## Probable cause

THE PILOT'S FAILURE TO USE THE FUEL BOOST PUMP WHEN THE ENGINE MALFUNCTIONED DURING TAKE OFF.

## Sequence of events

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

- Loss of engine power(total) - nonmechanical, takeoff - initial climb
  - fluid,fuel - starvation
  - emergency procedure - not followed, pilot in command (cause)
  - fuel boost pump selector position - not corrected, pilot in command (cause)
- Forced landing, descent - emergency
- In flight collision with terrain/water, descent - emergency

## Analysis

AFTER TAKE OFF, AT ABOUT 300 FEET AGL, THE ENGINE BEGAN TO SPUTTER & LOSE POWER, ACCORDING TO THE PILOT. HE LANDED THE AIRPLANE IN A FIELD WHERE IT COLLIDED WITH BRUSH & THE GROUND. EXAMINATION OF THE AIRPLANE REVEALED THAT THERE WAS FUEL BETWEEN THE BOOST PUMP & THE FUEL INJECTOR SERVO, BUT NO FUEL BETWEEN THE SERVO & THE FUEL DISTRIBUTOR MANIFOLD. THE FUEL BOOST PUMP WAS EXAMINED & FOUND TO BE OPERATIONAL, AS WAS THE IGNITION SYSTEM. THE EMERGENCY PROCEDURE IN THE PILOT'S OPERATING HANDBOOK FOR THE AIRPLANE STATED THAT THE BOOST PUMP SHOULD BE TURNED ON IN THE EVENT OF AN ENGINE MALFUNCTION DURING TAKE OFF.

## 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 19921018042309A](https://openairdocs.org/incident/19921018042309A), Oct 18, 1992: Beech A23A, Cumming, GA, Substantial damage. Engine quit on climbout. Fuel interrupted from fuel servo. Condition could have been remedied by using boost pump.

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.
