What is used to inflate an oleo type landing gear shock strut? |
High pressure source of dry air or nitrogen |
|
|
When should landing gear retraction checks be accomplished? |
During annual and other type inspections, after replacing landing gear components, and after and hard landing. |
|
|
What are two sources of power used to extend and retract landing gear? |
hydraulic and electrical |
|
|
Where would you look to find proper tire inflation information? |
Operation Manual and the Aircraft Maintenance Manual. |
|
|
What is the purpose of a hydraulic shimmy damper? |
It is a unit designed to prevent nose wheel vibration or shimmy during taxiing, landing, or takeoff. |
|
|
What type care should be given to landing gear shock struts? |
They should be inspected regularly for leakage of fluid and for proper extension. The exposed portion of the strut piston should be wiped clean daily and inspected for scoring or corrosion. |
|
|
What is the effect of under inflated tires? |
Under inflated tires are more likely to creep or slip on the wheel when landing or when brakes are applied. Under inflation also causes rapid uneven wear at or near the edges of the tread. |
|
|
What is the purpose of the rubber o-ring mounted on the mating surface of the outer wheel half of a split type wheel? |
To prevent air leakage from the tubeless tire used with this wheel. |
|
|
What are three types of aircraft brake systems? |
Independent, the power boosted, and the power control type. |
|
|
What is the purpose of a shuttle valve in a power control system? |
Isolating the emergency brake system from the normal brake system. |
|
|
What component in the landing gear system keeps the landing gear in alignment? |
The landing gear torque links |
|
|
What is used to prevent a nose gear from being retracted with the wheel out of the center position? |
Internal centering cam or an external track, that straighten the nose wheel before it enters the wheel well. |
|
|
What is the purpose of the fusible plug in some aircraft tire? |
To melt at a specific elevated temperature and relieve air pressure to prevent the tire from blowing out or breaking the wheel. |
|
|
What is the purpose of the anti-skid system? |
To bring the airplane to a stop without skidding by providing the most effective braking power under all types of runway conditions. |
|
|
What are two methods of bleeding brakes? |
Gravity method and the pressure method. |
|
|
When inspecting brakes, what do you look for? |
1. Check for leaks while the system is pressurized 2. Check for flex hoses swelling, cracking, of soft spots. 3. Check brake pedals for spongy actuation 4. Check brake pedals for excessive travel. |
|
|
What do you do before disassembling an oleo strut? |
Discharge the Pressure. |
