What must be confirmed before returning an aircraft to service after major repairs?
Answer: Compliance with airworthiness standards
Before an aircraft can be returned to service after major repairs, it is essential to confirm its compliance with all applicable airworthiness standards. An Inspection Authorization (IA) holder must ensure that the repairs meet the original type design, all relevant Airworthiness Directives (ADs), and regulatory requirements. This rigorous verification guarantees the aircraft's structural integrity and safe operational capability.
Which document must be issued by an IA for return to service after an annual inspection?
Answer: Return to Service Logbook Entry
For an aircraft to be returned to service after an annual inspection, an IA must issue a Return to Service Logbook Entry. This entry, detailed in 14 CFR Part 43.11, serves as the official certification that the aircraft has been inspected and found to be in an airworthy condition. It includes a description of the inspection, the date, and the IA's signature and certificate number.
What is the role of an IA in determining airworthiness?
Answer: Determines compliance and safe condition
The primary role of an Inspection Authorization (IA) holder in determining airworthiness is to meticulously inspect an aircraft to determine its compliance with all applicable regulations and ensure it is in a safe condition for flight. IAs are authorized to perform annual inspections and approve major repairs and alterations, acting as a critical safeguard for aviation safety.
Which part of the CFR governs return-to-service procedures?
Answer: 14 CFR Part 43
14 CFR Part 43, titled "Maintenance, Preventive Maintenance, Rebuilding, and Alteration," specifically governs the procedures for returning an aircraft to service. This part outlines the requirements for performing maintenance, making appropriate record entries, and the qualifications needed to approve an aircraft for flight after maintenance or inspection.
What is required in a maintenance entry for return to service?
Answer: Work summary and FAA certificate number
A maintenance entry for return to service must include a comprehensive work summary and the FAA certificate number of the person performing the work. As per 14 CFR Part 43.9, this entry must detail the work performed, the date of completion, the name of the person, and their certificate number and type, ensuring accountability and a clear record of maintenance.
Who has the authority to approve an aircraft for return to service after a major alteration?
Answer: Mechanic with IA
Only a mechanic holding an Inspection Authorization (IA) or an appropriately rated repair station has the authority to approve an aircraft for return to service after a major alteration. This ensures that the alteration has been performed in accordance with approved data and meets all applicable airworthiness standards, maintaining the aircraft's safety and integrity.
