NTSB narrative
WHILE ON A VFR CROSS COUNTRY FLIGHT, THE LEFT PROPELLER CONTROL RING FAILED AND THE LEFT PROPELLER COULD NOT BE FEATHERED. THE PILOT SHUT DOWN THE ENGINE DUE TO VIBRATION, DECLARED AN EMERGENCY, AND WAS VECTORED TO THE NEAREST AIRPORT. UNABLE TO MAKE IT TO THE RUNWAY, THE PILOT MADE A FORCED LANDING SHORT OF THE RUNWAY ON UNSUITABLE TERRAIN AND THE RIGHT MAIN LANDING GEAR COLLAPSED DURING LANDING ROLL.
Probable cause
A PROPELLER CONTROL UNIT FAILURE, AND LOSS OF THE PILOT'S OPTION TO FEATHER THE PROPELLER. A FACTOR WAS THE LACK OF SUITABLE TERRAIN FOR A FORCED LANDING.

- 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.
