## Probable cause

LOSS OF ENGINE POWER FOR UNDETERMINED REASONS. THE LACK OF SUITABLE TERRAIN FOR A FORCED LANDING WAS A FACTOR.

## Sequence of events

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

- Loss of engine power, takeoff - initial climb
  - reason for occurrence undetermined (cause)
- Forced landing, descent - emergency
- In flight collision with terrain/water, descent - emergency
  - terrain condition - water
  - terrain condition - none suitable (contributing factor)

## Analysis

THE COMMERCIAL PILOT STATED THAT EARLIER IN THE MORNING HE HAD CONDUCTED A PRECAUTIONARY LANDING IN AN OPEN FIELD DUE TO A ROUGH RUNNING ENGINE. FIVE SPARK PLUGS WERE CHANGED AND AN ENGINE RUN UP WAS CONDUCTED WITH NO DEFICIENCIES NOTED. THE PILOT TOOK OFF FROM THE OPEN FIELD AND REACHED AN ALTITUDE BETWEEN 200 TO 300 FEET AGL WHEN THE AIRPLANE EXPERIENCED A LOSS OF ENGINE POWER. THE PILOT CONDUCTED A FORCED LANDING INTO A POND TO AVOID HOUSES AND GROUND PERSONNEL. AN ON-SCENE EXAMINATION CONDUCTED BY THE FAA REVEALED NO EVIDENCE TO INDICATE ANY PREIMPACT FAILURE OR MALFUNCTION. THE FAA INSPECTOR WROTE IN A STATEMENT TO THE NTSB INVESTIGATOR-IN-CHARGE, THAT AFTER A THOROUGH INVESTIGATION, INCLUDING AN INTERVIEW WITH THE PILOT, THE EXACT CAUSE OF THE ACCIDENT COULD NOT BE DETERMINED.
