Regular update of CS-ETSO

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:

  • modify a number of ETSOs in order to harmonise them with the corresponding FAA TSOs;
  • introduce one new ETSO (Index 1) which is, where possible, technically similar to the corresponding FAA TSO; and
  • introduce some new ETSOs (Index 2), which either do not exist in the FAA TSO series, or which contain significant technical differences from the corresponding FAA TSOs.

The proposed amendments are expected to extend the possibilities of ETSO authorisations for EU applicants 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.
