Amateur-built SONERAI II STRETCH N1927B accident near De Leon Springs, Florida

Probable cause

A total loss of engine power for reasons that could not be determined because postaccident examination of the airframe and engine revealed no evidence of preexisting mechanical anomalies or failures that would have precluded normal operation.

NTSB analysis

The pilot reported that, about 40 minutes into the local flight, the engine lost total power. He was unable to restart the engine, so he conducted a forced landing. The airplane collided with trees and terrain and came to rest inverted. The pilot reported that he began the flight with 9 gallons of fuel on board and used about 3 gallons during the flight. Although only evidence of residual fuel was found in the fuel system, the impact breached the fuel system, and rain was present at the wreckage site after the accident. A postaccident examination of the airframe and engine revealed no evidence of preexisting mechanical anomalies or failures that would have precluded normal operation. The reason for the engine power loss could not be determined.
