Aircraft Accident/Incident Report
Hinckley, Illinois 60520
Monday, August 19, 1996 13:00 CDT
NTSB Narrative Summary Released at Completion of Accident
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.
NTSB Probable Cause Narrative
the instructor pilot exceeded the design stress limits of the aircraft which resulted in the overload failure of the wing. A factor was that the weight and balance of the aircraft was exceeded by the instructor pilot.
