The objective of Decision 2020/010/R is to provide state-of-the-art means for showing compliance with the applicable requirements with regard to the following:

• reporting, analysis and follow-up of occurrences in civil aviation;
• certification of products and parts equipped with electronic control systems;
• certification of in-flight entertainment (IFE) systems;
• certification of airborne electronic hardware (AEH);
• management of open problem reports (OPRs).

These amendments to AMC-20 are expected to facilitate the certification and the occurrence-reporting processes. Overall, they would bring safety and economic benefits, and have neither environmental nor social impacts.

In addition, Decision 2020/010/R creates a consolidated index table showing all the AMC-20 guidance issued by EASA. This is expected to increase transparency and facilitate the application of those AMCs.

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.
