Introduction
Commission Delegated Regulation (EU) 2019/897 of 12 March 2019 - Inclusion of Risk-Based Compliance Verification in Annex I and the Implementation of Requirements for Environmental Protection
• In accordance with Article 83 of Regulation (EU) 2018/1139, the Agency itself, or through national aviation authorities or qualified entities, is to carry out investigations necessary for the performance of its certification tasks.
• The Agency assesses the applications but it is not required to carry out an exhaustive investigation in all cases pursuant to Article 83 of Regulation (EU) 2018/1139.
• Therefore, in order to better mitigate any safety risks due to selective investigations and to improve the effectiveness, transparency, and predictability of the certification process, certain selection criteria should be provided to allow determining which compliance demonstrations should be verified by the Agency and how exhaustively.
• Those criteria should be based on the safety oversight and management principles set out in Annex 19 to the Convention on International Civil Aviation (]‘the Chicago Convention’).
Furthermore, under Regulation (EU) No 748/2012 holders of design organization approvals are to take certain certification decisions, instead of the Agency.
• In line with their terms of approval and under the relevant procedures of the design assurance system.
• Based on the experience holders of design organization approvals should be entitled to certify certain major changes to type certificates and issue certain supplemental type certificates.
» In order to limit risks to aviation safety and having regard to environmental protection requirements, those new privileges should only relate to certification of major changes of a limited novelty and should be granted only to those holders who can correctly exercise those new privileges.
» The latter should be demonstrated through showing a satisfactory performance in previous similar major changes with the involvement of the Agency.
Air operators are to conduct check flights after maintenance to ensure the proper functioning of certain aircraft systems that cannot be verified on the ground.
• Accidents or serious incidents encountered in the past during those flights reveal that certain maintenance check flights should not be conducted under a certificate of airworthiness (or restricted certificate of airworthiness) but should require a permit to fly.
• Therefore, flying an aircraft for troubleshooting purposes or to check the functioning of one or more systems, parts, or appliances after maintenance
Operational Suitability Data (OSD)” means data, which are part of an aircraft type-certificate, restricted type-certificate or supplemental type-certificate, consisting of all of the following:
• The minimum syllabus of pilot type rating training, including determination of type rating;
• The definition of the scope of the aircraft validation source data to support the objective qualification of simulators or the provisional data to support their interim qualification;
• The minimum syllabus of maintenance certifying staff type rating training, including determination of type rating;
• Determination of type or variant for cabin crew and type-specific data for cabin crew;
