## Probable cause

THE TOTAL LOSS OF ENGINE POWER FOR UNDETERMINED REASONS.

## Sequence of events

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

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

## Analysis

DURING A CLIMB TO CRUISE OVER TERRAIN IN A FLOAT EQUIPPED AIRPLANE, THE ENGINE LOST POWER. THE PILOT WAS UNABLE TO RESTART THE ENGINE AND INITIATED A FORCED LANDING IN A HEAVILY WOODED AREA. DURING A POST-CRASH INSPECTION OF THE ENGINE, THERE WERE NO NOTED MECHANICAL FAILURES OR MALFUNCTIONS.
