Pilatus PC-6 (Porter & Turbo Porter)

The single engine aircraft was completing a local training flight at Iquitos-Moronacocha Airport, carrying five pilots. On short final, the single engine airplane lost height, struck the ground and crashed near the runway threshold. All five occupants were injured and the aircraft was damaged beyond repair.

The aircraft ran off runway 30 at the Casas de los Pinos aerodrome while landing. The aircraft, used for parachuting operations, was making a reconnaissance flight before the parachuting flights, which were scheduled for later. According to the pilot's statement, during the flare, and before touching down, a gust of wind lifted the left wing. The pilot used left rudder and tilt to try to level the aircraft, but could not keep it from exiting the runway. As stated by the pilot, the approach was performed without flaps, at a speed of 70 knots and with the aft gear locked. The aircraft ended up 25 metres from the edge of the runway on a heading of 190°, resting on its lower fuselage, which was damaged along its underside, as were the left aileron and the horizontal stabilizer. The right main landing gear was bent outward, the left gear had detached and was 30 metres away from the aircraft, and the propeller had detached at the reduction gearbox and was next to the aft landing gear to the left of the aircraft. Both occupants were able to exit the aircraft under their own power. The pilot received a slight injury to his chin and the passenger was unhurt.

The aircraft departed Chanthaburi Airport for a cloud-seeding mission with four passengers and a pilot on board. Shortly after takeoff, while climbing, the engine failed. The aircraft stalled and crashed, bursting into flames. A passenger was seriously injured while four other occupants were killed.

The airline transport certificated pilot with 10 skydiving passengers began a takeoff in a tailwheel-equipped and turboprop powered airplane on a CFR Part 91 skydiving flight. As the airplane started its climb, the pitch angle of the nose of the airplane increased until the airplane appeared to stall about 50 to 100 feet agl. It descended and impacted the runway in a left wing, nose low attitude. Several FAA inspectors responded to the accident site and documented the accident scene and the airplane systems. The inspectors reported that flight control continuity was established, and they noted that the stabilizer appeared to be in a nose up trim position. Measurement of the stabilizer trim position equated to a 56.5 percent nose up trim condition. The airplane's horizontal stabilizer trim system is electrical. An electric trim indicator, and a trim warning light were installed in the upper left portion of the instrument panel. The light will illuminate if "full-up" trim is set, and the engine is producing over 80 percent power. A placard stating, "Set Correct Trim for Takeoff," was installed on the lower instrument panel in front of the pilot position. The airplane's flight manual contains a "Before Takeoff" warning, which states, in part: "Warning - An extreme out-of-trim stabilizer can, in combination with loading, flaps position and power influence, result in an uncontrollable aircraft after the aircraft leaves the ground." In addition, a caution states, in part: "Caution - Failure to set correct trim settings will result in large control forces and/or unrequested pitching/yawing." Pilot actions listed in the "Before Takeoff" checklist include stabilizer trim settings. The airplane contained seat belts for all passengers, but the pilot's shoulder harness was not used, as it was folded and tie-wrapped near its upper attach point.

Crashed in unknown circumstances in the sea off Prachuap Khiri Khan while completing a local training flight. The pilot, sole on board, was killed.
