EASA CS-25 is the European Union Aviation Safety Agency Certification Specification for Large Aeroplanes. This certification procedure applies to large, turbine-powered aircraft, with max take-off weight more than 5,700kg (CS 25.1). It describes the minimum requirements that must be met for the certification of an aircraft in this class.
The aircraft was EASA CS-LSA fully electric type certified in June 2020 and it is intended primarily for the training aircraft role, particularly multiple successive take-off and landings at the airfield.

EASA is responsible for new type certificates and other design-related airworthiness approvals for aircraft, engines, propellers and parts. EASA works with the EU member states' civil aviation authorities (CAAs) but has taken over many of their functions in the interest of aviation standardisation across the EU and in the non-EU member Turkey.

The corresponding EASA Acceptable Means of Compliance AMC 25.1309 (included as a section of CS-25) does recognize ARP4754/ED–79. The FAA and EASA have both subsequently recognized ARP4754/ED–79 as valid for certification of other aircraft categories, and for specific systems such as avionic databuses.
Apart from this annex, there are also several certification specifications, including CS-25, for large aircraft, and CS-23, for medium and small aircraft. In application, airworthiness standards include a probability of loss of aircraft (PLOA) that is designed to be controllable (PLOAdc) as an overall attribute. [5]
The first flight, originally scheduled for early 2008, was postponed due to delays and financial pressures. EADS announced in January 2008 that engine issues had been responsible for the delay.
