(8305) - Exposure to and/or storage near which of the following is considered harmful to aircraft tires? 1. Low humidity. 2. Fuel. 3. Oil. 4. Ozone. 5. Helium. 6. Electrical equipment. 7. Hydraulic fluid. 8. Solvents.

A- 2, 3, 4, 5, 6, 7, 8. B- 1, 2, 3, 5, 7, 8. C- 2, 3, 4, 6, 7, 8.

(8310) - Aside from an external leak in the line, what will cause parking brakes to continually bleed off pressure?

A- An internal leak in the master cylinder. B- Insufficient hydraulic fluid in the reservoir. C- Glazed brake linings.

(8306) - What would be the effect if the piston return spring broke in a brake master cylinder?

A- The brakes would become spongy. B- The brake travel would become excessive. C- The brakes would drag.

(8311) - 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?

A- To allow the tube to position itself correctly inside the tire. B- To eliminate all the air between the tube and the inside of the tire. C- To test the entire assembly for leaks.

(8308) - To prevent a very rapid extension of an oleo shock strut after initial compression resulting from landing impact,

A- various types of valves or orifices are used which restrict the reverse fluid flow. B- the metering pin gradually reduces the size of the orifice as the shock strut extends. C- the air is forced through a restricted orifice in the reverse direction.

(8312) - The metering pins in oleo shock struts serve to

A- lock the struts in the DOWN position. B- retard the flow of oil as the struts are compressed. C- meter the proper amount of air in the struts.

(8309) - 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- the hydraulic master cylinder piston is sticking. B- air in the brake hydraulic system. C- the hydraulic master cylinder piston return spring is weak.

(8307) - 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.
