1
Q
  1. What are two sources of power used to extend & retract landing gear?
A

Electrical & Hydraulic

2
Q
  1. When should landing gear retraction checks be accomplished?
A

Annual
replacing landing gear component
after hard landing

3
Q
  1. What is used to inflate an oleo type landing gear shock strut?
A

High pressure dry air or Nitrogen

4
Q
  1. Where would you look to find proper tire inflation information?
A

Operation or Maintenance Manuals

5
Q
  1. What is the purpose off a hydraulic shimmy damper?
A

Prevents nose wheel vibrations during taxi, landing, or takeoff

6
Q
  1. What type of care should be given to landing gear shock struts?
A

Inspected regularly for leaks & proper extension
Wipe piston strut clean daily and inspect for scoring or corrosion

7
Q
  1. What is the effect of under inflated tires?
A

Rapid uneven wear near edges, tire can slip or creep on landing

8
Q
  1. What is the purpose of the rubber O-ring mounted on the mating surface of the outer wheel half of a split type wheel?
A

Prevents air leaks from tubeless tires

9
Q
  1. What are three types of aircraft brakes systems?
A

Independent
Power boosted
Power control

10
Q
  1. What is the purpose of a shuttle valve in a power control system?
A

Isolates the emergency brake system from normal brakes

11
Q
  1. What is the purpose of the main landing gear torque link?
A

Keeps landing gear alignment

12
Q
  1. What is used to prevent a nose gear from being retracted with the wheel out of the center position?
A

Centering device like internal centering cam or an external track

13
Q
  1. What is used in a split wheel assembly to keep the air rom leaking out between the wheel halves?
A

O-ring

14
Q
  1. What is the purpose of the fusible plug in some aircraft wheels?
A

Melts at specific temperatures to relief air pressure

15
Q
  1. How should aircraft tires be stored?
A

In a cool, dry place, away from chemicals, oil, or sunlight

16
Q
  1. What is the most important maintenance consideration for aircraft tires?
A

Properly inflated

17
Q
  1. What safety procedure should be followed when inflating tires in general?
A

Inflate inside a cage

18
Q
  1. What is the purpose of the anti-skid system?
A

Stop aircraft without skidding, most effective braking in all runway conditions

19
Q
  1. What task should be accomplished if the aircraft brakes are spongy?
A

Bleed brakes

20
Q
  1. What are two methods of bleeding brakes?
A

Gravity & pressure

21
Q
  1. When inspecting brakes, what do you look for?
A

Leaks when pressurized
Flex hoses for swelling, cracking, or soft spots
Brake pedals for spongy actuation
Brake pedals for excessive travel

22
Q
  1. What must you do before disassembling an ole strut?
A

Discharge pressure

23
Q
  1. Where can you find instructions for jacking one wheel of an aircraft to change a tire?
A

Aircraft maintenance manual
