  - fuel system,pump - failure,partial (contributing factor)
  - remedial action - not understood, pilot in command (cause)
  - lack of familiarity with aircraft, pilot in command

- Forced landing, descent - emergency
- On ground/water encounter with terrain/water, landing - flare/touchdown
  - terrain condition - rough/uneven (contributing factor)

## Analysis

THE PLT STATED THAT HE WAS RETURNING TO THE ARPT AND WAS ON THE BASE LEG OF THE TRAFFIC PATTERN WHEN HE EXPERIENCED A PARTIAL LOSS OF ENG PWR. THE PLT STATED THAT WHEN HE TURNED ON THE BOOST PUMP, PWR WAS RESTORED FOR A SHORT TIME. HE CONTINUED TO STATE THAT HE COULD NOT RESTORE SUFFICIENT PWR TO MAINTAIN FLT. AN EMERGENCY LANDING WAS EXECUTED IN AN OPEN FIELD. POST CRASH EXAM OF THE ENG REVEALED NO EVIDENCE OF A MECHANICAL MALFUNCTION OR FAILURE. THE PLT HAS 2.5 HOURS OF FLT TIME IN THIS MAKE AND MODEL ACFT. THE PLT STATED THAT HE MANAGED TO GET THE ENG STARTED ON BASE LEG AFTER THE INITIAL PWR LOSS BY USING THE FUEL BOOST PUMP. HE STATED THAT AFTER THE ENG STARTED HE FLIPPED THE BOOST PUMP SWITCH OFF AND THE ENG IMMEDIATELY LOST PWR AGAIN. THE PLTS HANDBOOK (FLT MANUAL) STATES THAT THE PUMP SHOULD BE ON FOR AN AIR START &  LEFT ON IF THE FUEL PUMP IS SUSPECTED OF FAILURE LOSS OF FUEL PRESSURE WITH BOOST PUMP OFF. THE PLT INDICATED THE START PROCESS WAS REPEATED SEVERAL TIMES WITH SIMILIAR RESULTS.

## FAA reports on this event (1)

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

- [Accident 19850301005249A](https://openairdocs.org/incident/19850301005249A), Mar 1, 1985: Beech E33C, Richfield, UT, Substantial damage. Engine lost power on base leg. Engine driven fuel pump failed. Improper use of electric pump. Landed in a field.

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.
