## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

(-23) SHORTLY AFTER TAKE OFF, THE PILOT NOTICED THE PROPELLER HAD GONE TOO HIGH SPEED AND HE COULD NOT CONTROL IT. HE DECIDED TO TURN AROUND AND LAND BACK AT THE AIRPORT. SHORTLY AFTER TURNING AROUND, THE ENGINE SUDDENLY LOST POWER. THE PILOT COULD NOT MAKE IT TO THE RUNWAY SO HE WAS FORCED TO LAND IN A HAY FIELD. THE AIRCRAFT WAS DESTROYED DURING THE LANDING. POST CRASH INVESTIGATION REVEALED THE ENGINE QUIT DUE TO THE LOSS OF ENGINE OIL. A LARGE SPOT OF OIL WAS FOUND ON THE GROUND IN THE AREA WHERE THE PILOT HAD PERFORMED HIS PRE-TAKEOFF RUNUP. DURING THE EXAMINATION OF THE ENGINE, THE INVESTIGATION TEAM FOUND THAT AN ACCESSORY DRIVE ADAPTER GASKET HAD BEEN PUSHED OUTWARD, ALLOWING ENGINE OIL TO BE PUMPED OUT OF THE CRANK CASE WHILE THE ENGINE WAS RUNNING. THE ENGINE HAD ONLY BEEN OPERATED ABOUT 34 HOURS SINCE A NEW PROPELLER HAD BEEN INSTALLED. THE FAILED GASKET WAS THE WRONG GASKET FOR THE COVER THAT WAS INSTALLED ON THIS ENGINE.

## The NTSB's investigation of this event (1)

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
