NTSB narrative
WITNESSES RPTD THEY HEARD PROPELLER OVERSPEED FOLLOWED BY ENGINE PWR BEING REDUCED TO IDLE AS IF PILOT PULLED THROTTLE CLOSED. ACFT THEN BANKED TO LEFT AND ENTERED SPIN TO THE LEFT CRASHING INTO A PARKING LOT. POST CRASH EXAMINATION OF THE ENGINE, ACFT STRUCTURE, AND FLIGHT CONTROLS REVEALED NO EVIDENCE OF PRECRASH FAILURE OR MALFUNCTION. EXAMINATION OF THE PROPELLER REVEALED THE NUMBER TWO BLADE PITCH CHANGE ACTUATING PIN HAD FAILED DUE TO FATIGUE. THE PIN HAD BEEN INSTALLED AT OVERHAUL, 600 FLT HOURS BEFORE THE ACCIDENT, BY FOLLOWING MCCAULEY SERVICE BULLETIN 99 WHICH IS NOT APPLICABLE TO THIS MODEL PROPELLER. THE PIN WAS INSTALLED BY USING A SHORT THREADED PIN, A THIN SPACER, AND A BLIND HOLE IN THE FERRULE. THIS COMBINATION ALLOWED THE PIN TO BOTTOM OUT IN THE HOLE THUS NOT TORQUING PROPERLY AND THUS CRACKING DUE TO APPLIED LOADS.
Probable cause
THE PILOT-IN-COMMAND'S FAILURE TO MAINTAIN AIRSPEED, WHILE RETURNING FOR AN EMERGENCY LANDING FOLLOWING PROPELLER FAILURE, RESULTING IN THE AIRCRAFT STALLING AND ENTERING A SPIN.

- 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. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 1991-03-10.
