The crash was attributed to the pilot's non-adherence to the written procedure for an approach to Imphal. The crew decided to violate the approach procedure by taking a short cut and eventually slammed the aircraft into the hilly terrain. During the approach, the crew did not adequately monitor their instruments, despite the deteriorating weather condition at the time. Their actions were influenced by the pilot's decision to solely rely on his extreme familiarity with the terrain.[1]
