## Probable cause

THE PILOT'S FAILURE TO MAINTAIN AN AIRSPEED ABOVE STALLING DURING MANEUVERING FLIGHT. A FACTOR RELATING TO THE ACCIDENT WAS OPERATING AT AN ALTITUDE INADEQUATE IN WHICH TO EFFECT RECOVERY.

## Analysis

THE PILOT IN COMMAND WAS ATTEMPTING TO SURVEY AN INTENDED LANDING AREA BY PERFORMING A LOW APPROACH.  HE MADE HIS TURN FROM THE WATER TOWARD THE BEACH AT 200 ABOVE GROUND LEVEL. DURING THE TURN THE AIRSPEED BEGAN TO DROP AND THE AIRPLANE BEGAN TO DESCEND AND POWER WAS APPLIED.  THE PILOT ROLLED THE AIRPLANE WINGS LEVEL AND THE AIRPLANE CONTINUED TO DESCEND UNTIL IT STRUCK THE GROUND.  THE WIND WAS LIGHT AND VARIABLE.

- Loss of control - in flight, maneuvering
  - airspeed(vs) - not maintained, pilot in command (cause)
- In flight collision with terrain/water, descent - uncontrolled
  - altitude - inadequate, pilot in command (contributing factor)
