AMT 135 8083-31A CH 13 Landing Gear

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

• A blue stripe or dot

• One or more white dots

• A white and yellow stripe

Aircraft tire pressure should be checked

• Using only a push on stick-type gauge having 1-pound increments

• At least once a week or more often

• As soon as possible after each flight

What condition would most likely cause excessive fluctuation of the pressure gauge when the hydraulic pump is operating?

• Accumulator air pressure low

• Inadequate supply of fluid

• System relief valve sticking closed

A special bolt in a landing gear attachment requires a torque value of 440 inch-pounds. How many foot-pounds are required?

• 36.8

• 38

• 36.6

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

• Limit compression stroke

• Hold the strut in place

• Maintain correct wheel alignment

Why do most aircraft tire manufacturers recommend that the tubes in newly installed tires be first inflated, fully deflated, and then reinflated to the correct pressure?

• To allow the tube to position itself correctly inside the tire

• To eliminate all the air between the tube and the inside of the tire

• To test the entire assembly for leaks

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

• Advanced and gear is down and locked

• Retarded and gear is down and locked

A brake debooster valve is installed in systems where the high pressure of the hydraulic system (3000 psi) is used to operate brakes

• That are designed to work with lower pressure

• That are used in conjunction with an antiskid system

• That are used on aircraft having high landing speeds

Power boost brake systems are used on aircraft that have

• High landing speeds

• Low normal hydraulic system pressure

• More than one brake assembly per axle

Chines are used on some aircraft nose wheel tires to help

• Nose gear extension at higher air speeds

• Reduce the possibility of hydroplaning

• Deflect water away from the fuselage
