What was found
IN THE MIDST OF A TOUCH-AND-GO, THE OIL PRESSURE INDICATION ON THE GARMIN G-1000 RED X'D THE OIL PRESSURE INDICATION AT AND ABOVE 1800 ENGINE RPM. THE TOUCH-AND-GO WAS CHANGED TO FULL PROPER LANDING. ONCE WE REMOVED THE OIL PRESSURE TRANSDUCER P/N 265-037-1, S/N A2219 AND REPLACED IT, THE PROBLEM WENT AWAY. THIS OIL PRESSURE TRANSDUCER ONLY HAD 933.3 HOURS ON IT AND WAS ONLY 2 YEARS OLD.
