| Confidence Rating: |  Accident investigation report completed and information captured |
The pilot reported that during cruise flight, at 1,000-feet agl, his experimental, pusher engine, hull configured amphibian sustained a propeller blade(s) separation and when he reduced power to alleviate the extreme vibration, the engine quit. The pilot's only option was to attempt an emergency landing to a clear spot in an abandoned orange grove. The aircraft collided with sand furrows and high vegetation sustaining heavy damage to the airframe. Examination of the wreckage revealed that 2 of the 3 composite propeller blades were missing as well as the engine's left/front exhaust pipe. All that remained of the missing exhaust pipe was its attaching hardware to its exhaust port and a short stub revealing a 360-degree circumferential crack.
Probable Cause: The in-flight separation of one of the propeller blade's and one of the engine's exhaust pipes causing the engine to vibrate until it stopped running. A related factor was the unsuitable terrain for the forced landing.
