Boeing 747-132, over Lake Michigan, Oct. 20, 2004–The Safety Board attributed the separation of the cargo 747’s number-one engine from its mounts to the uncontained separation of a portion of the second-stage turbine disk rim after the second-stage turbine vanes contacted the disk, due to the operator’s inadequate inspection of the high-pressure turbine module and the improper repair of the module. The Kalitta Air flight was climbing through 15,000 feet over Lake Michigan when the problem developed. The crew diverted to Detroit Metropolitan Wayne County Airport and landed without incident.
Final Report: Engine separated from Boeing 747
