Who can submit a Declaration of Continued Airworthiness or an application for the issuance of NARCs

In general terms, a Declaration of Continued Airworthiness or an application for the issuance of a NARC may be submitted by the owner of the aircraft. In the case of multiple owners, this may be done by any one of them.

In the specific case of ULM aircraft, in accordance with the provisions of article 34 of RD 141/2025, these tasks must be carried out by the person responsible for the maintenance and preservation of the airworthiness of the aircraft. This figure may be the owner of the aircraft or, in the case of leasing the aircraft or allowing another person to operate it, the lessee or the operator of the aircraft, provided that these are included in the aircraft Registration Certificate or the transfer of responsibilities for the maintenance of the airworthiness is included in the lease contract or any other title allowing the operation of the aircraft to another person (company deed, power of attorney, etc.), electronic apodera , the owner of the property must be given a written document signed by both parties stating that he/she has the capacity to act on behalf of the owner).

If the person responsible for the maintenance and preservation of the airworthiness of the aircraft is not the owner of the aircraft, in order to submit a Declaration of Continued Airworthiness or an application for the issuance of a NARC, it is first necessary to be registered in the “Portal de alta, modificación y gestión de contactos de Administrados SIPA”/"Portal for registering, modifying and managing SIPA Administrator contacts" as the owner's legal representative, attaching evidence of the owner's representation.
