Appendix A for continued airworthiness is associated with which Part?

• A. Part 21
• B. Part 23
• C. Part 27
• D. Part 39

Answer: (C)

Continued airworthiness covers the ongoing maintenance, inspections, and documentation needed to keep an aircraft safe and compliant after it’s certified. For rotorcraft, the regulations that address these continued airworthiness requirements are found in Part 27, and specifically in Appendix A of that part. This appendix lays out the procedures, inspection intervals, and maintenance actions required to maintain rotorcraft in an airworthy condition, including how service information and life-limited parts are managed. Part 21 governs certification procedures for products and parts, Part 23 covers airworthiness standards for normal and utility airplanes (and some others), and Part 39 deals with Airworthiness Directives. None of those sections contain the rotorcraft-focused continued airworthiness provisions that Appendix A of Part 27 provides, which is why Part 27 is the best fit.
