## Probable cause

BLOCKAGE OF THE FUEL INJECTOR SERVO SYSTEM. FACTORS CONTRIBUTING TO THE ACCIDENT WERE: FUEL INJECTION SYSTEM CORRODED AND ANIMALS IN THE LANDING AREA.

## 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 - normal
  - fuel system,fuel control - blocked(total) (cause)
  - fuel injection control/system - corroded (contributing factor)
- Forced landing, descent - emergency
- On ground/water collision with object, landing - roll
  - object - animal(s) (contributing factor)

## Analysis

SHORTLY AFTER REACHING A CRUISE ALTITUDE OF 1500 FEET MSL THE AIRCRAFT'S ENGINE BEGAN RUNNING ROUGH WITH A CONCURRENT LOSS OF POWER. THE PILOT MANEUVERED THE AIRCRAFT NORTH FROM HIS OVERWATER POSITION TO A NEARBY FIELD CONTAINING APPROXIMATELY 60 GRAZING CATTLE AND EXECUTED A FORCED LANDING. DURING THE LANDING ROLL THE AIRCRAFT COLLIDED WITH SEVERAL COWS. DISASSEMBLY AND TESTING OF THE FUEL INJECTOR SERVO REVEALED EXTENSIVE INTERNAL CORROSION. ADDITIONALLY, A SMALL PIECE OF CORROSION MATERIAL WAS FOUND TO BE BLOCKING A FUEL METERING ORIFICE WITHIN THE FUEL INJECTOR SERVO.

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.
