Principle
To certify maintenance on an aircraft in group 1 (and, as applicable, group 2), a B1, B2 or C licence holder must hold the relevant type rating endorsed on the licence (66.A.45).
Type training has a theoretical and a practical element. Its levels and content are defined in Appendix III to Part-66. It is generally delivered by a Part-147 organisation or approved by the authority.
On-the-job training (OJT)
For a first type rating within a given category or subcategory, on-the-job training is required. It takes place in a maintenance organisation, under supervision, and covers a representative cross-section of tasks.
Practical tips
- Check that the training certificate states the category covered (B1, B2, C) and the engine variant.
- Keep theoretical, practical and OJT certificates together for the endorsement application.
- Plan the time between course completion and application: the regulation sets a validity period.
Frequently asked questions
Is type training enough to certify?
It allows the rating to be endorsed on the licence. Certifying also requires a certification authorisation from the organisation and compliance with recent experience requirements.
