## Discrepancy

(CAN) LANDING GEAR FAILED TO OPERATE DUE TO LOSS OF ALL HYDRAULIC FLUID BECAUSE OF A FAILED O-RING IN THE LEFT MAIN GEAR ACTUATOR. THIS RESULTED IN A GEAR UP LANDING WITH NOSE GEAR DOWN AND MAIN GEAR UP. MAJOR KEEL DAMAGE TO BOTTOM OF BOTH FLOATS. SUBMITTER SUGGESTS THAT WIPLINE SL #28 BE MANDATORY.
