Landing gear

Deteriorated flexible hoses

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

The pedal to slowly creep down while pedal pressure is applied

Internal leakage in a brake master cylinder unit can cause

Expander-tube type

Many brake types can be adapted to operate mechanically or hydraulically. Which type is not adaptable to mechanical operation

Extend the landing gear if the normal operating mechanism fails

On all aircraft equipped with retractable landing gear, some means must be provided to

Prevent heavy spot and reduce vibration

The primary purpose for balancing aircraft wheel assemblies is to

Compensate for thermal expansion

The purpose of a relief valve in a brake system is to

Ensure operation of the landing gear and gear doors in the proper order

The purpose of a sequence valve in a hydraulic retractable landing gear system is to

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

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

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

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

The restriction will cause slow release of the brakes

What is one effect a restricted compensator port of a master cylinder will have on a brake system

Straighten the nose wheel

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

Permits the fluid to flow toward or away from the reservoir as temperature changes

What is the purpose of a compensating port or valve in a brake master cylinder of an independent brake system?

Maintain correct wheel alignment

What is the purpose of the torque links attached to the cylinder and piston of a landing gear oleo strut

The brakes would drag

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

The fluid being forced through a metered opening

When an air/oil type of landing gear shock strut is used, the initial shock of landing is cushioned by

high landing speeds

power boost brake systems are used on aircraft that have

An internal leak in the master cylinder

Aside external leak in the line, what will cause parking brakes to continually bleed off pressure?

Strut should be removed, disassembled, and inspected

If a shock strut bottoms after it has been properly serviced, the

Low fluid

If an aircraft shock strut (air/oil type) bottoms upon initial landing contract, but functions correctly during taxi, the most probable cause is

Worn brake linings

If an airplane equipped with master cylinders and single-disk brakes has excessive brake pedal travel, but the brakes are hard and effective, the probable cause is
