shortly after takeoff. The airplane was consumed in a post-impact fire. Witnesses reported seeing the airplane climbing at a lower than normal rate just after takeoff. One witness did not hear the airplane. Another witness reported that the airplane sounded labored and this is what drew his attention to the airplane. The airplane came to rest in a wooded area about 3,500 feet from the departure end of the runway, and 700 feet left of the extended runway centerline. The wreckage path through the trees was about 65 degrees left of the runway heading. The first piece of wreckage along the wreckage trail was the left wingtip. Examination of the right propeller revealed chordwise scratching, leading edge damage, and bending and twisting opposite to the direction of rotation. In addition, several tree cuts were observed that were predominately on the right side of the wreckage path. No evidence of rotation was noted with respect to the left propeller, propeller blades, or propeller spinner. On-scene examination revealed no pre-impact anomalies with respect to the airframe, right engine, or right propeller. Follow-on examination of the left engine and propeller revealed no pre-impact anomalies. Calculations based on the power setting table, airspeed chart and en-route distance showed that the airplane would have burned a total of 56 to 71 gallons (28 to 35.5 gallons per side) of fuel for the previous leg of the round-trip flight. The main fuel tanks held a total of 112 gallons of fuel (56 gallons per side). Based on the fuel burn calculations, this quantity of fuel would not have been sufficient to complete the round-trip flight on the main fuel tanks alone. The outboard auxiliary fuel tanks held 40 gallons per side. The left fuel selector was found positioned to the inboard main fuel tank and the right fuel selector was found positioned to the outboard auxiliary fuel tank. The airplane flight manual for the airplane stipulates that only the main fuel tanks be used for takeoff and landing. No fuel was obtained for the return flight.
