When performing a borescope inspection of an aircraft engine cylinder, the technician is primarily looking for:
Answer: Cylinder wall scoring, corrosion, and valve condition
Borescope inspections reveal internal cylinder conditions such as scoring, corrosion, carbon deposits, and valve seat condition without engine disassembly.
An aircraft technician uses a cleco fastener during sheet metal assembly primarily to:
Answer: Temporarily hold drilled sheets in alignment while additional holes are drilled
Cleco fasteners snap into drilled holes and clamp sheets together temporarily, maintaining alignment as additional holes are drilled and deburred.
The purpose of a heat gun used in aircraft maintenance is best described as:
Answer: Providing controlled heat for tasks such as heat-shrink tubing installation and adhesive removal
Heat guns deliver regulated hot air for shrinking heat-shrink tubing, removing decals, softening adhesives, and similar low-temperature thermal tasks.
When calibrating a pressure gauge used for aircraft oxygen system testing, the reference standard should be:
Answer: A certified, NIST-traceable master gauge of higher accuracy
Calibration requires a reference standard traceable to NIST (or equivalent national standard) with higher accuracy than the instrument being calibrated.
A bench grinder in the aircraft maintenance shop should have eye shields and tool rests because:
Answer: They protect technicians from sparks and fragments and support workpieces to prevent gouging the wheel
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.
Which tool is used to check that a drilled rivet hole meets the minimum edge distance requirement?
Answer: A steel rule or rivet pitch gauge
A steel rule or rivet spacing/pitch gauge is used to measure from the hole center to the sheet edge to verify compliance with minimum edge distance requirements in the applicable SRM.
When using a compression tester on an aircraft reciprocating engine cylinder, air pressure is applied while the piston is:
Answer: At top dead center (TDC) on the compression stroke with both valves closed
The differential compression test requires the piston at TDC on the compression stroke so both intake and exhaust valves are closed, allowing leakage to be measured accurately.
