F50/900/2000 MLG Outboard Door Hinge

January 2013

steel fastener corrosion

During the course of the last six months technicians at Duncan Aviation have found several MLG OB door hinges seized. With the aircraft jacked and the OB door to gear tie rod removed, retract the gear. Make sure that excessive force is not needed in the door movement and that it swings free throughout its full travel. Also during the next scheduled 1A inspection per task code 32-10-00-640-801, it is recommended that you liberally grease with lube oil in the hinge area.
