Acceptance of ETSOA/TSO
All new applications for validation of FAA TSOs received by EASA shall be dealt with as per the FAA-EASA Technical Implementation Procedure (TIP) rev. 5, paragraph 2.5 , as from 02 March 2016.
As of this date, EASA accepts applications for validation only for the following TSO articles that are not covered by reciprocal acceptance, as per TIP FAA-EASA rev. 5 subparagraph 2.5.2:
- TSO/ETSO-C90 articles containing active components (ref. FAA Order 8150.4)
- TSO-C153/ETSO-2C153 integrated modular avionics
- TSO-C23 single harness emergency parachutes and all ETSO-C23 parachute equipment
- TSO-C77/CS-APU auxiliary power units
EASA will not accept applications from USA for revisions to existing ETSO certificates for all articles.
Minor changes to TSOAs where a validated ETSOA exists are processed by the FAA and will be accepted as per the provisions of the TIP. Therefore the existing ETSOA certificates will not be revised.
