Accident Sequence
During an approach to Lukla, the flight crew encountered poor weather conditions. Unable to locate the runway, they decided to divert to Simara Airport. However, visibility at Simara was insufficient, and the crew eventually elected to return to Kathmandu. While descending to runway 02, a generator failed. The crew did not declare an emergency; instead, they contacted their maintenance base and were unable to switch to the backup generator. Shortly after attempting to reset the battery system, the aircraft entered an uncontrolled descent and crashed in a rice paddy field. The aircraft disintegrated on impact. The wreckage was found approximately 30 km southeast of Tribhuvan Airport.

Investigation and Probable Cause
The official investigation determined the probable cause to be a loss of control on approach following the failure of a generator for undetermined reasons. No additional causal factors were identified in the source.
