## Probable cause

EXCESSIVE FUEL SYSTEM PUMP PRESSURE AND CORRESPONDING EXCESSIVE FUEL PRESSURE AND THE PILOT NOT MAINTAINING THE BEST SINGLE ENGINE CLIMB SPEED.

## 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, approach - vfr pattern - downwind
  - 1 engine (contributing factor)
  - fluid,fuel - pressure excessive (cause)
- Forced landing, approach - vfr pattern - downwind
  - emergency procedure - performed, pilot in command
  - airspeed(vyse) - not maintained, pilot in command (cause)
  - altitude - not maintained, pilot in command (contributing factor)
- In flight collision with terrain/water, descent - emergency
  - terrain condition - crop

## Analysis

THE TWIN ENGINE CARGO AIRPLANE WAS PREPARING TO ENTER A BASE LEG FOR LANDING WHEN THE LEFT ENGINE CEASED OPERATING. DURING THE TRANSITION TO SINGLE-ENGINE OPERATIONS, THE PILOT STATED THE AIRPLANE'S AIRSPEED WENT BELOW THE SINGLE ENGINE BEST RATE OF CLIMB AIRSPEED AND A DESCENT WAS ENTERED. THE PILOT STATED HE WAS NOT ABLE TO TURN ONTO BASE LEG BECAUSE WHEN HE ATTEMPTED TO DO SO THE AIRPLANE'S STALL WARNING SYSTEM WOULD ACTIVATE. THE PILOT STATED HE WAS NOT ABLE TO PITCH THE AIRPLANE'S ATTITUDE DOWN TO REGAIN AIRSPEED BECAUSE OF LOW ALTITUDE. THE PILOT ELECTED TO LAND IN A CORN FIELD. THE ON SCENE INVESTIGATION AND POST ACCIDENT TESTING REVEALED THE LEFT ENGINE'S FUEL PUMP WAS DEFECTIVE AND HAD FLOODED THE ENGINE.

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.
