## Probable cause

AN IMPROPER DECISION DURING FLIGHT WHEN THE PILOT IN COMMAND OVERFLEW TWO SUITABLE LANDING AREAS AFTER A PARTIAL POWER LOSS IN ONE ENGINE. THE MECHANICAL DEFICIENCIES IN THE ENGINES WERE FACTORS IN THE ENGINE.

## Sequence of events

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

- Loss of engine power(partial) - mech failure/malf, cruise - normal
  - 1 engine
  - ignition system,magneto - failure,partial (contributing factor)
  - in-flight planning/decision - improper, pilot in command (cause)
  - precautionary landing - not performed, pilot in command (cause)
- Loss of engine power(total) - mech failure/malf, cruise - normal
  - 1 engine
  - fuel injection control/system - failure,total (contributing factor)
- Forced landing, descent - uncontrolled
- On ground/water collision with object, landing - roll
  - terrain condition - hidden obstruction(s)

## Analysis

THE ACCIDENT AIRPLANE COLLIDED WITH A DITCH DURING A FORCED LANDING.  THE LANDING OCCURRED AFTER THE AIRPLANE SUSTAINED A PARTIAL LOSS OF POWER IN THE RIGHT ENGINE, FOLLOWED BY A TOTAL LOSS OF POWER IN THE LEFT ENGINE. THE UNREGISTERED AIRPLANE WAS BEING OPERATED AS A FERRY FLIGHT.  THE PILOT STATED THAT THE RIGHT ENGINE BEGAN RUNNING ROUGH ABOUT 15 MINUTES INTO THE FLIGHT.  ABOUT 15 MINUTES LATER THE LEFT ENGINE STOPPED.  HE ATTEMPTED A RESTART AND WAS NOT SUCCESSFUL.  HE REPORTED HE COULD NOT MAINTAIN ALTITUDE AND SELECTED A ROAD FOR LANDING.  WHEN HE OBSERVED VEHICLES ON THE ROAD HE SELECTED AND ULTIMATELY LANDED IN A WHEAT FIELD.  THE AIRPLANE STRUCK THE DITCH DURING THE LANDING ROLL. AFTER ACCIDENT INSPECTION OF THE AIRPLANE SHOWED A DEFECTIVE RIGHT MAGNETO ON THE RIGHT ENGINE.  A DEFECTIVE DIAPHRAGM WAS DISCOVERED IN THE LEFT ENGINE THROTTLE BODY.  A MAP REVIEW SHOWS THE PILOT OVERFLEW TWO SUITABLE AIRPORTS AFTER THE RIGHT ENGINE BEGAN RUNNING ROUGH.
