The NTSB's narrative final · quoted from the NTSB record

The instructor reported that the flight took off with approximately 1/2 fuel; the student stated that the flight then proceeded normally for 45 minutes to an hour prior to the accident. Both pilots reported that after applying full power on a touch-and-go and departing the runway, the aircraft did not climb at an acceptable rate (although the student reported that 'The engine seemed to be running smoothly but without power.') The aircraft's stall warning activated and the instructor took control, but he was unable to arrest a 'shallow descent' despite applying full power. The aircraft crashed about 200 yards west of the end of the airstrip's runway. Available data did not support a lack of aircraft climb capability for the density altitude conditions, excess aircraft gross weight, or a significant carburetor icing hazard. The student's carbon monoxide (CO) level was found to be slightly elevated after the accident, but the instructor's CO level was normal. Post-accident examinations of the aircraft's engine and exhaust system did not reveal any evidence of pre-accident defects.
