The Commission is to adopt the necessary implementing rules for establishing the conditions for the safe operation of sailplanes in accordance with Regulation (EU) 2018/1139, where such aircraft meet the conditions specified in points (b)(i) and (ii) of Article 2(1) of that Regulation.

As regards oversight of persons and organisations, the requirements laid down in Article 3 of Regulation (EU) No 965/2012 and Annex II to that Regulation should continue to apply with respect to air operations with sailplanes.

In the interest of safety and with a view to ensuring compliance with the essential requirements laid down in Annex V to Regulation (EU) 2018/1139, all operators of sailplanes covered by this Regulation, with the exception of design or production organisations performing certain operations, should be subject to a set of basic requirements.

Taking into account the less complex nature and smaller scale of commercial operations with sailplanes as compared to other forms of commercial aviation and following a risk-based approach, it is appropriate for commercial operations with sailplanes to only require a prior declaration to the competent authority, as set out in point (a) of Article 30(1) of Regulation (EU) 2018/1139. This Regulation lays down the detailed rules for making such declarations.

Considering the specific nature of certain operations and following a risk-based approach it is appropriate to exempt certain operations with sailplanes from the requirement of a prior declaration.

In order to ensure a smooth transition and to give all parties concerned sufficient time to prepare for the application of that new regime, this Regulation should only apply six months after entry into force.

The measures provided for in this Regulation are in accordance with the opinion of the Committee established by Article 127 of Regulation (EU) 2018/1139,
