NTSB narrative
The pilot was in cruise flight in the single-engine airplane when the engine started to run rough. He applied carburetor heat, but the engine continued to run rough. He noticed that the fuel pressure gauge indicated 0, so he turned on the electric fuel boost pump, which did not restore power. He then switched fuel tanks, which momentarily restored engine power. The pilot decided to divert to a nearby airport and continued to switch between fuel tanks to obtain short bursts of engine power. During landing, the airplane departed the runway surface and the nose landing gear collapsed. Examination of the fuel system found available fuel in the tanks and only a small amount of debris in the gascolator. Both the engine-driven and electric fuel boost pumps were removed from the airplane. Hand testing of the engine-driven pump found suction and pressure at the inlet and outlet ports. Testing of the electric boost pump revealed that liquid would not flow when activated. Despite the failure of the electric boost pump, it was not indicated for use in cruise flight, and its failure should not have resulted in a loss of fuel flow. It is possible that an unidentified fuel restriction prevented fuel from getting to the engine-driven fuel pump; however, the reason for or source of the fuel restriction could not be determined during postaccident examination.
Probable cause
A partial loss of engine power due to a restriction in fuel flow for undetermined reasons.

- 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, coordinates. 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.
