AME - Aircraft Maintenance Engineer Maintenance Practices and Materials Questions and Answers

Question 1

An AME is performing a visual inspection on a section of aluminum alloy aircraft skin and observes small, white or gray powdery deposits. This is indicative of which type of corrosion?

Accepted Answer

Surface corrosion

Answer

Filiform corrosion

Answer

Fretting corrosion

Answer

Pitting corrosion

Question 2

When performing a dye penetrant inspection, what is the primary purpose of the developer?

Accepted Answer

To draw the penetrant out of the discontinuity by capillary action, making it visible.

Answer

To clean the surface of the material before applying the penetrant.

Answer

To etch the surface of the material to open up small cracks.

Answer

To remove excess penetrant from the surface after the dwell time.

Question 3

A castellated nut has been torqued to the minimum specified value, but the cotter pin hole does not align with any of the slots. According to standard maintenance practices, what is the correct procedure?

Accepted Answer

Tighten the nut slightly to align with the next available slot, without exceeding the maximum torque value.

Answer

Loosen the nut to the previous slot to align the hole.

Answer

Replace the washer with a thinner one and re-torque.

Answer

Drill a new cotter pin hole in the bolt.

Question 4

Which of the following non-destructive testing (NDT) methods is most suitable for detecting subsurface defects in a non-ferrous material like an aluminum wing spar?

Accepted Answer

Ultrasonic Inspection

Answer

Magnetic Particle Inspection

Answer

Dye Penetrant Inspection

Answer

Eddy Current Inspection

Question 5

During a maintenance task, an AME needs to safety wire a series of three bolts on an engine accessory case. What is the correct procedure for installing the safety wire?

Accepted Answer

The wire should be routed in a way that the tension on the wire counteracts the tendency of the bolt to loosen.

Answer

The wire should be installed so that it pulls the bolt head in the loosening direction.

Answer

A single wire should be used, passing through each bolt head and twisted only at the end.

Answer

No more than two bolts should ever be secured with a single piece of safety wire.

Question 6

An aircraft structural repair requires joining a carbon steel fitting to an aluminum alloy bulkhead. To prevent galvanic corrosion, what is the most critical action the AME must take?

Accepted Answer

Isolate the dissimilar metals with a suitable non-conductive barrier or sealant.

Answer

Apply a thick layer of grease between the two surfaces.

Answer

Use aluminum rivets to attach the steel fitting.

Answer

Ensure a metal-to-metal contact for proper electrical bonding.
