Landing gear Maintenance Repair, Overhaul, Re-Certification.

Landing gear CLEANING AND LUBRICATING. It is recommended that only easily removable neutral solutions be used when cleaning landing gear components. Any advantage, such as speed or effectiveness, gained by using cleaners containing corrosive materials, can be quickly counteracted if these materials become trapped in 'Nose-fitting surfaces and crevices. Wear points, such as landing gear up-and-down latches, jack-screws, door  hinges, pulleys, cables, bell-cranks, and all pressure-type grease fittings should be relubricated after every cleaning operation. To obtain proper lubrication of the main support bushings, it may be necessary to jack the aircraft.

Anytime the aircraft is on jacks, check the landing gear main support bushings for wear. Consult the aircraft manufacturer's overhaul manual for specific wear tolerances.

During winter operation, excess grease may congeal and cause increased loads on gear retraction system electric motors and hydraulic pumps. This condition can lead to

component malfunctions; therefore, it is recommended that cleanliness be stressed

during and after lubrication.

EMERGENCY SYSTEMS. Exercise emergency landing gear systems periodically to ensure proper operation and to prevent inactivity, dirt, and corrosion from rendering the system inoperative when needed. Most emergency systems employ either mechanical, pressure-bottle or free-fall extension capabilities. Check for proper safetying of  triggering mechanisms, and for the presence of required placards and necessary accessories such as cranks, levers, handles, etc.

Landing gear SPECIAL INSPECTIONS. Any time an aircraft has experienced a hard or overweight landing, it is recommended that a special structural inspection, which

includes the landing gear, be performed. Typical areas which require special attention

are landing gear support trusses for cracked welds, sheared bolts and rivets, and

buckled structures; wheels and tyres for cracks and cuts; and upper and lower wing

surfaces for wrinkles, deformation, and loose or sheared rivets. If any damage is

found, a detailed inspection is recommended.

Landing gear RETRACTION TESTS. Periodically, perform a complete operational check of the landing gear retraction system. Inspect the normal extension and retraction system, the emergency extension system, and the indicating and emergency warning system.

Determine that the actuating cylinders, linkage, slide tubes, sprockets, chain or drive

gears, gear doors, and the up-and-down locks are in good condition and properly

adjusted and lubricated. In addition an electrical continuity check of micro-switches

and associated wiring is recommended. Only qualified personnel should attempt

adjustments to the gear position and warning system microswitches and then only by

closely following the manufacturer's recommendations.
