1. Purpose
The maintenance organisation manual is the reference for all the work carried out by the approved maintenance organisation. It should contain all the means established by the organisation to ensure compliance with Part-M or Part-ML according to the extent of approval and the privileges granted to the organisation.
The maintenance organisation manual should define precisely the work that the approved maintenance organisation is authorised to carry out and the subcontracted work. It should detail the resources used by the organisation, its structure and its procedures.

4. Continuous compliance with Part-M and Part-ML
When a maintenance organisation manual no longer meets the requirements of this Part-M or Part‑ML, whether through a change in Part-M or Part-ML, a change in the organisation or its activities, or through an inadequacy shown to exist by verification inspections conducted under the organisational review, or any other reason that affects the manuals conformity to requirements, the approved maintenance organisation is responsible to prepare and have approved an amendment to its manual.
