## Probable cause

THE PILOT'S INABILITY TO AVOID UNSUITABLE TERRAIN DURING THE LANDING ROLL AFTER A FORCED LANDING. THE FORCED LANDING WAS MADE NECESSARY BY A LOSS OF ENGINE POWER CAUSED BY A FOREIGN OBJECT RESTRICTING THE FUEL SYSTEM.

## Sequence of events

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

- Loss of engine power(partial) - nonmechanical, takeoff - initial climb
  - fuel system,fuel quantity float/sensor - foreign object (cause)
  - maintenance,inspection - improper (cause)
- Forced landing, descent - emergency
- On ground/water collision with object, landing - roll
  - terrain condition - ditch (contributing factor)
  - terrain condition - none suitable (contributing factor)
- Nose over, landing - roll

## Analysis

JUST AFTER LIFTOFF, THE ACFT EXPERIENCED A PARTIAL LOSS OF ENGINE POWER & A FORCED LANDING WAS PERFORMED. THE ACFT TOUCHED DOWN ABOUT 300 FEET FROM THE DEPARTURE END OF THE RUNWAY, THEN COLLIDED WITH A DITCH AND NOSED OVER. POST ACCIDENT INVESTIGATION REVEALED SEVERAL SMALL MELTED BALLS OF SOLDER IN THE CARBURETOR, RESTRICTING THE FUEL FLOW. THE ENGINE HAD BEEN PREVIOUSLY INVOLVED IN A CARBURETOR INTAKE FIRE WHICH MAY HAVE CAUSED THE SOLDER TO MELT.
