Aviation machinists are trades-people who work in a team or individually to fabricate, repair, rework or modify aircraft parts, components and specialized tooling. They accomplish their work by using complex machinery to maintain the preciseness of the work. They have in-depth knowledge of material working behavior. They must also be familiar with exotic and specialized materials used in the aviation industry. Aviation machinists will work many different materials and many different processes common to the aviation field. They will work extensively with aluminum alloys, titanium, stainless and specialty steels. They will also work with other exotic and composition materials not normally found in the general machining fields.

Aviation machinists must be able to read engineering drawings, and be intuitive to the thought process of developing and carrying out the steps required to machine parts or components. They should be able to think on their feet and be able to use the tools at hand. Many times, machinists are called on in the design phase of a project because of their knowledge of materials, processes and fabrication techniques.

Certification Requirements

To qualify for certification with CCAA, the applicant must possess the necessary knowledge and skills and have acquired a minimum of sixty (60) months in the occupation, or in the tool-making trade (including apprenticeship or other formal training) and practical knowledge of all mandatory tasks in Blocks A, B, C, D, E, F, G and Task 19 in Block I. The tasks in the logbook were made as generic as possible to accommodate the largest amount of work environments and equipment/tools but do not necessarily cover all tasks performed by individuals.

CCAA will apply credit for completion of a CCAA accredited Aviation Machinist course as part of the minimum sixty (60) months, on a month to month basis.
