Probable cause & findings
THE PILOT NOT FOLLOWING THE SPECIFICATION FOR INSTALLATION OF THE FUEL TANK VENT.
Factual narrative
THE OWNER BUILDER OF AN EXPERIMENTAL AIRPLANE EXPERIENCED PARTIAL POWER LOSS DURING CLIMB FROM TAKEOFF ON A TEST FLIGHT AFTER COMPLETION OF CONSTRUCTION. THE AIRPLANE LANDED OFF AIRPORT. EXAMINATION OF THE ENGINE REVEALED NO DISCREPANCY. THE SOLE DISCREPANCY FOUND ON THE FUEL SYSTEM WAS A FUEL TANK VENT CUT SQUARELY ACROSS INSTEAD OF THE KIT MANUFACTURER'S SPECIFIED FORWARD FACING ANGLE CUT.
