On 15 January 2023, an ATR 72-500 positioning visually for an approach to Pokhara, Nepal, suddenly departed controlled flight and impacted terrain. The aircraft was destroyed by the impact and all 71 occupants were killed. A type-experienced training captain was overseeing new airport familiarisation for a line captain acting as pilot flying. The training captain unintentionally feathered both propellers in response to a call for flaps 30 but did not recognise their error or respond to calls that no power was coming from the engines. The airline’s operational safety-related processes and regulatory oversight of them were both assessed as comprehensively inadequate.
Description
On 15 January 2023, an ATR 72-500 (9N-ANC) operated by Yeti Airlines on a scheduled domestic passenger flight from Kathmandu to the recently-opened Pokhara International airport as NYT691. It was being used for a line captain’s familiarisation with the new airport under supervision of a type-experienced training captain. The aircraft was about to turn onto a visual final approach for runway 12 at destination in day visual meteorological conditions (VMC) when it suddenly departed controlled flight and began a rapid descent before impacting uninhabited terrain. The impact and post-crash fire destroyed the aircraft and all 68 passengers and the four crew members on board were killed. There were no injuries to people on the ground or damage to ground structures.
