b) retarded and gear is down and locked

c) retarded and gear is not down and locked - ANS_c) retarded and gear is not down and locked



Why do tire and wheel manufacturers often recommend that the tires on split rim wheels be deflated
before removing the wheel from the axle?

a) To remove the static load imposed upon the wheel bearings by the inflated tire

b) As a safety precaution in case the bolts that hold the wheel halves together have been damaged or
weakened

c) To relieve the strain on the wheel retaining nut and axle threads - ANS_b) As a safety precaution in
case the bolts that hold the wheel halves together have been damaged or weakened



Chines are used on some aircraft nose wheel tires to help

a) reduce the possibility of hydroplaning

b) deflect water away from the fuselage

c) nose gear extension at higher air speeds - ANS_b) deflect water away from the fuselage



When a properly operating fusible plug has allowed a tire to deflate, the tire should be

a) removed from the wheel and inspected for carcass and tread damage

b) replaced

c) externally inspected for damage - ANS_b) replaced



Instructions concerning the type of fluid and amount of air pressure to be put in a shock strut are found

a) on the airplane data plate

b) in the aircraft manufacturer's service manual

c) in the operations limitations - ANS_b) in the aircraft manufacturer's service manual

,Overinflated aircraft tires may cause damage to the

a) wheel flange

b) wheel hub

c) brake linings - ANS_a) wheel flange



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

a) withdrawing air only from the system

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

c) replacing small amounts of fluid in reservoir - ANS_b) withdrawing fluid from the system for the
purpose of removing air that has entered the system



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

a) air in the brake hydraulic system

b) the hydraulic master cylinder piston return spring is weak

c) the hydraulic master cylinder piston is sticking - ANS_a) air in the brake hydraulic system



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

a) retract and extend the landing gear if the normal operating mechanism fails

b) extend the landing gear if the normal operating mechanism fails

c) prevent the throttle from being reduced below a safe power setting while the landing gear is
retracted - ANS_b) extend the landing gear if the normal operating mechanism fails



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 consists of

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

b) shimming the axle in the oleo trunion

c) placing shims or spacers behind the bearing of the out of tolerance wheel or wheels - ANS_a)
inserting, removing, or changing the location of washers or spacers at the center pivotal point of the
scissor torque links



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

a) glazed brake linings

b) an internal leak in the master cylinder

c) insufficient hydraulic fluid in the reservoir - ANS_b) an internal leak in the master cylinder



How can it be determined that all air has been purged from a master cylinder brake system?

a) by operating a hydraulic unit and watching the system pressure gauge for smooth, full-scale
deflection

b) By noting the amount of fluid return to the master cylinder upon brake release

c) By noting whether the brake is firm or spongy - ANS_c) By noting whether the brake is firm or spongy



Aircraft tire pressure should be checked

a) using only a push stick type gauge having 1 pound increments

b) as soon as possible after each flight

c) at least once a week or more often - ANS_c) at least once a week or more often



An O-ring intended for use in a hydraulic system using MIL-H-5606 (mineral base) fluid will be marked
with

a) a white and yellow stripe

b) one or more white dots

, c) a blue stripe or dot - ANS_c) a blue stripe or dot



An automatic damping action occurs at the steering damper if for any reason the flow of high pressure
fluid is removed from the

a) inlet of the steering damper

b) replenishing check valve

c) outlet of the steering damper - ANS_a) inlet of the steering damper



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

a) hold the strut in place

b) maintain correct wheel alignment

c) limit compression stroke - ANS_b) maintain correct wheel alignment



A flexible hydraulic hose identified as MIL-H-8788 will have a stripe running the length of the hose. This
stripe

a) identifies that the hose is for high pressure fluids, with a 60 degree flexing range

b) indentifies that the hose is constructed of teflon and is suitable for a wide temperature range

c) is used to ensure that the hose is installed without excessive twisitng - ANS_c) is used to ensure that
the hose is installed without excessive twisitng



Debooster valves are used in brake systems primarily to

a) reduce brake pressure and maintain static pressure

b) ensure rapid application and release of the brakes

c) reduce the pressure and release the brakes rapidly - ANS_c) reduce the pressure and release the
brakes rapidly



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