The Category C licence permits the release of an
aircraft to service in its entirety by a single certificate of
release to service by one overall signatory, once all
base maintenance work and checks have been
completed in accordance with Part-145. The Category
C licence certifier will act primarily in a maintenance
management role controlling the progress of aircraft
maintenance work. A Category C licence alone does
not permit the holder to act as a B1 or B2 certifier.
An applicant for a category C licence must have
completed a prescribed period of aircraft maintenance
experience. The Category C licence may be obtained
via one of two available routes: either by experience
gained through holding a Category B1 or B2 licence, or
as a graduate entrant with a degree that is considered
to be acceptable to the CAA.
Large Aircraft
3 years experience exercising B1.1, B1.3 or B2
privileges on large aircraft or as Part-145 B1.1, B1.3 or
B2 support staff, or a combination of both.
5 years experience exercising B1.2 or B1.4 privileges
on large aircraft or as Part-145 B1.2 or B1.4 support
staff, or a combination of both.
Non Large Aircraft
3 years experience exercising B1 or B2 privileges on
non- large aircraft or as Part-145 B1 or B2 support staff,
or a combination of both.
Graduate Route
A graduate holding a degree in Aeronautical
Engineering, or a similar discipline that is considered by
the CAA relevant to aircraft maintenance that has been
accepted for this purpose by the CAA, must have at
least 3 years experience in a civil aircraft maintenance
environment including 6 months of observation of base
maintenance tasks. There are currently no standard
assessment terms for these applications and therefore
applicants are advised, before applying for licence
issue, to ensure they meet the experience criteria in
accordance with Part-66.A.30 and related AMC. A
person qualifying for a Category C licence via this route
will not be entitled to a Category B1 or B2 licence
unless the requirements for those Categories are also
met.
