The licensed engineer who signs a certificate of release to service is doing something no pilot, manager or inspector can do in their place: legally returning an aircraft to flight. That signature is the whole career. Everything in the UAE aircraft maintenance path, the training, the module exams, the years of hands-on experience, the type ratings, exists to get you to the point where your name can go in that box, and then to widen the range of aircraft you can put it against.

This is how the licensed engineer path works under the UAE GCAA's CAR-66 framework in 2026, what each licence category lets you do, what the journey takes, and what it pays.

The categories are the map

CAR-66, the UAE's equivalent of the well-known EASA Part-66 system, divides the aircraft maintenance engineer licence into categories, and the category defines what you are legally allowed to certify. Getting this right early matters, because it determines the training you take and the jobs you can hold.

Category A, line certifying mechanic. Authorises certification of simple, specified line-maintenance tasks and straightforward defect rectification, within the limits of the tasks on your authorisation. It is the narrowest scope and the entry to certifying work.

Category B1, mechanical. The airframe-and-powerplant licence. It authorises certification of line and base maintenance on aircraft structure, engines, and mechanical and electrical systems. B1 is the backbone licence for most heavy-metal maintenance work and is subdivided by aircraft type, turbine aeroplanes being the relevant one for airline work.

Category B2, avionics. The electrical and avionics licence, covering the aircraft's electrical and electronic systems. As aircraft become more systems-heavy, B2 holders are increasingly in demand in their own right.

Category C, base maintenance. The licence that allows certification of a large aircraft after base maintenance, issuing the release to service at the whole-aircraft level. It is typically reached either through a relevant degree route or by building up from a B licence, and it sits at the senior end of the certifying hierarchy.

For most people aiming at an airline or MRO career on large aircraft, B1 or B2 is the target licence, and the choice between them is the choice between mechanical and avionics specialisation.

The journey to the first signature

Getting licensed is a sequence, and none of the steps can be skipped.

Basic training and examinations. You work through the CAR-66 basic knowledge modules, a substantial theoretical syllabus of around seventeen modules, with written examinations, usually at a CAR-147-approved training organisation. This is the classroom foundation and it is category-specific.

Experience. The regulation requires documented hands-on maintenance experience before the licence is issued, and the amount depends on category and on whether you completed an approved course. This is the part that cannot be rushed, because it is measured in years of real work on real aircraft, not in exam passes.

The first type rating and on-the-job training. A basic licence lets you certify very little on its own. To certify a specific aircraft type you add a type rating, and the first type rating requires structured on-the-job training, completing at least half of the regulatory task list under supervision within the three years before you apply. Up to half of that OJT can be done before the theoretical type course. This first type is the hardest and most involved to earn.

Additional type ratings. Once you hold your first type in a category, adding further types is lighter. Subsequent ratings are based on a training-need analysis rather than a full OJT programme, which is why an established engineer can broaden across types far faster than they earned the first one.

What it pays, and what moves the number

UAE maintenance pay is tax-free, and it climbs steeply with certification and type ratings, because the licence and the ratings are exactly what an employer is paying for.

An unlicensed or newly qualified technician, before full certifying privileges, typically earns in the range of AED 8,000 to 15,000 a month. Once you hold full B1 or B2 certifying privileges with type ratings on in-service aircraft, monthly earnings commonly rise to around AED 25,000 to 28,000, roughly AED 240,000 to 340,000 a year with allowances and overtime. Across the market as a whole, licensed engineer packages span broadly from around AED 120,000 to AED 300,000 a year depending on category, type ratings, employer and experience.

The pattern is clear and it should shape decisions: the money is in the licence and the type ratings, not in years served as such. Two engineers with the same tenure can sit far apart on pay if one holds current certifying privileges on the right aircraft and the other does not.

Which type ratings are worth chasing

Demand concentrates in two places in the UAE.

The large airline fleets, widebodies such as the A380 and Boeing 777, generate steady demand for B1 and B2 engineers type-rated on the metal the major carriers actually fly. And the region's substantial business-aviation sector adds strong demand for engineers rated on high-end private jets, with Gulfstream, Dassault, Bombardier and Embraer types recurring in UAE job postings, the Gulfstream G600, G650 and G700 among the most frequently sought.

The strategic point for an engineer is that a type rating is a market position. Holding current ratings on aircraft that are widely operated in the UAE, whether widebody airliners or in-demand business jets, is what keeps you both employable and expensive.

How to build the career deliberately

Choose the category before you start, because B1 mechanical and B2 avionics lead to different training and different jobs, and switching later is costly. Complete the basic exams through an approved organisation and be patient with the experience requirement, because it is a legal floor that cannot be shortcut. Treat the first type rating as the major hurdle it is, then use the lighter path for additional types to broaden your marketability fast. And target type ratings on aircraft with real UAE demand, because the ratings you hold, more than the years you have logged, are what set your pay.

A note on sourcing

Licence category scope and the outline of the licensing journey here reflect the UAE CAR-66 framework and the closely aligned EASA Part-66 system; the GCAA publishes CAR-66 in full and it is the authoritative reference for exact experience durations and current procedure. Salary ranges are drawn from 2026 UAE market and recruitment sources and vary with employer, type ratings and overtime.
