NTSB narrative
WHILE CLIMBING THROUGH ABOUT 6500 FT, A LOUD BANG WAS HEARD AND THE PILOT SAW THE ENGINE COWLING BUCKLE. ABOUT 10 SECONDS LATER, THE ENGINE CEASED TO OPERATE. THE PILOT DECLARED AN EMERGENCY AND LANDED ON AN UNCONTROLLED AIRPORT. AFTER LANDING, AN EXAMINATION OF THE AIRCRAFT REVEALED THAT THE PROPELLER HAD SEPARATED AND THERE WAS SUBSTANTIAL DAMAGE FROM OBVIOUS ENGINE VIBRATION. THE PROPELLER ASSEMBLY WAS FOUND ON A HIGHWAY WITH ONE BLADE MISSING. A METALLURGICAL EXAMINATION REVEALED THAT THE BLADE HAD SEPARATED AFTER THE PROPELLER HUB, MCCAULEY PN TCP3EA-PC3, HAD FAILED FROM FATIGUE.

- 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: investigation status. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
