From the FAA’s Accident/Incident Data System (AIDS), through its Aviation Safety Information Portal, as reported. The NTSB investigates accidents separately, and its record of an accident is the fuller one. The aircraft is matched to the registry by N-number and event date, checked against the reported make and model; the registry’s history has gaps, so older matches can be wrong. Compare the reported make and model.

What happened

The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.

(-23) Shortly after takeoff from sez, a counterweight bolt on the ham-std, 3D40-271 prop broke, allowing one blade to go to full course pitch while remaining two blades remained at flat pitch, causing a severe vibration and loss of thrust. Pilot turned back to the airport and was able to make the runway. The aircraft contacted the runway with the gear still in transit causing the aircraft to bounce back into the air. It also caused a serve to the right. With the bounce, the gear did lock down and was able to keep it straight and the tail down, but lacking thrust, pilot could not regain the runway. Aircraft went off crossed the taxi way, continuing on the ground, striking a tree and post doing damage to the leading edges and tips of both of the wings. Pilot shut down the engine and secured the aircraft.

As the FAA filed it

(-23) SHORTLY AFTER TAKEOFF FROM SEZ, A COUNTERWEIGHT BOLT ON THE HAM-STD, 3D40-271 PROP BROKE, ALLOWING ONE BLADE TO GO TO FULL COURSE PITCH WHILE REMAINING TWO BLADES REMAINED AT FLAT PITCH, CAUSING A SEVERE VIBRATION AND LOSS OF THRUST. PILOT TURNED BACK TO THE AIRPORT AND WAS ABLE TO MAKE THE RUNWAY. THE AIRCRAFT CONTACTED THE RUNWAY WITH THE GEAR STILL IN TRANSIT CAUSING THE AIRCRAFT TO BOUNCE BACK INTO THE AIR. IT ALSO CAUSED A SERVE TO THE RIGHT. WITH THE BOUNCE, THE GEAR DID LOCK DOWN AND WAS ABLE TO KEEP IT STRAIGHT AND THE TAIL DOWN, BUT LACKING THRUST, PILOT COULD NOT REGAIN THE RUNWAY. AIRCRAFT WENT OFF CROSSED THE TAXI WAY, CONTINUING ON THE GROUND, STRIKING A TREE AND POST DOING DAMAGE TO THE LEADING EDGES AND TIPS OF BOTH OF THE WINGS. PILOT SHUT DOWN THE ENGINE AND SECURED THE AIRCRAFT.
