## Probable cause

FAILURE OF THE NON FAA CERTIFICATED PILOT TO MAINTAIN AIRSPEED AND THE INADVERTENT STALL DURING AN ATTEMPTED PRECAUTIONARY LANDING FOLLOWING PARTIAL LOSS OF ENGINE POWER DUE TO UNDETERMINED REASONS.

## Sequence of events

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

- Loss of engine power, cruise - normal
  - reason for occurrence undetermined (cause)
- Loss of control - in flight, maneuvering - turn to landing area (emergency)
  - airspeed(vs) - not maintained, unqualified person (cause)
  - stall/mush - inadvertent, unqualified person (cause)
- In flight collision with terrain/water, descent - uncontrolled
  - terrain condition - water

## Analysis

WHILE ATTEMPTING TO PERFORM A PRECAUTIONARY LANDING ON A BEACH FOLLOWING A PARTIAL LOSS OF ENG POWER DURING CRUISE FLT, THE NON FAA CERTIFICATED PLT INADVERTENTLY STALLED THE AIRPLANE WHICH DESCENDED UNCONTROLLED & COLLIDED WITH THE WATER IN A NOSE & RT WING LOW ATTITUDE.  HE FURTHER STATED THAT HE BELIEVES THAT THE LOSS OF POWER WAS DUE TO OVERHEATING OF THE ENG.  IT WAS NOT EXAMINED THEREFORE NO DETERMINATION COULD BE MADE AS TO THE REASON FOR THE PARTIAL LOSS OF POWER.  THE AIRPLANE WAS NOT REGISTERED WITH THE FAA BUT WAS REQUIRED TO BE.
