Positioning

As the aircraft was taxiing for takeoff, witnesses noted the left rear baggage door was unlocked and hanging down. A warning was relayed to the pilot via the tower, but by then the aircraft was airborne and the pilot had reported a control problem. During lift-off, the aircraft pitched up sharply and entered an immediate right bank of about 45°. As the gear retracted, the bank angle decreased to about 20°. The aircraft was reported to yaw slightly from side to side and circle to the right while climbing to about 1,000 feet. A witness (in radio contact) asked the pilot about the problem; the pilot replied the controls (ctls) were locked to one side. On advice of others, the pilot tried to control the aircraft with engine power adjustments, but the aircraft lost altitude to about 200 feet agl. Subsequently, while maneuvering, it struck a tree, then hit a utility pole and crashed. During impact the lower fuselage, which housed the flight control linkages, was badly damaged. No preimpact mechanical problem was verified concerning the flight controls, autopilot or trim. A pilot, who had previously flown the aircraft with the baggage door open, said he experienced no adverse control problems. The pilot, sole on board, was killed.

Witnesses reported a normal takeoff. Radar indicated the aircraft turned right as cleared and began cruise at 1900 feet, heading northwest at 235 knots. 65 seconds after calling clear of the control zone the aircraft's radar track ended. The aircraft was fragmented by the impact with all flight control surfaces and aircraft extremities found at the impact site. Pitch trim was found in the normal cruise setting with gear, flaps, and spoilers in the retracted position. Examination of the engines indicated operation at impact. Aircraft struck the terrain in approx 80° nose down, wings level attitude and heading opposite to the previous direction of flight. In flight simulator tests, with the aircraft initially in level flight at 1,900 feet and then rolled inverted and the pitch control moved aft, the aircraft attitude was similar to the attitude at impact. There were two unauthorized passengers on board, one was the copilot's wife. The impact point was in a very small region of uncontrolled airspace very near the copilot's and relative's homes. The copilot was new to jet operations. The aircraft departed with several discrepancies uncleared. All four occupants were killed.

The pilot was repositioning the airplane from an on-demand air taxi freight flight. He was en route from Rochester, NY to Huntsville, AL with a planned refuel stop at Louisville, KY. Near Falmouth, KY he changed his destination to Lexington 'due to a developing engine problem'. He saw the airport at Cynthiana and elected to land there. While on downwind, he noted the left engine cowling turning black and on base noted flames from the left engine. He reptd shutting the engine down and feathering the propeller but did not activate the fire extinguisher. During the landing roll, the airplane departed the runway to the right, and collided with the airport wind 't', a pole and a 't' hangar. Post accident investigation revealed that the left prop was not feathered and the fuel was not shut off. The left brake was ineffective due to fire damage. The evidence indicated that the fire began in the vicinity of the left engine accessory section. The specific fuel source of the fire was not identified.

The copilot was flying the aircraft as it was being ferried after minor maintenance. As they were in a descent and were approaching the destination airport, the captain noted a left engine torque fluctuation of 20% to 30% and elected to secure the engine, although no yawing was noticed. During shutdown, the left propeller did not feather and drag increased until the aircraft would not sustain level flight. An attempted restart of the left engine was unsuccessful, so the captain tried to feather it again. However, the left propeller still did not feather. Subsequently, the pilots were forced to land in an open field on uneven terrain and the aircraft was damaged. An extensive investigation was made, but no cause could be found for the torque fluctuation, nor could the condition be duplicated, however, the investigation did note that the air and ground procedures for engine shutdown were similar. A variation in the ground shutdown procedures allowed for engagement of the start latches.

The crew started the descent to Ercan Airport in limited visibility due to marginal weather conditions. After being cleared for a VOR approach, the captain cancelled the IFR flight plan and descended prematurely at an altitude of 2,000 feet. He elected to make a turn to avoid the mountain when the aircraft struck the slope of a mountain (954 meters high) located about 16 km north of Ercan Airport. The aircraft disintegrated on impact and all 15 occupants were killed. The flight was completed on behalf of JAT Yugoslav Airlines. On board were six Turkish citizen (crew), seven Yugoslav citizens and two British.

During the takeoff roll on runway 21, just before reaching V1 (112 knots), the captain thought that the right engine lost power. He decided to abandon the takeoff maneuver and initiated an emergency braking procedure. Unable to stop within the remaining distance, the aircraft overran at a speed of about 60-70 knots, rolled in a snow covered field and eventually collided with an embankment, coming to rest, broken in two. Both pilots were injured.

On final approach, the pilot encountered strong crosswinds when he lost control of the airplane that crashed on rocks located near a beach. The aircraft was destroyed and the pilot, sole on board, was killed.

The crew was completing a positioning flight from Lyon-Satolas Airport to Le Puy-Loudes Airport, Haute-Loire. On final approach by night, at an altitude of 500 feet, the crew positioned both propellers to fine pitch when both engines failed simultaneously. The airplane stalled and crash landed in an open field located few hundred meters short of runway threshold. Both pilots escaped with minor injuries while the aircraft was damaged beyond repair.

While enroute to home base after delivery of revenue cargo, the pilot experienced a total loss of engine power in both engines due to fuel exhaustion. The pilot performed emergency procedures and set the aircraft up for a forced landing in a grassy field on the edge of a lake. The aircraft initially impacted a tree and the rocky berm of the shoreline. The contact with the berm caused the landing gear to break off, the aircraft swerved around and skidded backwards before coming to a rest about 150 feet from the lakeshore. Post accident investigation revealed less than 2 gallons of fuel in each wing tank.

The pilot, sole on board, was completing a positioning flight from Teesside to Leeds where passengers should embark for Alicante, Spain. On approach, the visibility was poor due to low clouds. After being cleared to descend to 3,000 feet then to land on runway 14, the aircraft descended too low and crashed on the top of a hill located 3,4 km short of runway threshold. The pilot was killed.
