Read the full NTSB narrative
THE ACCIDENT AIRPLANE EXPERIENCED AN INFLIGHT FAILURE OF A PROPELLER BLADE DURING CRUISE FLIGHT. ACCORDING TO THE PILOT'S STATEMENT THE AIRPLANE STARTED A SEVERE VIBRATION AND REDUCING THE ENGINE POWER HAD NO EFFECT ON IT. THE VIBRATION STOPPED AFTER HE SHUT DOWN THE ENGINE AND RAISED THE NOSE IN ORDER TO STOP THE WINDMILLING PROPELLER. DURING THE FORCED LANDING THE LANDING GEAR COLLAPSED AND THE AIRPLANE SLID INTO A DIRT BANK. EXAMINATION OF THE REMAINING PORTION OF THE FAILED PROPELLER BLADE FRACTURE SURFACE SHOWED A FATIGUE CRACK EXTENDING FROM THE LEADING EDGE TO A POINT 3-1/4 INCHES MEASURED IN THE CHORDWISE DIRECTION. THE LEADING EDGE HAD BEEN REWORKED BY FILING OR GRINDING.
