Training, compliance & maintenance for global aviation

Bosio Consulting is an EASA Part-147 approved training and examination centre and a Part-145 maintenance organisation, headquartered in Madrid. We work in four areas: compliance consulting for EASA approvals, Part-147 type training, Part-145 line maintenance with 24/7 AOG support, and technical recruitment, for operators and MROs across Europe, the Middle East and Africa.

Two, both issued and audited by AESA, the Spanish aviation safety agency, under EASA rules: Part-147 approval ES.147.023 for maintenance training and examinations, and Part-145 approval ES.145.281 for aircraft maintenance. Both certificates can be downloaded from our About page.

Both. Courses run at our Madrid training centre, and we deliver on site at your facility when that fits your shift patterns better. Practical elements can be split between the two.

It depends on the scope you apply for and how complete your documentation already is. Send us what you have and what you are applying for, and you get a realistic sequence back rather than a generic timeline.

Our approvals are issued by AESA under EASA rules, so the training and examinations we deliver carry EASA recognition. If you need them accepted by an authority outside EASA, tell us which one and we confirm before you commit to anything.

Yes, and it is a large part of what we do. We read the findings, rewrite what needs rewriting, prepare the post-holders for the follow-up and stay with you through the re-audit.

Barcelona is our Part-145 line maintenance base and the AOG desk is staffed around the clock. For a grounded aircraft, call the desk rather than emailing. You reach an engineer, not a ticket queue.

Both. Technical recruitment is a separate division: licensed engineers and technical crews placed with operators and MROs across Europe, the Middle East and Africa, on a project basis or permanently.

B1 and B2 type and differences training on the Airbus A220, A320 family, A330 and A350, the Boeing 737 NG, 737 MAX and 787, the ATR 42/72 and the Embraer E1 and E2 E-Jets, plus CFM56-7 and V2500 engine run-up simulator courses. Current intakes are listed on our Part-147 course dates page.

Yes. Theory for our Part-147 type courses is delivered online, with the examinations held in the classroom. Our online training store also has self-paced EASA courses, including Human Factors, Fuel Tank Safety, EWIS, Safety Management Systems, Part-IS and cyber security awareness, open 24/7 from €25 with a certificate on completion.

Our headquarters are in Madrid, with offices in Hull in the United Kingdom, Barcelona and Belgrade. Part-145 line maintenance runs at Barcelona-El Prat, Girona-Costa Brava, Paris (Charles de Gaulle area) and Benghazi-Benina, with a Belgrade station opening soon.
