During the takeoff roll on runway 20, the aircraft started to skid. Halfway down, the crew decided to abandon the takeoff procedure but the aircraft was unable to stop within the remaining distance. It overran and came to rest in a ravine. Both pilots escaped uninjured and the aircraft was damaged beyond repair. Weather conditions were good at the time of the accident with an OAT of 18° C. and light wind. The Surkhet Airport runway 20/02 is grass and is 3,400 feet long. It was reported that at the time of the accident, the turf was quit high and wet due to the morning dew which was considered as a contributing factor.

Circumstances:

The aircraft departed Kathmandu-Tribhuvan Airport on a cargo flight to Sharjah with an intermediate stop in New Delhi, carrying five crew members and a load of 21 tons of woolen carpets. After takeoff from runway 20, the crew continued to climb but failed to realize his altitude was insufficient. The aircraft struck the slope of Mt Champadevi located 11 km southwest of the airport and disintegrated on impact. All five crew members were killed.

Probable cause:

The accident occurred as the crew after take off did not adhere to the published Standard Instrument Departure (SID) procedure for runway 20 at Kathmandu, Nepal.
The following contributory factors were identified:
- Incomplete departure briefing given by P1 while other cockpit activities were in progress,
- The unexpected airspeed decay to V 2 -3 during initial right climbing turn South of the VOR which occurred while P2 was busy with ATC,
- The improper power and climb profile used by P1 after rolling the aircraft out on a southwest heading following the initial airspeed loss,
- The inadequate intra cockpit crew coordination and communication as the aircraft proceeded to and across the KTM VOR 4 DME arc before recommencing a shallow right turn, and
- The incorrect and slow response to the initial and subsequent GPWS activation prior to the collision with the terrain.

The following findings were identified:
- The crew failed to follow the pre-takeoff checklist,
- The takeoff procedure was initiated with the flaps retracted in the full up position,
- The pilot-in-command started the rotation at an insufficient speed,
- The aircraft stalled during initial climb and the distance between the aircraft and the ground was insufficient to expect recovery,
- Winds from 25-35 knots were gusting at the time of the accident.

Circumstances:

The pilot, sole on board, departed Kathmandu-Tribhuvan Airport on a positioning flight to Namche Bazar to pick up passengers. During the pre-flight briefing, he was informed about the good weather conditions along the route and at destination. But en route, these conditions deteriorated and upon arrival, clouds were present up to 3,600 metres. He made several circuits expecting weather improvement. Few minutes later, he saw a hole in the clouds and initiated a descent when the aircraft struck the slope of Mt Kongri Himal located 3 km north of the airfield. The aircraft was destroyed and the pilot was killed.

Probable cause:

Controlled flight into terrain.

Circumstances:

Following an uneventful flight from Kathmandu, the crew started the descent to Meghauli Airfield. On final, the aircraft was too high and landed too far down the runway, about 1,148 feet past the runway threshold (Meghauli Airstrip is 3,500 feet). Unable to stop on a wet grassy runway, the aircraft overran and came to rest in a ravine. All 31 occupants escaped uninjured while the aircraft was damaged beyond repair.

Probable cause:

Wrong approach configuration on part of the crew who landed the aircraft too far down the runway, reducing the landing distance available. Also, it was reported that the braking action was poor as the grassy runway was wet.
