Aircraft Inspection Procedures & Documentation Flashcards

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

Answer: To verify the aircraft's airworthiness before flight

A pre-flight inspection, often referred to as a 'walk-around,' is a mandatory visual and functional check performed by the pilot before every flight. Its primary purpose is to verify that the aircraft is in a safe and airworthy condition, free from any obvious defects or malfunctions that could compromise flight safety. This includes checking critical components like fuel levels, oil, flight controls, and external surfaces.

Which inspection is required for all civil aircraft at least once every 12 calendar months?

Answer: Annual inspection

The annual inspection is a comprehensive and in-depth inspection required by FAA regulations (14 CFR Part 91.409(a)) for all civil aircraft at least once every 12 calendar months. This inspection must be performed by an A&P mechanic holding an Inspection Authorization (IA). Its purpose is to ensure the aircraft conforms to its type design and is in a condition for safe operation, thus maintaining its airworthiness.

What document must be completed after any maintenance or inspection?

Answer: Aircraft maintenance log

The aircraft maintenance log, often referred to as the aircraft logbook, is the official and legal record where all maintenance, inspections, repairs, and alterations performed on an aircraft are documented. After any work is completed, a detailed entry must be made, including the date, a description of the work, and the signature and certificate number of the approving mechanic. This documentation is crucial for ensuring airworthiness and regulatory compliance.

What is the purpose of a conformity inspection?

Answer: To verify modifications meet approved standards

A conformity inspection is conducted to verify that an aircraft, component, or modification physically matches its approved design data, drawings, and specifications. This inspection is particularly important after major repairs or alterations, or during the manufacturing process, to confirm that the actual product conforms precisely to the certified design and regulatory requirements. It ensures the aircraft's continued airworthiness and safety.

Which inspection method uses high-frequency sound waves to detect flaws?

Answer: Ultrasonic testing

Ultrasonic testing (UT) is a non-destructive inspection (NDI) method that uses high-frequency sound waves to detect internal flaws, cracks, or discontinuities within materials. The sound waves are transmitted into the material, and reflections (echoes) are analyzed to identify defects without causing damage to the component. This makes UT highly effective for inspecting critical aircraft structures and components for hidden damage.

What must be checked during a landing gear inspection?

Answer: Wear, leaks, and proper operation

During a landing gear inspection, mechanics must thoroughly check for signs of wear on components like tires, brakes, and struts, identify any hydraulic fluid leaks, and verify the proper operation of the retraction/extension mechanism. Additionally, landing gear lights and warning systems must be checked for functionality. This comprehensive inspection ensures the gear can safely support the aircraft during ground operations and withstand landing stresses.

What is required for an aircraft to be considered airworthy?

Answer: Proper maintenance and compliance with type design

For an aircraft to be considered airworthy, it must meet two fundamental conditions: it must conform to its type design (meaning it matches the original approved design, including any approved modifications) and be in a condition for safe operation (meaning it has been properly maintained and is free from defects). Both aspects are crucial for ensuring the aircraft can be operated safely and legally.

Which document specifies inspection procedures for a particular aircraft model?

Answer: Aircraft inspection manual

The Aircraft Inspection Manual, often integrated within or referenced by the broader Aircraft Maintenance Manual, specifically details the step-by-step procedures, checklists, and criteria for performing various inspections on a particular aircraft model. It ensures that inspections are thorough, consistent, and compliant with manufacturer and regulatory requirements, thereby identifying potential issues and maintaining the aircraft's airworthiness. This manual is essential for mechanics conducting routine and special inspections.

What is the purpose of a service bulletin compliance record?

Answer: To track compliance with manufacturer recommendations

Service bulletins are issued by aircraft manufacturers to address potential safety issues, improve performance, or recommend maintenance procedures. A compliance record ensures that these critical recommendations are followed, maintaining the airworthiness and safety of the aircraft. This documentation is vital for regulatory oversight and demonstrating due diligence in aircraft maintenance.
