What is EASA Part 147?

What it means in practice

Part-147 is the training-organisation side of the maintenance licensing system. It controls the environment in which approved maintenance training and examinations are delivered. That includes facilities, instructional staff, examination control, records, and the conduct of approved training courses.

In practice, Part-147 does not issue the Part-66 licence. It provides approved training and examinations that support the licence pathway. The licence itself sits in Part-66 and is issued by the competent authority under the applicable process.

Who it applies to

Part-147 applies to organisations that want approval to provide Part-66 basic training, examinations, or type training within the maintenance licensing framework. It affects training managers, instructors, examiners, and compliance staff inside approved maintenance training organisations.

It also affects maintenance organisations and licence applicants because Part-147 approvals shape which training and examination credits are acceptable inside the licensing pathway.

What EASA says

The rule set addresses facilities, personnel, instructional equipment, records, examination integrity, and approved courses. The clauses most often used in practice are 147.A.100 on facility requirements, 147.A.105 on personnel requirements, 147.A.110 on records of instructors, examiners, and assessors, 147.A.115 on instructional equipment, 147.A.125 on records, 147.A.135 on examinations, 147.A.200 on the approved basic training course, and 147.A.300 onward on aircraft type and task training.

Common mistakes

The most common mistake is confusing the role of Part-147 and Part-66. Part-147 approves the training organisation and the training/examination system. Part-66 governs the licence, ratings, and privileges.

Another recurring error is underestimating examination integrity and record control. In a Part-147 approval, weak examination discipline is not a side issue. It goes to the core of the approval basis.
