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.

On local flight, normal pattern work, went into a spin. Right wing collapsed, aircraft hit the ground. (.4)the engine tach indicated that the instructor pilot and student pilot had operated the airplane for about 5 minutes before it crashed about 1/2 mile south of the departure end of the runway. A witness reported he saw the airplane already established in a left spiral at 500 to 700 feet AGL, in about a 70-degree nose-down attitude. He reported the wings were intact as it spiraled very fast before the right wing separated straight back from the aircraft. The examination of the right wing strut attach fitting indicated it failed as a result of overstressing loads. The examination of the fore and aft wood spars indicated they had failed as a result of overload forces. The examination of the inboard rear strut attach fitting indicated it had failed in tension overload. The aircraft was 94 pounds over the maximum gross weight. (-23) aircraft departed hinkley airport for local flight. Aircraft observedin a spin. Aircraft right wing came off aircraft, aircraft hit ground.
