The Commission is to adopt the necessary implementing rules for establishing the conditions for the safe operation of balloons in accordance with Regulation (EC) No 216/2008, where such aircraft meet the conditions specified in points (b) and (c) of Article 4(1) of that Regulation.

The specific rules for air operations with balloons should not extend, however, to the requirements in respect of oversight of air operations by the competent authorities of the Member States, as those requirements are not specific to any particular air operation activity but apply horizontally in respect of all such activities. As regards oversight, the requirements laid down in Article 3 of Regulation (EU) No 965/2012 and Annex II to that Regulation should therefore continue to apply also with respect to air operations with balloons.

In the interest of safety and with a view to ensuring compliance with the essential requirements laid down in Annex IV to Regulation (EC) No 216/2008, all operators of balloons covered by this Regulation, with the exception of design or production organisations performing certain operations, shall be subject to a set of basic requirements.

In order to provide additional protection for balloon passengers, provision should be made for certain additional requirements for operators engaged in commercial operations with balloons which should apply in addition to the basic requirements.

Those additional requirements should take account of the less complex nature of commercial operations with balloons as compared to other forms of commercial aviation, be proportionate and founded on a risk-based approach. Therefore, it is appropriate to replace the requirement of a certificate for commercial operations set out in Article 8(2) of Regulation (EC) No 216/2008 by a requirement to make a prior declaration to the competent authority and to lay down the detailed rules for making such declarations as well as certain other additional requirements.

However, considering the comparatively low level of complexity and in light of a risk-based approach, operators engaged in certain commercial operations with balloons should be exempted from the requirement of certification and from those additional requirements, including the requirement of making a prior declaration. They should instead only be subject to the basic requirements set out in this Regulation which apply to all air operations with balloons covered by this Regulation.

In order to ensure a smooth transition and to avoid as much as possible any disruptions when introducing the new, specific regime for balloon operations laid down in this Regulation, any certificates, authorisations and approvals issued to operators of balloons in accordance with the rules applicable prior to the date of application of this Regulation should continue to be valid and be deemed to constitute a declaration made in accordance with this Regulation for a limited time period. After the expiry of that time period, all operators engaged in commercial operations with balloons should make a declaration in accordance with the provisions of this Regulation.

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 from an appropriate later date.

The measures provided for in this Regulation are in accordance with the opinion of the Committee established by Article 65 of Regulation (EC) No 216/2008,
