Salt Lake City Intl Airport
Aircraft Accident/Incident Report

Salt Lake City, Utah 84116
Sunday, March 31, 1996 17:30 MST

NTSB Narrative Summary Released at Completion of Accident

The pilot reported that during the takeoff ground roll, a loud 'boom' was heard, and the right engine lost power. The pilot aborted the takeoff and immediately brought the thrust lever to idle power. He stated that as the airplane was turning off of the runway onto a taxiway, the right engine 'blew.' The pilot continued to taxi the airplane back to the fixed base operator. After the airplane was secured, the pilot inspected the right engine and found evidence of an uncontained engine failure. Debris from the right engine had punctured the side of the pressure vessel and damaged the wing. Further inspection revealed the engine impeller had broken into two large pieces. A metallurgical examination of the impeller determined that a fatigue crack had originated from the aft face in the area containing a circumferential groove mark that was produced during machining of the aft face prior to blue etch anodizing.

NTSB Probable Cause Narrative

fatigue failure of the engine compressor impeller. Inadequate quality control by the manufacturer was a related factor.
