Read the full NTSB narrative
WHILE CLIMBING AFTER TAKEOFF AT NIGHT, THE RIGHT ENGINE FAILED. THE FIGHT CREW SECURED THE RIGHT ENGINE & RETURNED TO A SAFE LANDING AT THE AIRPORT. AN ENGINE INSPECTION REVEALED A CRACK IN THE PLENUM COMBUSTOR CHAMBER. THE CRACK EMINATED FROM A WELD BETWEEN TWO EXTERNALLY FIXED (WELDED) MOUNTS. THIS WAS THE SECOND PLENUM CHAMBER USED ON THIS ENGINE IN SIX MONTHS AND WAS OBTAINED FROM SPARE PARTS OF ANOTHER AIRCRAFT. IT WAS VISUALLY DETERMINED TO BE AIRWORTHY. NO OPERATIONAL HISTORY WAS AVAILABLE ON THIS PLENUM, NOR WAS THERE A SPECIFIC REQUIREMENT. REPLACEMENT WAS ON CONDITION, AND DAMAGE CONDITIONS WERE REQUIRED TO MEET THE MANUFACTURERS CRITERIA.
