## Probable cause

FAILURE OF THE ENGINE-DRIVEN FUEL PUMP.  A FACTOR WAS THE PILOT'S FAILURE TO SELECT THE AUXILIARY FUEL PUMP.

## Sequence of events

In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf).

- Loss of engine power(total) - mech failure/malf, cruise
  - fuel system,pump - deteriorated (cause)
  - fuel boost pump selector position - not selected, pilot in command (contributing factor)
  - fluid,fuel - starvation
- Forced landing, descent - emergency
  - terrain condition - none suitable
- In flight collision with object, descent - emergency
  - object - wire,transmission
- In flight collision with terrain/water, descent - uncontrolled

## Analysis

THE AIRPLANE'S ENGINE LOST POWER DURING CRUISE AT 2000 FEET AGL.  THE PILOT MANEUVERED TO A HIGHWAY, SAW TRAFFIC AND TURNED TO A FIELD.  ON FINAL THE PILOT SAW A POWER LINE AND ASSESSED HE COULD NOT MANEUVER TO AVOID.  DISASSEMBLY OF THE MECHANICAL FUEL PUMP SHOWED A SPLIT SEAL ON A DIAPHRAGM SHAFT.  THE PILOT DID NOT RECALL SELECTING THE AUXILIARY PUMP AFTER ONSET OF THE POWER LOSS.

## FAA reports on this event (1)

The FAA's own accident and incident reports, matched to the aircraft by N-number and date (OpenAirDocs).

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
