1990-10-28 · PARKERSBURG, West Virginia, United States · None · 1 aircraft · Status: Completed
N52DC has since been reassigned. It is now registered to a different aircraft (RANS S-21 OUTBOUND, built 2023), which was not involved in this event.
Aircraft involved
Probable cause & findings
CATASTROPHIC FAILURE OF THE LEFT ENGINE FAN DISC DUE TO LOW CYCLE FATIGUE.
Factual narrative
N52DC WAS CLIMBING THRU FL280 WHEN THE FLT CREW FELT A 'VIOLENT SHUDDER' IN THE AIRFRAME AND OBSERVED INDICATIONS OF A LEFT ENGINE FAILURE. VISUAL EXAMINATION OF THE LEFT ENG REVEALED THE FAN SECTION HAD SEPARATED (UNCONTAINED FAILURE/TEARAWAY). THE AIRPLANE WAS LANDED WITHOUT FURTHER INCIDENT. A POST-ACCIDENT EXAM OF THE PARTS REVEALED THE FAN DISC FAILED CATASTROPHICALLY DUE TO LOW CYCLE FATIGUE. Source: NTSB Aviation Accident Database (Pre-2008 Archive) Retrieved: 2026-02-12
