Get Part 43 Appendix D

This is because, ing to the regulations, only a certified avionics repair station can perform the transponder and altimeter portion of the inspections (A&Ps are permitted to do a simple static leak check following maintenance on the system).

So, although Part 43 does not apply to aircraft with an experi- mental certificate, it does apply to those aircraft with a new light sport aircraft certificate. What's Covered in Part 43?

§ 91.413 ATC transponder tests and inspections. (b) Following any installation or maintenance on an ATC transponder where data correspondence error could be introduced, the integrated system has been tested, inspected, and found to comply with paragraph (c), appendix E, of part 43 of this chapter.

Appendix E to Part 43 - Altimeter System Test and Inspection. Each person performing the altimeter system tests and inspections required by § 91.411 of this chapter must comply with the following: (a) Static pressure system: (1) Ensure freedom from entrapped moisture and restrictions.

The ATC transponder tests required by § 91.413 of this chapter may be conducted using a bench check or portable test equipment and must meet the requirements prescribed in paragraphs (a) through (j) of this appendix.

Appendix D to Part 43—Scope and Detail of Items (as Applicable to the Particular Aircraft) To Be Included in Annual and 100-Hour Inspections. (a) Each person performing an annual or 100-hour inspection shall, before that inspection, remove or open all necessary inspection plates, access doors, fairing, and cowling.

The purpose of part 43 is to ensure that an aircraft is “airworthy” after work has been performed. Part 145 sets forth safety standards necessary to inspect and maintain aircraft and aircraft parts. These safety standards ultimately benefit the maintenance personnel, passengers, and flight crew.
