WHAT YOU WILL LEARN

Part 145 approval ensures that maintenance organizations have the capability to perform maintenance tasks safely and effectively, maintaining the airworthiness of aircraft and contributing to the overall safety and reliability of aviation operations. It also involves regular audits and inspections by regulatory authorities to ensure continued compliance with the established standards.

The organization and its staff must be capable of performing the maintenance work. This not only comprises sufficient staff for planning and execution but also monitoring and quality assurance, as well as personnel for Non-Destructive Testing (NDT).

The organization must ensure that adequate facilities (offices, hangers, and back shops) are available. This comprises the availability of suitable storage capacities for components equipment and materials, as well as tools. A controlled work environment (cleanliness, lighting, noise, humidity, temperature) must be ensured.

A maintenance organization must have the necessary equipment, tools, and materials to perform the approved scope of work. These should normally be permanently available. It must be ensured that the operational equipment and tools are regularly checked, and calibrated.

All work must be performed on the basis of approved maintenance data. The maintenance documentation comprises regulatory requirements, design data of the design approval holder, as well as specific customer requirements. These requirements may only be deviated from, if the party that issued the respective data approved such deviation.

Maintenance organizations are entitled to perform maintenance work at the locations designated, according to the scope of approval, and in exceptional cases to provide worldwide line maintenance. This also includes the release to service of aircraft and components after accomplished maintenance.
