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.
Probable cause
A FAILED (CRACKED) ENGINE PLENUM RESULTING IN LOSS OF ENGINE POWER.

Source notes (4)
- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: local date, investigation status, damage. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 1989-03-21.
- API snapshot SHA-256: 20e98912fa706bead78d0cd7ef3438768c19943f4d3f9c089088e7f59e0e9136; retrieved 2026-09-18T19:13:18.601Z.
