Fatal 2019 DC-3 Turbo Prop Accident, Positioning for FAA Flight Test: Power Loss Plus Failure to Feather
NTSB suggest an air lock in the fuel system plus an auto-feather system failure which may have occurred if the power lever was manually retarded during the auto-feather sequence. The DC-3 was below the airspeed required to maintain lateral control after an engine failure with an unfeathered propeller.
ATR 72 Rudder Travel Limitation Unit Incident: Latent Potential for Misassembly Meets Commercial Pressure
An ATR72 suffered an uncommanded yaw and roll as it accelerated through 185 knots. The cause was traced to misassembly during a prior maintenance check. A cam in the rudder Travel Limitation Unit could be reversed, and pressures during the check triggered that misassembly.
BEA Point to Inadequate Maintenance Data and Possible Non-Conforming Fasteners in ATR 42 Door Loss
