Introduction
An aircraft arriving from Kathmandu experienced a runway excursion during landing at Meghauli Airfield. The flight was uneventful until the descent phase.
Sequence of Events
The crew initiated the descent to Meghauli Airfield. On final approach, the aircraft was too high and touched down approximately 1,148 feet beyond the runway threshold. The runway at Meghauli is 3,500 feet long. Due to the excessive touchdown point, the remaining landing distance was insufficient. The aircraft was unable to stop on the wet grassy runway, overran the end, and came to rest in a ravine. All 31 occupants exited the aircraft without injury. The aircraft sustained damage beyond economical repair.
Probable Cause
The official investigation determined the probable cause to be a wrong approach configuration by the crew, who landed the aircraft too far down the runway, reducing the available landing distance. Additionally, poor braking action was reported as the grassy runway was wet.
