FAA AC 43-9C Advisory Circular is very important to an IA because it details exactly what maintenance records are required, definitions of specific terms, and other important information about maintenance records such as maintaining them by the owner or operator. This AC provides both IA and the owner or operator a common ground for determining what records the owner must provide an IA when IA is accomplishing any required inspection.
FAR 43.11 It details how an IA must certify to the airworthiness, or non-airworthiness of a product undergoing an Annual, or Progressive inspection.
This FAR, together with Far43.15 are the two most important FARs to an IA and the two main FARs under which IAs are violated.
It is recommended that an IA. when signing inspection entries, utilize the exact wording for the entry provided in the FAR.
FAA Order 8900.1 volume 4, chapter 14, section 12 is part of the Airworthiness Inspector’s Handbook.
FAA Order 8900.1 volume 4, chapter 14, section 12 is part of the Airworthiness Inspector’s Handbook. However, its elements are current and applicable. It details items that are considered Powerplant Major Repairs requiring FAA approval. Some of these repairs are in daily use such as welding of cases halves, remachining after weld repairs, and the like. If complex machining operations are necessary, it becomes a Major Repair. When an IA reviews logbooks and discovers powerplant repairs like those mentioned, there should be Form 337 in the aircraft records or a signed workorder as detailed in FAR 43, Appendix B if the repairs were accomplished by an appropriately rated Repair Station.
FAR 45.25 is important to an IA. It details the precise marking requirements on fixed-wing aircraft. While the mis-marking is not an IA inspection item discrepancy, it would be good customer relations to advise the own or operator of the discrepant condition.
