## 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, takeoff - initial climb
  - fuel system - incorrect (contributing factor)
  - fuel boost pump selector position - inadvertent use, pilot in command (cause)
  - acft/equip,inadequate control location, manufacturer (contributing factor)
- Forced landing, takeoff - initial climb
  - light condition - daylight
- Hard landing, landing - flare/touchdown
  - airport facilities,runway/landing area condition - rough/uneven
  - stall - inadvertent, pilot in command (contributing factor)

## Analysis

SHORTLY AFTER TAKEOFF, THE PLT OF THE BEECH A36TC ACFT ACTIVATED WHAT HE BELIEVED WAS THE FLAP RETRACTION LEVER, AND THE ENG QUIT. THE PLT MADE A FORCED LANDING APRX 1000 FT FROM THE RWY DEPARTURE END. DURING THE INVESTIGATION, THE ENG WAS STARTED AND FUNCTIONED NORMALLY, UNTIL THE EMERG FUEL PUMP (EFP) SWITCH WAS ACTIVATED, WHICH RESULTED IN THE ENG QUITTING DUE TO FLOODING. THIS STEP WAS REPEATED SEVERAL TIMES WITH THE SAME RESULTS. THE EFP SWITCH AND FLAP RETRACTION LEVER ARE APRX TWO INCHES APART.

## 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 19851101055729A](https://openairdocs.org/incident/19851101055729A), Nov 1, 1985: Beech A36TC, Bismarck, ND, Substantial damage. Mistakenly turned on emergency fuel pump instead of moving flap lever. The engine quit. Impacted on rolling terrain

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.
