What was found
DURING A 3 YEAR INSPECTION OF THE EMERGENCY FLOAT GEAR SYSTEM THE INFLATION ACTUATION HANDLE BROKE, THE FLOATS DID NOT ACTUATE. TO CONTINUE THE INSPECTION THE ACTUATION CABLE WAS PULLED DIRECTLY, IT REQUIRED A LOT OF PULL TO INITIATE FLOAT INFLATION. ONCE INITIATED FLOATS INFLATED NORMALLY. SUSPECT THAT THE FLOAT RESERVOIR VALVE WHICH WAS DUE FOR OVERHAUL AT THE END OF THE MONTH WAS STUCK AND SURPASSED THE ACTUATION HANDLE'S ABILITY TO MOVE IT CAUSING IT TO SHEAR.
