The airline has successfully secured two ATR 72 planes from Novoair Airlines, with one anticipated to arrive in Nepal either on Friday.
It is likely that the Pilot Monitoring (PM) had misidentified and moved both condition levers to FEATHER when the Pilot Flying (PF) called for flaps 30.
As per the preliminary report, the Yeti Airlines flight experienced a loss of thrust and descended when the propellers of an engine entered a feathered position.
