What was found
(CAN) ON THE TAKEOFF ROLL, THE R/H ENGINE FAILED TO DEVELOP FULL POWER. THE TAKEOFF WAS ABORTED AND A GROUND RUN PERFORMED. A SECOND TAKEOFF WAS ATTEMPTED, THIS TIME DEVELOPING FULL POWER, BUT ONCE AGAIN WHEN AIRBORNE BEGAN TO LOSE POWER. THE AIRCRAFT LANDED WITHOUT INCIDENT. A SUBSEQUENT INSPECTION AND GROUND RUN COULD FIND NO FAULT, BUT WATER AND ICE CRYSTALS WERE FOUND IN THE FUEL SUMPS. THE SUMPS WERE DRAINERD AND A TEST FLIGHT FOUND THE AIRCRAFT FUNCTIONING NORMALLY.
