Aircraft maintenance engineering is one of the most skilled and respected professions in aviation — and one of the most in-demand. With a global shortage of qualified engineers, strong salaries, and opportunities to work internationally, it’s a career path that offers real long-term reward for those with the aptitude and commitment to see it through.
At Protec Technical, we’ve worked with engineers at every stage of this journey since 2003. Whether you’re just starting out or looking to take the next step, this guide maps out what a career in aircraft maintenance engineering typically looks like.
Starting Out: Education and Entry Routes
There is no single entry route into aircraft maintenance engineering, which means the profession is accessible from a variety of starting points. The most common routes include:
- Apprenticeships – Many airlines, MRO providers, and defence organisations offer aircraft maintenance apprenticeships at Level 3 (A-level equivalent) and degree-level. These typically last three to four years and combine on-the-job training with structured learning. Participants emerge with both practical experience and the theoretical grounding needed to progress towards Part-66 licensing.
- Further Education – BTEC or equivalent qualifications in aerospace engineering provide a foundation for entry into the sector, often leading into apprenticeship or trainee technician roles.
- Military Routes – A significant number of aircraft maintenance engineers in the civilian sector have backgrounds in the armed forces, where they may have trained as aircraft technicians or aeronautical engineers. Military experience is highly regarded in the civilian MRO world.
- Degree Entry – An engineering degree (aerospace, mechanical, electrical) may allow accelerated progression towards a Part-66 Category C licence, bypassing some experience requirements applicable to other routes.
Trainee Technician: Building the Hours
The first few years of a maintenance engineer’s career are typically spent as a trainee or junior technician, working under the supervision of licensed engineers. This period is crucial for accumulating the practical experience — typically measured in months working on operating aircraft — required for licence applications.
During this phase, the focus is on breadth of exposure: working across different aircraft types and systems, understanding the maintenance documentation environment (AMMs, SRMs, CMMs, engineering orders), and developing the discipline and precision that underpin everything in aircraft maintenance.
Part-66 Examinations: The Licensing Pathway
Alongside accumulating experience, aspiring licensed engineers must pass the relevant Part-66 modular examinations. Most engineers pursuing a B1.1 licence (the most common for those working on commercial turbine-powered aircraft) need to pass around 17 modules, though the exact number depends on the licence subcategory and any applicable exemptions.
Many choose to study through an approved training organisation (ATO). Courses range from classroom-based programmes to online self-study packages, and preparation typically takes two to four years alongside full-time work. Discipline and consistency matter more than any natural talent — this is a qualification earned through sustained effort.
Obtaining Your Basic Licence
With examinations passed and experience documented, engineers apply to their relevant national aviation authority (in the UK, the Civil Aviation Authority; in EU member states, the relevant national authority) for the basic Part-66 licence. This is a significant milestone — it confirms the holder’s competence and allows them to begin working towards full certifying staff privileges.
A basic licence without type ratings, however, has limited immediate application. The next priority is gaining type experience and, ultimately, a type rating on aircraft the engineer will be working on.
Type Ratings and Certifying Privileges
Type ratings are added to a Part-66 basic licence following approved type training (typically a two-week manufacturer-approved course) and a defined period of on-type experience, usually supervised by an existing type-rated engineer. Once the experience requirement is met, the engineer can apply to have the type rating added to their licence and begin exercising certifying privileges on that type.
For many engineers, the first type rating is the most significant career stepping-stone. From this point, progression involves accumulating experience, adding further type ratings, and — for those with the inclination and aptitude — moving towards team leader, quality, and management roles.
Beyond the Hangar Floor: Management and Specialist Roles
Aircraft maintenance engineering is not a one-dimensional career. Experienced engineers progress into roles including shift supervisor, quality inspector, NDT specialist, planning engineer, technical services engineer, maintenance controller, and ultimately into management positions such as maintenance manager, quality manager, or CAMO (Continuing Airworthiness Management Organisation) manager.
Each of these specialisms carries its own training and qualification requirements, and each offers a distinct career trajectory. The aviation sector values deep technical expertise and rewards those who invest in developing it.
