Narrative:
THE PILOT STATED THAT SHORTLY AFTER TAKEOFF, THE EGT GAGE FOR ONE OF THE TWO CYLINDERS WAS INDICATING HIGHER THAN NORMAL. HE INITIATED A TURN TO RETURN FOR LANDING BUT THE ENGINE FAILED DUE TO FUEL STARVATION. HE THEN INADVERTENTLY STALLED AND SPUN THE AIRPLANE WHICH CRASHED INTO A POND ON THE AIRPORT. THE AIRPLANE WAS RECOVERED AND EXAMINATION REVEALED THAT THE CAUSE OF THE FUEL STARVATION WAS DUE TO THE IMPROPER PLACEMENT OF A 'Y' FITTING WHICH CONNECTS THE FORE AND AFT FUEL LINES FROM EACH FUEL TANK. THE PILOT HAD PLACED THE 'Y' FITTING IN THE CENTER OF THE FUEL TANK BETWEEN THE FORE AND AFT FUEL WITHDRAWALS AT THE BOTTOM EDGE OF THE TANK. THE CORRECT PLACEMENT OF THE FITTING IS ABOUT 12 INCHES BELOW THE FUEL TANK.

Probable Cause: FAILURE OF THE PILOT TO MAINTAIN ADEQUATE AIRSPEED AND INADVERTENT STALL/SPIN. CONTRIBUTING TO THE ACCIDENT WAS TOTAL LOSS OF ENGINE POWER DUE TO FUEL STARVATION. THIS WAS DUE TO IMPROPER PLACEMENT OF A COMPONENT OF THE FUEL SYSTEM BY THE BUILDER/PILOT.
