FURTHER INVESTIGATION REVEALED TWO OF THE THREE BOLTS SECURING THE ACTUATOR WERE SHEARED OFF INSIDE THE MAIN GEAR SUPPORT, AND BEING HELD FLUSH IN PLACE BY THE SAFETY WIRE. THE LT ACTUATOR ALSO HAD ONE BOLT SHEARED POSSIBLY CONTRIBUTING FACTOR IS THE GREAT AMOUNT OF TORQUE PLACED ON THE ACTUATORS WHEN THE GEAR REACHES BOTH THE UP AND DOWN STOPS. SUBMITTER SUGGESTS REMOVING AND INSPECTING THESE BOLTS EVERY 2 YEARS OR 250 HOURS.
