What was found
ON A TOUR FLIGHT, THE PILOT LOST GENERATOR OUTPUT. TURNED AROUND AND MADE A SAFE LANDING AT THE AIRPORT. THE GENERATOR WIRES WERE RUBBING ON THE CARBON FIBER ENGINE COWLING AND SHORTED TO AIRFRAME GROUND. THIS IS A PROBLEM WITH THE STC SH3324NM CONVERSION KIT FOR ENGINE. THERE IS NO MEANS TO CLAMP OR SECURE THE WIRE HARNESS AWAY FROM THE COWLING. THE STC HOLDER SHOULD MODIFY THE STC WITH A METHOD OF CLAMPING THE WIRE HARNESS AWAY FROM THE COWLING. (K)
