1902. LANDING GEAR SYSTEM

The landing gear system (Figure 19-1) is an electrically operated, fully retractable, tricycle type

landing gear. The main gear retracts inboard into the wings and the nose gear retracts aft into the

fuselage. The landing gear system is actuated by a single reversible DC motor and gearbox

mechanism which is located under the front cockpit. Due to the high speed (10,500 RPM) of the

motor, the gear will extend and retract in four seconds.

System Operation

When the landing gear handle is moved to the UP or DOWN position, motion of the gear is

achieved by action of the DC motor and gearbox mechanism through a push-pull rod to each

main gear V-brace and the nose gear V-brace. The V-braces further connect to a side brace on

the main gear and a drag brace on the nose gear which then further connects to each landing gear
