NTSB narrative
THE PILOT MADE A TAKEOFF WITH THE FLAPS SET AT 30 DEGREES, ON AN UPHILL RUNWAY INTO THE WIND. THE AIRPLANE WAS LOADED AT OR NEAR ITS GROSS WEIGHT. THERE WAS RISING TERRAIN OFF THE DEPARTURE END OF THE RUNWAY WHICH EXCEEDED THE ABILITY OF THE AIRPLANE TO CLIMB. THE AIRPLANE STALLED AND STRUCK THE GROUND. POST ACCIDENT INVESTIGATION DISCLOSED THE WING FLAPS WERE AT 35 DEGREES AND THE PILOT WHEN INTERVIEWED SAID THERE WAS NO PROBLEM WITH THE ENGINE. HE SAID HE USED THE 30 DEGREE FLAP SETTING TO GET AIRBORNE FASTER. IN THE CESSNA 172M OWNER'S MANUAL, FLAP SETTINGS GREATER THAN 10 DEGREES ARE NOT RECOMMENDED FOR TAKEOFF.
Probable cause
AN INADVERTENT STALL AND LOSS OF CONTROL DUE TO THE PILOT'S IMPROPER USE OF THE WING FLAPS FOR TAKEOFF. FACTORS RELATED TO THE ACCIDENT WERE: THE PILOT'S MISUNDERSTANDING OF AIRPLANE PERFORMANCE, AND THE PILOT'S DECISION TO TAKEOFF UPHILL.

- 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.
