AAIB Report: Turbine Blade Fatigue Caused DHL Boeing 767 Engine Failure at Heathrow
A DHL Air UK Boeing 767-300F experienced a significant left engine failure during its takeoff roll at London Heathrow Airport. The flight crew successfully performed a high-speed rejected takeoff, bringing the aircraft to a safe stop on the runway. The UK's Air Accidents Investigation Branch (AAIB) determined the event was caused by a fatigue crack in a 3rd stage high-pressure turbine blade. This resulted in an uncontained failure, with debris exiting the engine casing. Following the incident, regulators issued a mandatory Airworthiness Directive for inspections that were previously recommended by the engine manufacturer in a non-mandatory bulletin.
