Category C obtained through the academic route

For category C obtained through the academic route: an applicant holding an academic degree in a technical discipline, from a university or other higher educational institution recognised by the CAA, 3 years of experience working in a civil aircraft maintenance environment on a representative selection of tasks directly associated with aircraft maintenance including 6 months of observation of base maintenance tasks. (Representative selection of tasks should include the observation of hangar maintenance, maintenance planning, quality assurance, record-keeping, approved spare parts control and engineering development).

Nb. There is currently no CAA recognised academic degree and therefore this route is not possible in the UK (August 2024).

Close Category C obtained through the academic route

While an applicant to a Category C licence may be qualified by having 3 years’ experience as category B1 or B2 certifying staff only in line maintenance, it is however recommended that any applicant to a category C holding a B1 or B2 licence demonstrate at least 12 months experience as a B1 or B2 support staff.

The above experience requirement should be practical involving a representative cross section of maintenance tasks on operating aircraft specific to the category to be applied for.

You must complete any training course, basic knowledge examinations and relevant practical maintenance experience within the 10 years preceding the application for an Aircraft Maintenance Licence.

For any application for a Category C licence, it will be expected that the applicant provides evidence of their company authorisation (66.A.30(a)). This should include evidence that they have held an authorisation for the entire period shown in 66.A.30(a). Normally this will involve submission of multiple Part 145 certifying staff authorisation records.

The recommendation document will need to be completed by a Quality Manager or the immediate senior person within the Quality Department of your current employer, or the organisation where the experience is gained.
