This Notice of Proposed Amendment (NPA) addresses the safety risks identified for helicopter operations to offshore locations. The specific objective is to mitigate these risks by: assessing which CAT IRs need to be amended and complemented taking into account the situation in the Member States as well as the results of conducted studies; assessing if all offshore-related provisions should be included in a new subpart of Part-SPA, thus becoming a specific approval; assessing the risk and mitigating measures for non-commercial and specialised operations and, as appropriate, propose appropriate requirements; assessing whether new technology, either available or in use by some Member States, should be considered as a regulatory requirement. This NPA proposes to ask for the introduction of a specific approval for all helicopter offshore operations as a new subpart to Annex V (Part-SPA) to Commission Regulation (EU) No 965/2012. The proposed changes are expected to maintain the current high safety level of the operations achieved by the Member States where most of the offshore operations take place. Proportionality and level playing field for helicopter offshore operations are ensured by appropriate safety measures for the different types of operations. While CAT, NCC and SPO operators are required to follow the new Subpart SPA.HOFO, NCO operations are excluded from these operations.
