CS-ETSO Amendment 16
This Decision introduces amendments to CS-ETSO taking into account the principles of efficiency and harmonisation.
It introduces into CS-ETSO new, updated and improved standards for parts and appliances, as follows:
- a number of European Technical Standard Orders (ETSOs) have been modified in order to harmonise them with the corresponding FAA TSOs;
- one new ETSO (Index 1) has been introduced, which is, where possible, technically similar to the existing Federal Aviation Administration (FAA) Technical Standard Order (TSO); and
- some new ETSOs (Index 2) have been introduced, which either do not exist in the FAA TSO series, or which contain significant technical differences from the corresponding FAA TSOs.
These amendments are expected to reduce the regulatory burden for the validation of FAA TSO authorisations by the European Union Aviation Safety Agency (EASA) and vice versa, to increase cost-effectiveness of compliance demonstrations and to reflect in CS-ETSO the technical state of the art.
