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.

(.4) The airplane's engine started on the first attempt, and ran 'smoothly.' The pilot then taxied the airplane short of the runway, and completed the run-up checks. No anomalies were noted. He then taxied onto the runway, advanced the throttle, and scanned the engine instruments. No deficiencies were observed, so the pilot executed the takeoff. After retracting the flaps, and reaching about 500 feet AGL, the pilot executed a left turn to stay within glided distance of the airport. Approximately 30 degrees through the turn, the airplane experienced a loss in power. The propeller continued to windmill, but the engine did not responded to throttle movements. With insufficient altitude to reach the runway the pilot executed a forced landing to a field. Examination of the engine revealed that the inner liner of the air-intake had separated from the outer liner, blocking airflow to the fuel servo. (-23) aircraft departed mrb on runway 26 at approximately 500 feet. Engine quit. It had been running normal to that point, aircraft landing in field striking haybale which sheared right wing off aircraft.

As the FAA filed it

(.4) THE AIRPLANE'S ENGINE STARTED ON THE FIRST ATTEMPT, AND RAN 'SMOOTHLY.' THE PILOT THEN TAXIED THE AIRPLANE SHORT OF THE RUNWAY, AND COMPLETED THE RUN-UP CHECKS. NO ANOMALIES WERE NOTED. HE THEN TAXIED ONTO THE RUNWAY, ADVANCED THE THROTTLE, AND SCANNED THE ENGINE INSTRUMENTS. NO DEFICIENCIES WERE OBSERVED, SO THE PILOT EXECUTED THE TAKEOFF. AFTER RETRACTING THE FLAPS, AND REACHING ABOUT 500 FEET AGL, THE PILOT EXECUTED A LEFT TURN TO STAY WITHIN GLIDED DISTANCE OF THE AIRPORT. APPROXIMATELY 30 DEGREES THROUGH THE TURN, THE AIRPLANE EXPERIENCED A LOSS IN POWER. THE PROPELLER CONTINUED TO WINDMILL, BUT THE ENGINE DID NOT RESPONDED TO THROTTLE MOVEMENTS. WITH INSUFFICIENT ALTITUDE TO REACH THE RUNWAY THE PILOT EXECUTED A FORCED LANDING TO A FIELD. EXAMINATION OF THE ENGINE REVEALED THAT THE INNER LINER OF THE AIR-INTAKE HAD SEPARATED FROM THE OUTER LINER, BLOCKING AIRFLOW TO THE FUEL SERVO. (-23) AIRCRAFT DEPARTED MRB ON RUNWAY 26 AT APPROXIMATELY 500 FEET. ENGINE QUIT. IT HAD BEEN RUNNING NORMAL TO THAT POINT, AIRCRAFT LANDING IN FIELD STRIKING HAYBALE WHICH SHEARED RIGHT WING OFF AIRCRAFT.
