## Discrepancy

A SHORT IN THE LANDING GEAR HYD SAFETY VALVE CAUSED THE TRIPPING OR CIRCUIT BREAKERS LGCIU SYS 1 AND LGCIU SYS 1 GRD SUP.  THE FAILURE CONDITION OF THE LANDING GEAR SAFETY VALVE CAUSING THE TRIPPING OF THE CIRCUIT BREAKERS AUTOMATICALLY FORCED THE ACFT INTO THE AIR MODE.  AIR MODE ON THIS ACFT MAY REMOVE HYD POWER TO BRAKES, NOSE WHEEL STEERING AND THRUST REVERSERS, A POTENTIALLY HAZARDOUS CONDITION.
