An industry in three main links
Behind the word "aerospace" there are three worlds that offer neither the same tasks nor the same internship status.
- Design and testing: design offices, structural calculation, on-board systems, flight or ground tests. The profiles are mostly at three to five years of higher education.
- Production: machining, assembly, wiring, composite materials, surface treatments, dimensional inspection. Recruitment starts at CAP or vocational baccalaureate level.
- Maintenance: line maintenance at airports, heavy checks in the hangar, overhaul of engines and equipment at specialists.
On top of this come the support functions: quality, logistics, purchasing, methods, document management. A management or logistics student can also find an internship there, which widens the field considerably.
Training routes that open the door
For the workshop and the flight line, vocational qualifications dominate: the vocational baccalaureate in the aerospace sector (systems, avionics and structure options), supplementary certificates, and the BTS in aerospace maintenance or manufacturing. For design offices and test laboratories, you are more likely to meet the BUT, professional bachelor's degrees, master's degrees and engineering degrees, some of which can be taken as an apprenticeship.
Aircraft maintenance falls under a European framework: carrying out certain certification tasks requires a maintenance technician licence issued under precise rules, with examinations and practical experience. An internship or apprenticeship contract counts towards the path, but does not replace those conditions.
If you hesitate between several routes, compare the programmes, the presence of equipped teaching workshops and the partner companies. A visit on an open day often tells you more than a brochure.
Internship or work-study: two logics not to mix up
An internship is based on an agreement between you, your institution and the company. It lasts from a few weeks to several months. In France, beyond two months a payment (gratification) is provided for; check the amount with your institution, since it changes with the regulations.
An apprenticeship or professionalisation contract is an employment contract: salary, holiday, contributions, alternating between company and training centre. The big prime contractors and their subcontractors offer them, but the recruitment calendar starts early, often several months before the start of the academic year.
When you look through the offers, check the status advertised: an internship advert does not lead to a work-study contract, and vice versa. A candidate who applies under the wrong heading wastes time and sends a signal of disorganisation.
Traceability: the discipline that sets aerospace apart
In this industry, a part only really exists if its history is documented: serial number, material batch, operator, tool used, inspection result, date. This traceability makes it possible to find the origin of a defect and act on an entire series. Companies apply demanding quality standards, and their customers audit them regularly.
For an intern, this translates into concrete reflexes: write legibly, sign only what you have done, never correct a value without a note, put parts in the right bins, report any anomaly. An intern is not authorised to certify an operation, but can keep records under supervision.
A good internship here looks less like a series of spectacular actions than like learning rigour. That quality then carries over into all your future posts.
Possible tasks depending on the department
Design office and methods
Modelling parts, updating drawings, preparing manufacturing routings, analysing non-conformities. You are expected to master design software and to write precisely.
Production workshop
Assembling sub-assemblies, fitting fasteners, wiring, visual and dimensional inspection, following manufacturing files.
Quality and inspection
Taking dimensional readings, recording results, taking part in audit preparation, following up corrective actions.
Maintenance
Helping with inspection operations, removal and refitting under supervision, preparing work documents, managing calibrated tooling.
Site access: plan the formalities ahead
Aerospace establishments, especially those involved in defence or restricted airport zones, apply strict access rules. These may include an administrative background check, a badge to be requested several weeks in advance, identity documents to supply, and restrictions on phones or cameras.
These procedures explain why some companies reply late or ask for unusual documents. They may also set conditions on nationality or residence, depending on the nature of the site. Ask the question in advance, rather than waiting for the day before you start, and keep copies of your documents.
Also plan your transport: many sites are far from town centres, and workshop hours start early. Nearby housing or a car share can decide whether an internship is feasible.
Illustration: a realistic application timeline
A fictional example, with rounded landmarks. A BTS student is looking for a work-study contract starting in September. In October she identifies ten companies: a large manufacturer, two equipment suppliers, three small subcontracting firms and four maintenance workshops. In November she sends her applications, each tailored to the department targeted. In January she has two interviews. In March an offer is confirmed, and then the wait for the access formalities begins.
Had she waited until June, she would have had to find an employer within a few weeks, with no margin for the administrative steps. This scenario is not a rule, but it shows why the sector rewards anticipation. Always keep a plan B: a regional small firm may offer more versatility than a large, highly specialised site.
Applications and common mistakes
A recruiter in the industry looks for candidates who understand what is at stake with reliability. On your CV, cite your technical projects, your software, your measurements and anything that demonstrates rigour in your work. At interview, explain how you go about checking a result before passing it on.
- Talking only about a passion for aircraft without mentioning quality and safety constraints.
- Applying without saying which link you are aiming for: design, production or maintenance.
- Neglecting technical English: documentation and exchanges are frequently written in English.
- Underestimating the time needed for authorisations and site access.
- Believing that an internship gives the right to sign off an operation: certification remains reserved for authorised personnel.
Frequently asked questions
Do you need to love flying to work in aerospace?
No. Most jobs take place in a factory, a design office or a hangar. An interest in mechanics, electrics, materials or quality is enough. Piloting is a separate profession, with its own routes and certificates, and has no direct link with the internships described here.
What level of English is expected?
It varies by post, but technical documentation, standards and many exchanges with customers are in English. A reliable understanding of technical terms is an asset, even for a workshop post. You can show it through a test, a certificate or time spent abroad.
Can an intern sign an inspection sheet?
Generally not. The signature engages the responsibility of the person authorised by the company or maintenance organisation. The intern can record values and prepare the file under supervision, but final validation belongs to an authorised operator. Ask from the start what you are allowed to do.
How do you land a work-study place at a large manufacturer?
Apply early, tailor your application to the department targeted, and follow the channel indicated in the advert. Large groups receive many requests; previous experience, even brief, or a concrete technical project can set you apart. Also pursue several leads among subcontractors.
Can access formalities block an internship?
They can delay or prevent access to certain sites, particularly in defence. The delay varies with the company and the level of clearance required. Provide the documents requested quickly and avoid planning a move before you have written confirmation.
Can you work in aerospace with a CAP?
Yes, notably in production, assembly or certain maintenance operations under supervision. Progression remains possible through continuing training, validation of prior experience or work-study towards a vocational baccalaureate or a BTS. How far you go depends on the company and your career path.
How do you choose between a small firm and a large group?
A large group offers a strong name, structured career paths and advanced tools, but tasks are sometimes narrowly defined. A small firm often gives more varied tasks and direct contact with management. The right choice depends on what you want to learn.
