What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
Aircraft landed in a field near airport after aircraft engine lost power and aircraft overshot runway, landing. (.4)the pilot was conducting a post-maintenance check flight of the aircraft following an annual inspection completed the prior day. During repairs associated with the annual inspection, the three engine control cables were replaced. While in cruise flight the engine lost power and the pilot attempted to glide to an emergency landing. He overshot the 3,100-foot-long runway and went off the departure end. When the engine was uncowled, the bolt which connects the throttle control to the throttle body actuator arm was missing. The bolt was found in the bottom of the cowling, but the nut was not located. The bolt did not comply with an applicable airworthiness directive. The pilot opined that after the throttle control separated, the engine may not have gone completely to the idle power position and the resulting partial engine power may have contributed to the landing overshoot. The pilot stated that he was wearing a headset and could not hear the engine w ell enough to detect a partial power condition.
As the FAA filed it
AIRCRAFT LANDED IN A FIELD NEAR AIRPORT AFTER AIRCRAFT ENGINE LOST POWER AND AIRCRAFT OVERSHOT RUNWAY, LANDING. (.4)THE PILOT WAS CONDUCTING A POST-MAINTENANCE CHECK FLIGHT OF THE AIRCRAFT FOLLOWING AN ANNUAL INSPECTION COMPLETED THE PRIOR DAY. DURING REPAIRS ASSOCIATED WITH THE ANNUAL INSPECTION, THE THREE ENGINE CONTROL CABLES WERE REPLACED. WHILE IN CRUISE FLIGHT THE ENGINE LOST POWER AND THE PILOT ATTEMPTED TO GLIDE TO AN EMERGENCY LANDING. HE OVERSHOT THE 3,100-FOOT-LONG RUNWAY AND WENT OFF THE DEPARTURE END. WHEN THE ENGINE WAS UNCOWLED, THE BOLT WHICH CONNECTS THE THROTTLE CONTROL TO THE THROTTLE BODY ACTUATOR ARM WAS MISSING. THE BOLT WAS FOUND IN THE BOTTOM OF THE COWLING, BUT THE NUT WAS NOT LOCATED. THE BOLT DID NOT COMPLY WITH AN APPLICABLE AIRWORTHINESS DIRECTIVE. THE PILOT OPINED THAT AFTER THE THROTTLE CONTROL SEPARATED, THE ENGINE MAY NOT HAVE GONE COMPLETELY TO THE IDLE POWER POSITION AND THE RESULTING PARTIAL ENGINE POWER MAY HAVE CONTRIBUTED TO THE LANDING OVERSHOOT. THE PILOT STATED THAT HE WAS WEARING A HEADSET AND COULD NOT HEAR THE ENGINE W ELL ENOUGH TO DETECT A PARTIAL POWER CONDITION.
