NTSB narrative
The pilot reported that during the initial climb, about 2,000 feet above the ground, he switched to the auxiliary fuel tank and the engine lost power. He applied full throttle and mixture, as well as established a glideslope to return to the airport. The airplane descended faster than the pilot expected and impacted terrain short of the runway. A postaccident examination of the airframe and engine revealed no evidence of mechanical malfunctions or failures that would have precluded normal operation. The right, left, and auxiliary fuel tanks were all about a quarter full. The airplane flight manual states that the fuel selector valve should be on the main tank containing the most fuel during takeoff and landing. The auxiliary tank should only be used in level flight. During a climb, with the auxiliary fuel tank about one-quarter full, it is likely that fuel within the tank was insufficient to exit the tank through the fuel feed and therefore starved the engine of fuel.
Probable cause
The pilot’s improper fuel management, which resulted in a loss of engine power during climb due to fuel starvation.

- 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.
