Instructions for continued airworthiness [ICA] amendment (NPA 2018-01).
The objective of this Notice of Proposed Amendment (NPA) is to mitigate the risks linked to the uncertainty of the status of instructions for continued airworthiness (ICA) and therefore to avoid there being too much room for interpretation in the rules and standards, leading to differences and possible safety risks .
This NPA proposes to amend Annex I (Part 21) of Regulation (EU) No 748/2012 to clarify that ICA are part of the type certificate (TC), and to develop the related acceptable means of compliance (AMC) and guidance material (GM). It also merges the requirements related to record keeping, manuals and ICA in the various subparts into a single requirement for each of these aspects in Subpart A (new points 21.A.5, 6 and 7).
The proposed changes are expected to improve the harmonisation of ICA among the design approval holders (DAHs) in relation to the identification, approval, formatting and availability of ICA to the end users.
