Circumstances:
Following an uneventful and short flight from Pokhara, crew was authorized to land on runway 24 with a wind component between 8 and 12 knots. For unknown reasons, captain preferred to land on runway 06 with a tailwind component which exceeded the company’s standard operating procedure. Flare was long and aircraft landed 776 feet past the runway 06 threshold (runway 06 is 2,424 long). 194 feet after touch down, aircraft left runway to the right, went through a grassy area and rolled for 705 feet before coming again onto runway. Captain decided to perform a go around and increased the engine power but aircraft did not lift off due to insufficient speed. It overrun, went down an embankment and eventually came to rest, broken in two, in the bank of the Kaligandaki River. All occupants were injured, six of them seriously.
Probable cause:
The Accident Investigation Commission has determined the most probable cause of the accident was the inappropriate conduct of STOL procedure and landing technique carried out by the PIC, during landing phase and an endeavor to carry out take off again with no sufficient airspeed, no required lifting force and non availability of required runway length to roll. Contributory factors to the occurrence is the absence of proper CRM in terms of communication, coordination and briefing in between crew members on intention and action being taken by PIC, during pre and post landing phase.
