Descripción:
Flight 257 departed Calcutta at 11:45 for a flight to Imphal. While positioning for a runway 04 ILS approach, the aircraft crashed into a hill.

PROBABLE CAUSE: "The accident occurred by reason of a grave error on the part of the Pilot-in-Command in not adhering to the operational flight plan and ILS let down chart and not realizing that his early descent to 10,000 feet and turning right for outbound leg without reporting overhead VOR would result in loss of time
reference and as such misplace him in the hilly terrain. The Pilot-in-Command's action may have been influenced by his extreme familiarity with the terrain".
