Question 1

Why is proper torque application important in aircraft maintenance?

Accepted Answer

To prevent fastener failure and ensure safety

Answer

Proper torque application ensures that fasteners are tightened to their specified tension, creating the necessary clamping force to hold parts together securely. Incorrect torque, whether too loose or too tight, can lead to fastener failure, structural damage, and ultimately compromise the aircraft's safety and airworthiness. Adhering to torque specifications is fundamental for maintaining structural integrity.

Question 2

Which type of fire extinguisher is suitable for electrical fires in aviation?

Accepted Answer

Class C

Answer

Class C fire extinguishers are specifically designed for fires involving energized electrical equipment. They use non-conductive agents like carbon dioxide (CO2) or halon substitutes, which extinguish the fire without posing an electrical shock hazard to the user or damaging sensitive electronics. Using water (Class A) on an electrical fire would be extremely dangerous.

Question 3

What unit is commonly used to measure electrical resistance in aircraft circuits?

Accepted Answer

Ohms

Answer

Ohms are the standard unit of measurement for electrical resistance, quantifying how much a material opposes the flow of electric current. Understanding resistance is fundamental in aircraft circuits to ensure proper component operation, calculate current flow (using Ohm's Law), and prevent overheating or circuit failure. Volts measure potential difference, Watts measure power, and Amperes measure current.

Question 4

Why is FOD (Foreign Object Debris) prevention critical in aircraft maintenance?

Accepted Answer

To prevent damage to aircraft and ensure safety

Answer

Foreign Object Debris (FOD) prevention is critical because even small objects can cause severe damage to aircraft engines, propellers, and control surfaces, especially during takeoff and landing. This damage can lead to costly repairs, operational delays, and, most importantly, catastrophic safety incidents. Strict FOD control measures are essential to maintain aircraft safety and operational readiness.

Question 5

Which aircraft document lists required inspections and maintenance intervals?

Accepted Answer

Maintenance manual

Answer

The aircraft's maintenance manual is the authoritative document provided by the manufacturer that details all required inspections, maintenance procedures, and their specific intervals. It contains comprehensive instructions for servicing, troubleshooting, and repairing the aircraft. Adhering to these guidelines is essential for maintaining the aircraft's airworthiness and operational safety.
