EASA Certification Specification CS-STAN – Considerations related to Certification Specifications for Standard Changes and Standard Repairs

Applicable up to and including ELA2 Aircraft

This Certification Specification (CS) is issued to identify standard changes which may be made to the aircraft without the need for further design certification requirements together with repairs which may be performed in conformity with FAA Advisory Circular AC 43.13-1B


Group Systems—Communication:

CS-SC001a — Installation of VHF voice communication equipment

CS-SC002a — Installation of a Mode S elementary surveillance equipment

CS-SC003a — Installation of Audio Selector Panels and Amplifiers

CS-SC004a — Installation of antennas

Group Systems — Electrical:

CS-SC031a — Exchange of conventional Anti-Collision Lights, Position Lights and Landing & Taxi lights by LED type lights

Group Systems — Avionics/NAV/Instruments:

CS-SC051a — Installation of ‘FLARM’ equipment

Note – FLARM (an acronym based on ‘flight alarm’) The system is also capable of being used to alert pilots to obstacle proximity subject to use of a suitable database. FLARM does not transmit any signal detectable by ACAS or ADS-B. This means that small aircraft which rely exclusively on FLARM for collision avoidance will be invisible to aircraft which rely on ACAS as a safety net against mid air collision.

Group Flight:

CS-SC251a — Installation of an Angle of Attack (AoA) indicator system CS-STAN

Group Miscellaneous:

CS-SC401a — Exchange of basic flight instruments

CS-SC402a — Installation of sailplane equipment
