M7 Part 1

1. To locate fault in the AC wiring, one should refer to the:

Wiring diagram manual

Maintenance manual

Component location diagram manual

2. A piece of metal structure has surface pitting and etching covered with white powdery deposit, based on this evidence you would consider that it is

Aluminum alloy or magnesium

Copper or copper alloy

Iron or steel

3. When taxiing an aircraft in a ramp a flashing green light is signaled from a tower, would indicate that the aircraft

Must return to the starting point

May commence taxiing

Must exercise extreme caution

4. When a replenishment cart contains both oxygen and nitrogen cylinders, nitrogen would be

Significantly larger than oxygen bottles

Mounted in the opposite direction to the oxygen bottles and have different hose connection

Greater in number and colored black and white.

5. After finding severe skin damage resulting from a lightning strike, all control surfaces must be inspected to check for damage because

Unsatisfactory bonding may have allowed static discharge across hinge bearings, burning, breakup or seizure

The hinge bearing may have become magnetized

The mass balance of the control surface may have change

6. A set of wheel bearing requires grease remove and cleaning prior to inspection as acceptable cleaning method would be

To use a commercial chemical based cleaner to soak the bearing, then spin the bearing dry using shop air

7. It should be possible to install the control rigging pin easily if the:

Final alignment of the control system is correct.

Cable tension is low

Cable tension is excessive

8. It is highly dangerous to operate the halves of pressurized ______cylinders with greasy hand

Oxygen

Nitrogen

Acetylene

9. Defueling of AC must be carried out

Outside a hanger where there are no fire hazards

In a hanger where there is no wind or fire hazards

Into clean drums but no straight into a fuel tank.

10. To measure the electrical resistance of a fire bottle squib:

A megger is used

Any ohmmeter is used

A safety ohmmeter is used

11. A control chain should be rejected if:

If has twists or kinks of more than 2 degree

It has any evidence of twists or kinks

It has twists or kinks of more than 5 degress

12. The bearing of a pulley in a cable control system

Is normally prepacked with grease

Should be lubricated with a spray type lubricant only

Must be lubricated with grease after every flight

13. A wheel bearing cup has water marking. The marking area is not rusted. The bearing should

Reinstalled and re-inspected for an deterioration at the next schedule inspection

Reinstalled as water marking is common and not cause for bearing failure

Reject as water marks area are an indication of inter-granular corrosion

14. The smallest graduated grading on a metric vernier caliper is

0.02mm

0.5mm

0.001mm

15. The thread on the spindle of an English micrometer has a pitch of

100 threads per inch, and one complete turn off the thimble will move 0.025 inch

40 threads per inch, and one complete turn off the thimble will move 0.025 inch

50 threads per inch, and one complete turn off the thimble will move 0.025 inch

16. If a 25 inch torque wrench fitting with a 5 inch extension shows a dial reading of 100 inch pounds, the actual torque loading on a bolt would be

80 inch pounds

130 pounds

120 pounds

17. If mercury is spilled in the cargo hold of an aircraft it will have the most damaging effect on structure containing

Magnesium

Aluminum alloy

Titanium

18. When refueling from a hydrant cart containing Jet Aluminum fuel the decal marking should be coloured

Blue with white lettering

Black with white lettering

Red with white lettering

19. Loads on the surface of the wing during normal flight will result in

Compression of the upper surface and both compression and tension on the lower surface

Tension of the upper surface and compression of the lower surface

Compression of the upper surface and tension of the lower surface

20. When inspecting the gear teeth on the helical input pinion gear, the tooth contact pattern is found to be too high. This condition will

Result in insufficient fear backlash and inadequate gear tooth gear tooth lubrication.

Not be adjustable and required gear replacement

Allow excessive gear backlash and overloading of the gear teeth
