What was found
(CAN) LANDING GEAR HYDRAULIC PRESSURE GAUGE READS INCORRECTLY. THE GAUGE IS RATED FOR 2000 PSI, AND THE SYSTEM OPERATES AT 2000 PSI. SUBMITTER STATES THAT THE RELIEF VALVE FUNCTIONS AT 2200 PSI AND THIS PUTS UNDO STRAIN ON THE GAUGE DURING HOT WEATHER RELATED THERMAL RELIEF, HENCE THE GAUGE BEGINS TO READ INCORRECTLY. SUBMITTER SUGGESTS REPLACING THE GAUGE WITH A HIGHER RATED ONE.
