On 15 January 2023, an ATR 72-500 positioning visually for an approach to Pokhara 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.
