Accident: Lukla, Nepal 25-May-2004. The aircraft, on a cargo flight from Kathmandu, crashed into the Lamjura hill while on approach to Lukla. At the time of the crash there was heavy cloud buildup over the 3,600 m Lamjura Pass which planes have to cross to get into Lukla. The Nepalses accident investigation committee concluded that the captain provided false information to the Area Control Centre by declaring that he was proceeding south of the track while proceeding along the direct track all the time. The only occupants, three crew, were killed. It was concluded that the hazardous behaviour and attitudes of the captain like over-confidence, being carefree, casual non-compliance of SOPS and violation of regulations had caused the accident. The committee also raised questions on Yeti Airlines’ policy for flying in adverse weather, diverting philosophy, communications procedures, monitoring of flight crew, and the company’s inability to initiate in-house investigations and execute corrective actions when required.
