Confidence Rating: Accident investigation report completed and information captured
The private pilot said he performed a preflight inspection of the airplane and let the engine warm up to normal operating temperature before he taxied to the runway and performed a normal run-up of the engine. During takeoff, the engine lost power. The pilot attempted to return and land on the reciprocal runway but landed about 300 ft southeast of the runway on grass. The landing gear collapsed during the landing, which resulted in substantial damage to the airframe.
Engine performance data downloaded from the airplane’s onboard electronic display revealed that the fuel flow to the engine was interrupted shortly before the end of the flight. A postaccident examination of the engine revealed no mechanical anomalies that would have precluded normal operation, and during a test run of the engine on the airframe, it ran continuously for several minutes without hesitation. Examination of the fuel system revealed that no fuel return line (or fuel restriction line) had been installed, which was not in accordance with the engine manufacturer's installation instructions. The engine installation manual stated that the purpose of the fuel return line was to prevent the formation of fuel vapor lock. It is likely that the absence of the fuel return line resulted in the engine losing power due to fuel vapor lock.

Probable Cause: A total loss of engine power due to fuel vapor lock. Contributing to the accident was the absence of a fuel return line.
