Narrative:
A Cessna 500 Citation, N727TK, experienced an uncontained engine failure during the take off ground roll at the Salt Lake City International Airport, Utah, USA. Visual meteorological conditions prevailed at the time and an instrument flight rules flight plan was filed. The airplane was substantially damaged, and the private and commercial pilots, and their five passengers were not injured. The flight was destined for Visalia, California.
The engine start and all pre-take off checks were completed with no abnormalities noted. The airplane was taxied to runway 35 and held for approximately ten minutes before the tower controller cleared the flight for take off. After advancing the thrust levers through 80-81%, a loud "boom" was heard and the airplane began to shake. The thrust lever for the right engine was brought back to idle power and the pilot continued to taxi back to the apron.
It was noted that debris from the engine had punctured the side of the pressure vessel and damaged the wing.
Fatigue failure of the engine compressor impeller. Inadequate quality control by the manufacturer was a related factor.
