NTSB narrative
The student had performed four full-stop landings then departed to remain in the traffic pattern. The student performed a low pass and at the mid point of the runway, he pitched up to climb, removed carburetor heat, applied full throttle, and 'removed one notch to flaps (to the 30-degree level).' He pitched for best climb but 'we started to lose altitude.' He verified the carburetor heat was off and the throttle was forward, and noted that the airspeed was at or just above 60 mph. He retracted the flaps to 20 degrees, 'but this did not seem to help.' He advised the CFI to take control of the airplane, the CFI rechecked the position of the carburetor heat and throttle, and recognizing that the flight could not return to the runway, maneuvered the airplane to a clearing. While descending the airplane collided with a power line, a fence, then the ground. Postaccident examination revealed sufficient fuel and no contaminants. Postaccident examination of the engine by the operator revealed no preimpact mechanical failure or malfunction. Review of the airplane pilot's operating handbook revealed that when performing a balked landing, reduce the flaps to 20 degrees immediately after full power is applied.
Probable cause
The inadequate supervision of the student pilot by the CFI for his failure to note that the student was performing a go-around from a low pass with 30-degree of flaps extended instead of the POH recommended 20-degrees. A factor in the accident was the failure of the student to retract the flaps from 40 degrees to 20 degrees during the go-around from a low pass.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
