Aircraft Landing Gear Systems

When servicing an air/oil shock strut with MIl 5606 the strut should be

Collapsed and fluid added at the filler opening

If it is determined that spongy brake action is not caused by air in the brake system, what is the next most likely cause?

Deteriorated flexible hoses

What should be checked when a shock strut bottoms during landing?

Fluid Level

Which repair would require a landing gear retraction test?

Gear donwlock microswitch

The repair for an out of tolerance toe in condition of main landing gear wheels determined not to be the result of bent or twisted components consist of

Inserting, removing , or changing the location of washers or spacers at the center pivotal point of the scissor torque links

Debooster valves are used in brake systems primarily to

Reduce the pressure and release the brakes rapidly

What is the function of a cam incorporated in a nose gear shock strut?

Straightens the nosewheel

What would be the effect in the piston return spring broke in a brake master cylinder?

The brake would drag

Aircraft brakes requiring a large volume of fluid to operate the brakes generally

Use power brakes control valves

To prevent a very rapid extension of an oleo shock strut after initial compression resulting from landing impact.

Various types of valves or orifices are used which restrict the reverse fluid flow

A pilot reports the right brake on a n aircraft is spongy when the brake pedal is depressed in a normal manner. The probable cause is

air in the brake hydraulic system

Nose gear centering cams are used in many retractable landing gear systems. The primary purpose of the centering device is to

center the nose wheel before it enters the wheel well

A sleeve , spacer , or bumper rins is incorporated in a landing gear oleo shock strut to

limit the extension stroke

A landing gear position and warning system will provide a warning in the cockpit when the throttle is

retarded and gear is not down and locked

A brake debooster valve is installed in systems where the high pressure of the hydraulic system os used to operate brakes

that are designed to work with lower pressure

The pressure source for power is

the main hydraulic system

In the brake service work, the term, bleeding brakes is the process of

withdrawing fluid from the system for the purpose of removing air that has entered the sytem
