Misidentification and Erroneous Selection of Propeller Feathering Controls in Flight
EASA Safety Information Bulletin 2024-08 is issued to raise awareness about the risk of misidentification and erroneous selection of propeller feathering controls in flight on large CS-25 turboprop aeroplanes. The bulletin references an accident involving an ATR72/212A version 500 near Pokhara International Airport, where inadvertent feathering of both propellers led to total thrust loss and a fatal crash. It highlights the importance of flight crew alerts and cockpit indications in detecting such errors promptly to prevent loss of control.
