Aircraft Landing Gears

LANDING GEAR

a. The landing gear on aircraft may be fixed or retractable. A fixed gear may be wheels, floats, or skis; and for amphibians a combination of floats and wheels.
b. Retractable gear on aircraft is usually operated with hydraulic or electric power, although some models of light general aviation aircraft have manual retract systems operated by a lever in the cockpit.
      
       (1) In addition to the normal operating
             system, emergency systems are usually provided
             to ensure that the landing gear can be
             lowered in case of main-system failure.
       (2) Emergency systems consist of
             backup hydraulic systems, or stored nitrogen
             gas bottles that can be directed into actuating
             cylinders, mechanical systems that can be operated
             manually, or free-fall gravity systems.

GENERAL INSPECTION. 
A thorough inspection of the landing gear involves the entire structure of the gear, including attachments, struts, wheels, brakes, actuating mechanisms for retractable gears, gear hydraulic system and valves, gear doors, and all associated parts. The manufacturer’s inspection procedures should be followed where applicable.
