Free A&P General Aircraft Maintenance Practices & Regulations Questions and Answers

Question 1

What is the purpose of a 100-hour inspection?

Accepted Answer

To comply with FAA regulations for commercial aircraft

Answer

A 100-hour inspection is a mandatory maintenance requirement specifically for aircraft that are used for hire or flight instruction, as stipulated by FAA regulations (14 CFR Part 91.409(b)). This inspection ensures that aircraft operating commercially maintain a high standard of airworthiness and safety due to their frequent use. It is similar in scope to an annual inspection but is tied to operational hours rather than calendar months.

Question 2

Which document specifies maintenance requirements for a specific aircraft?

Accepted Answer

Aircraft Maintenance Manual

Answer

The Aircraft Maintenance Manual (AMM) is the definitive document provided by the aircraft manufacturer, containing detailed instructions for all maintenance, inspection, troubleshooting, and repair procedures specific to that aircraft model. It ensures that maintenance is performed correctly and consistently, which is essential for maintaining the aircraft's airworthiness and compliance with design specifications. Other documents like the Pilot's Operating Handbook serve different operational purposes.

Question 3

What is the primary purpose of an Airworthiness Directive (AD)?

Accepted Answer

To mandate corrective action for safety issues

Answer

Airworthiness Directives (ADs) are legally binding regulations issued by the FAA (or other national aviation authorities) to correct unsafe conditions found in aircraft, engines, propellers, or components. They mandate specific inspections, repairs, or modifications that must be performed to ensure continued airworthiness and prevent potential accidents. Compliance with all applicable ADs is mandatory for an aircraft to be considered airworthy and legally flown.

Question 4

Which tool is essential for measuring torque during maintenance?

Accepted Answer

Torque wrench

Answer

A torque wrench is an indispensable tool in aircraft maintenance used to apply a precise and specified amount of rotational force (torque) to fasteners. Applying the correct torque is critical to prevent fasteners from loosening due to vibration or from being over-tightened, which could cause structural damage or material fatigue. This ensures the integrity and safety of all assembled aircraft components.

Question 5

What must be done before performing maintenance on aircraft systems?

Accepted Answer

Disconnect all relevant power sources

Answer

Before commencing any maintenance on aircraft systems, it is absolutely essential to disconnect all relevant power sources, such as battery connections or circuit breakers. This critical safety measure prevents accidental activation of systems, protects mechanics from electrical shock, and prevents potential damage to sensitive aircraft components. It is a fundamental safety protocol in aviation maintenance.
