The EU-China Aviation Partnership Project (APP) held a fruitful workshop from 13 to 14 March, on the Operational Suitability Data (OSD) concept applied in Europe as well as the Aircraft Evaluation Group (AEG) process currently in place in China.

Over the course of two days, Chinese and European participants listened to presentations covering the regulatory basis and methodologies to demonstrate compliance related to OSD and AEG. EASA experts gave overviews of each of the five OSD constituents: flight crew data, cabin crew data, master minimum equipment list (MMEL), simulators data, as well as the relatively newer constituent of maintenance certifying staff data. Following each of the five regulatory presentations detailing with the requirements for these, European industry stakeholders presented their methodology of complying with them. Among the aspects reviewed were the certification basis for OSD, how OSD is integrated into the certification process, OSD evaluations and evaluation tests, difference levels in some of the OSD constituents, such as OSD Flight Crew, changes to OSD, manufacturers’ internal OSD processes, and cooperation with the regulators.


This activity was the first organised by the EU-China APP on this topic. Through questions and discussion following the presentations, mutual understanding of the systems and process requirements were enhanced, especially pointing out similarities between the Chinese and European approaches to ensure that the necessary data for the safe operation of aircraft is made available.


Sixty-three participants attended the workshop, representing among others EASA, the CAAC Flight Standard Department and its Aircraft Evaluation Division, the AEG Offices of different regional Airworthiness Certification Centers of CAAC, the AEG Office of the CAAC China Academy of Civil Aviation Science and Technology, Dassault Aviation, Airbus, ATR, Leonardo Helicopters and various other European and Chinese companies.
