## Probable cause

THE FAILURE OF AN ENGINE CYLINDER HEAD. COLLISION WITH A LOG DURING THE LANDING WAS A FACTOR RELATED TO THE ACCIDENT.

## Sequence of events

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

- Loss of engine power(total) - mech failure/malf, climb
  - engine assembly,cylinder - failure,total (cause)
- Forced landing, landing
  - terrain condition - none suitable
- On ground/water collision with object, landing - roll
  - object - other (contributing factor)

DURING INITIAL CLIMB AFTER TAKEOFF, THE NUMBER 2 CYLINDER HEAD FAILED FORCING THE PILOT TO LAND GEAR UP ON A SANDY BEACH. DURING THE LANDING, THE AIRCRAFT HIT A LOG, CAUSING SUBSTANTIAL DAMAGE TO THE AIRCRAFT.
