## Probable cause

AN ENGINE FAILURE CAUSED BY A SEIZED PISTON.  A FACTOR ASSOCIATED WITH THE ACCIDENT IS THE FAILURE OF THE PILOT TO MAINTAIN A PROPER DESCENT RATE DURING HIS FORCED LANDING.

## Sequence of events

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

- Loss of engine power, climb
  - engine assembly,piston - seized (cause)
- Forced landing, descent - emergency
- Loss of control - in flight, maneuvering - turn to reverse direction
  - proper descent rate - not maintained, pilot in command (contributing factor)
- In flight collision with terrain/water, descent - uncontrolled

## Analysis

THE ACCIDENT AIRPLANE LANDED HARD AFTER AN ENGINE FAILURE AT ALTITUDE. THE AIRPLANE CAUGHT FIRE AFTER IMPACT.  ENGINE DISASSEMBLY REVEALED A SEIZED PISTON IN NUMBER 1 CYLINDER.
