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
