- Main gear collapsed, landing - roll
  - terrain condition - high vegetation (contributing factor)
  - ground loop/swerve - uncontrolled
  - landing gear,main gear - overload
  - landing gear,tailwheel - separation

## Analysis

HYDRAULIC MOTOR ACTIVATED LIGHT REMAINED ON AFTER LANDING GEAR RETRACTION. THE PILOT BELIEVING THIS TO INDICATE A LANDING GEAR MALFUNCTION SLOWED THE ACFT AND EXTENDED THE GEAR. A GEAR DOWN INDICATOR ILLUMINATED. HOWEVER, THE HYDRAULIC MOTOR ACTIVATED LIGHT REMAINED ILLUMINATED. WHILE CONTINUING TO TROUBLESHOOT WHAT HE BELIEVED TO BE A LANDING GEAR PROBLEM, THE ENGINE OVERHEATED AND LOST POWER. WHILE ATTEMPTING TO MAKE A FORCED LANDING ON A ROAD THE HYDRAULICALLY OPERATED FLAPS WOULD NOT EXTEND. THE LANDING GEAR EXTENDED NORMALLY. DURING ROLLOUT THE AIRCRAFT STRUCK BRUSH AND GROUNDLOOPED. THE LANDING GEAR COLLAPSED AND THE TAIL WHEEL SEPARATED FROM THE AIRCRAFT. THE CAUSE OF THE HYDRAULIC MOTOR ACTIVATED LIGHT ILLUMINATION WAS NOT DETERMINED. THE PILOT DID NOT PULL THE HYDRAULIC MOTOR CIRCUIT BREAKER.
