145.A.70 Maintenance organisation exposition (MOE)

(a)Personnel should be familiar with those parts of the MOE that are relevant to their tasks.

(b)The organisation should designate the person responsible for monitoring and amending the MOE, including associated procedures or manuals, in accordance with point 145.A.70(c).

(c)The organisation may use electronic data processing (EDP) for the publication of the MOE. Attention should be paid to the compatibility of the EDP systems with the necessary dissemination, both internally and externally, of the MOE.

(d)When information is provided by reference (e.g. separate document, manual or electronic data file), the organisation should establish clear cross-reference to such documents or files in the MOE and have procedures for the management of these document or files.

1.The purpose of the MOE is to: specify the scope of work and show how the organisation intends to comply with this Annex; and provide all the necessary information and procedures for the personnel of the organisation to perform their duties.

2.Complying with its contents will ensure that the organisation remains in compliance with Part-145 and, as applicable, Part-M and/or Part-ML.

This AMC provides an outline of the layout of an acceptable MOE. Where an organisation uses a different format, for example, to allow the exposition to serve for more than one approval within the scope of Regulation (EU) 2018/1139, then the exposition should contain an index that shows where the subject matter can be found in the exposition.
