Which FAA regulation pertains to maintenance work?

The regulation that specifically addresses maintenance work is Part 43 of the Federal Aviation Regulations (FAR). This part outlines the maintenance, preventive maintenance, and alterations that must be performed on aircraft and appliances to ensure safe operation. It includes the standards for the performance of maintenance work, requirements for maintenance records, as well as the roles and qualifications of those who perform these tasks.

Part 43 is fundamental for ensuring that maintenance procedures are standardized and adhere to safety protocols, which is critical in aviation due to the potential risks involved. It serves as a framework for maintenance practices and specifies the responsibilities of maintenance personnel, aligning with the broader objectives of aviation safety and regulation.

Other parts mentioned, while relevant to aviation regulations, address different areas. For instance, Part 145 deals with repair stations, defining certification and operational standards for entities that provide maintenance services. Part 5 covers safety management systems, which focuses on organizations' overall operational safety rather than specific maintenance activities. Part 14 pertains to the administrative procedures associated with rulemaking, which does not directly involve the technical aspects of maintenance work. Therefore, Part 43 is the primary regulation governing maintenance procedures in aviation.
