In a JAR-145 maintenance organization, which language(s) must certifying staff be able to use?

In a JAR-145 maintenance organization, certifying staff are required to be proficient in the language in which documents and procedures are written, as well as the language generally spoken within the organization. This requirement ensures effective communication and understanding of important documentation, which is critical for maintaining safety and compliance in aviation maintenance.

The ability to comprehend and accurately interpret technical manuals, maintenance procedures, and regulatory instructions in the relevant language ensures that the staff can perform their duties effectively. Moreover, proficiency in the spoken language within the organization facilitates clear communication among team members, enhancing collaboration and reducing the risk of misunderstandings that could lead to errors.

Adhering to this requirement not only supports compliance with regulatory standards but also promotes a more competent workforce capable of addressing issues that may arise during maintenance activities. This is particularly important given the specialized nature of aviation work, where precision and clarity are paramount.
