Probable cause
A partial loss of engine power due to the improper assembly of the mechanical fuel pump.
NTSB analysis
The airline transport pilot was conducting the first flight test of the experimental, amateur-built airplane when, shortly after takeoff, the engine experienced a partial loss of power. The airplane was unable to maintain altitude, and the pilot conducted a forced landing to a tree nursery about 1 mile from the airport. Postaccident examination of the engine revealed that the mechanical fuel pump housing screws were slightly loose, and the fuel screen was not properly seated. Although an engine run and several high-speed taxi runs were conducted before the flight without any observed anomalies, it is likely that the pump housing screws further loosened during these tests and subsequently allowed air to enter the fuel system during flight, disrupting the fuel flow to the engine.
