Certification Specifications and Guidance Material for maintenance certifying staff type rating training

The objective of this Notice of Proposed Amendment (NPA) is to improve the level of safety related to the minimum syllabus of maintenance certifying staff (MCS) type rating training (TRT), enabling design approval holders (DAHs) that comply with Annex I (Part 21) of Regulation (EU) No 748/2012 to identify the technical elements necessary to be addressed for the purpose of training of maintenance certifying staff involved in the maintenance of their products.

In addition, the intent is to ensure an adequate minimum syllabus standard at organisations that comply with Annex IV (Part-147) to Regulation (EU) No 1321/2014.

This NPA proposes:

  • the first issue of Certification Specification on MCS data (CS-MCSD) and the associated Guidance Material (GM);
  • the amending text for the GM to Part 21 applicable to Operational Suitability DATA (OSD)-MCSD that establishes guidance for the classification of changes to OSD-MCSD in accordance with Part 21.A. 

These proposals are expected to enhance safety and mitigate risk related to maintenance errors due to inadequate training and to establish a TRT minimum standard.
