A 6-bladed Hamilton Standard 568F propeller on an ATR 72 short-haul airliner. Lowry [27] quotes a propeller efficiency of about 73.5% at cruise for a Cessna 172.This is derived from his "Bootstrap approach" for analyzing the performance of light general aviation aircraft using fixed pitch or constant speed propellers.

The fire went out before the aircraft came to rest and all passengers and crew were evacuated. Five people had minor injuries, some from parts of the propeller entering the cabin and others from the evacuation. [citation needed]
