Core lock information


Core lock is a turbine engine failure that can happen to aircraft in flight. When an engine is shut down in flight, the design of the engine causes some parts to cool quicker than others. Since materials change sizes in different temperatures, this happens to the turbine engine. Core lock happens if the engine's parts change too much in size, then some parts will get stuck, reducing or even stopping rotation.

Core lock makes it difficult for pilots to perform either a windmill restart or an APU-assisted engine restart.

When the engine parts’ temperature is allowed to normalize, after time is given, the parts will normalize in sizes, removing the core lock condition.
