Aircraft flight cycles:

Circumstances:

Less than two minutes after takeoff from Værøy Airport runway 25, while climbing in marginal weather conditions, the aircraft banked left then entered an uncontrolled descent and crashed in the sea in a near vertical attitude about 1,8 km from the airport. The aircraft was destroyed and all five occupants were killed. When the crew started to roll at the airport, the wind was gusting to 57 knots which was 7 knots above the maximum allowable limit for ground operations. After takeoff, the aircraft encountered wind gusting to 34 knots which was 14 knots above the maximum allowable limit for flight operations. Excessive wind component caused the stabilizers/elevator to fail, causing the aircraft to enter an uncontrolled descent and to crash in the sea.

Probable cause:

The cause of the accident was that the plane during departure came into the wind that exceeded the aircraft's design criteria. Thus there was a break in the horizontal stabilizer / elevator which meant that the plane could no longer be controlled.

Circumstances:

During the takeoff roll on runway 19L, at a speed of about 100 knots, the aircraft deviated from the centerline to the right. The pilot-in-command corrected with rudder but finally, the aircraft struck the right shoulder of the runway then veered off runway. It rolled in a grassy area and came to rest few dozen meters further. All 52 occupants evacuated safely while the aircraft was damaged beyond repair due to structural damages to the fuselage.

Probable cause:

It was determined that the right engine was not running properly during the takeoff roll, creating an asymmetric thrust and the aircraft to deviate from the centerline to the right. Investigations reported that the aircraft was subject to maintenance the days prior to the accident and modification were made to the fuel pump but nothing was entered in the airplane logbook. It was determined that the fuel pump overspeed governor had been set too low and a low power output at high TGT.

Following a wrong approach configuration at Guilin Airport, the three engine aircraft landed too far down the runway. Unable to stop within the remaining distance, the aircraft overran, lost its right main gear and came to rest in a grassy area. All 107 occupants evacuated safely while the aircraft was damaged beyond repair. Weather conditions were poor at the time of the accident with rain showers and limited visibility. Thus, the runway surface was wet and the braking action was limited.
