NPA 2015-02

Systematic review and transposition of existing FAA TSO standards for parts and appliances into EASA ETSOs

This Notice of Proposed Amendment (NPA) addresses an economic and harmonisation issue related to the regular update of European Technical Standard Orders (ETSOs) due to new or updated and improved standards for parts and appliances.

More specifically, this NPA proposes the revision of CS-ETSO in order to:

(a) modify a number of ETSOs in order to harmonise them with the corresponding FAA TSOs;

(b) introduce new ETSOs (Index 1) which are, where possible, technically similar to existing FAA TSOs; and

(c) introduce a new ETSO (Index 2), not existing in the FAA TSO series (i.e. ETSO-2C515 Aircraft halocarbon Clean Agent — Handheld fire extinguisher).

The proposed changes are expected to reduce regulatory burden for validation of FAA TSO authorisations by EASA and vice versa, increase cost-effectiveness, and align CS-ETSO to the state of the art.
