This Notice of Proposed Amendment (NPA) proposes to introduce new or updated standards for parts, taking into account the principles of efficiency and harmonisation.
In particular, this NPA proposes to:
- improve the existing wording in Subpart A and introduce a new reference to performing a design assurance level assessment of certain equipment;
- modify a number of ETSOs in order to harmonise them with the corresponding FAA TSOs;
- introduce some new ETSOs (Index 1) which are, to the extent possible, technically similar to the corresponding FAA TSOs; and
- introduce some new ETSOs (Index 2), which do not exist in the FAA TSO series.
The proposed amendments are expected to offer more possibilities for EU applicants to obtain ETSO authorisations and to align CS-ETSO with the state of the art and with European operational requirements.
These amendments will ensure a level playing field for European manufacturers and will increase the cost effectiveness of compliance demonstrations.
