Question 1

When performing a borescope inspection of an aircraft engine cylinder, the technician is primarily looking for:

Accepted Answer

Cylinder wall scoring, corrosion, and valve condition

Answer

Borescope inspections reveal internal cylinder conditions such as scoring, corrosion, carbon deposits, and valve seat condition without engine disassembly.

Question 2

An aircraft technician uses a cleco fastener during sheet metal assembly primarily to:

Accepted Answer

Temporarily hold drilled sheets in alignment while additional holes are drilled

Answer

Cleco fasteners snap into drilled holes and clamp sheets together temporarily, maintaining alignment as additional holes are drilled and deburred.

Question 3

The purpose of a heat gun used in aircraft maintenance is best described as:

Accepted Answer

Providing controlled heat for tasks such as heat-shrink tubing installation and adhesive removal

Answer

Heat guns deliver regulated hot air for shrinking heat-shrink tubing, removing decals, softening adhesives, and similar low-temperature thermal tasks.

Question 4

When calibrating a pressure gauge used for aircraft oxygen system testing, the reference standard should be:

Accepted Answer

A certified, NIST-traceable master gauge of higher accuracy

Answer

Calibration requires a reference standard traceable to NIST (or equivalent national standard) with higher accuracy than the instrument being calibrated.

Question 5

A bench grinder in the aircraft maintenance shop should have eye shields and tool rests because:

Accepted Answer

They protect technicians from sparks and fragments and support workpieces to prevent gouging the wheel

Answer

Eye shields protect technicians from flying sparks and wheel fragments, while properly adjusted tool rests support the workpiece and prevent it from catching on the wheel.
