Aircraft Maintenance Inspection & Troubleshooting

Question 1

What is the primary purpose of a pre-flight inspection in aircraft maintenance?

Accepted Answer

To verify airworthiness and safety before flight

Answer

The primary purpose of a pre-flight inspection in aircraft maintenance is to verify the airworthiness and safety of the aircraft before each flight. This critical procedure involves a thorough visual and functional check of key systems and components to ensure they are in proper working order, confirming the aircraft's readiness for safe operation.

Question 2

Which instrument is commonly used for detecting cracks in aircraft structures?

Accepted Answer

Eddy current tester

Answer

An eddy current tester is a non-destructive testing (NDT) instrument commonly used in aircraft maintenance to detect surface and subsurface cracks, corrosion, and other discontinuities in conductive materials like aluminum alloys. It works by inducing eddy currents in the material and detecting changes caused by flaws, making it essential for structural integrity checks.

Question 3

What is the recommended action when an aircraft engine experiences abnormal vibration during operation?

Accepted Answer

Shut down the engine and inspect for faults

Answer

Abnormal engine vibration during operation is a serious indication of a potential mechanical fault that could lead to catastrophic failure. The recommended action is to immediately shut down the engine (if safe to do so) and conduct a thorough inspection to identify and rectify the underlying cause, prioritizing safety above all else.

Question 4

Which type of corrosion is most commonly found on aluminum aircraft structures?

Accepted Answer

Pitting corrosion

Answer

Pitting corrosion is a localized form of corrosion that creates small holes or pits on the surface of a metal, commonly found on aluminum aircraft structures. It is particularly dangerous because it can penetrate deeply into the material, significantly weakening the structure even with minimal visible surface damage, making it a critical concern in aircraft maintenance.

Question 5

What is the function of a borescope in aircraft maintenance?

Accepted Answer

To inspect internal aircraft components without disassembly

Answer

A borescope is an optical instrument used in aircraft maintenance to visually inspect internal components of engines, airframes, and other systems without requiring extensive disassembly. This non-destructive inspection method saves significant time and cost while allowing technicians to identify potential issues like cracks, wear, or foreign object damage in hard-to-reach areas.
