AMENDMENT OF THE ARC Several practices have been adopted by competent authorities to amend ARCs, with a common one being to manually cross out the former registration and write in the new one. Although this practice is widely used, it may raise concerns regarding the validity of the certificate when reviewed by third- country entities, such as during ramp inspections. Moreover, this practice may not be suitable for electronically issued ARCs and could lead to several issues, including: — increased risk of human error, including irreversible mistakes in the certificate; — practical complications when the ARC needs to be amended multiple times due to frequent registration changes. Notwithstanding these limitations, competent authorities may continue to use this method. However, as a means of addressing the aspects described above, the following alternative approach may be considered when amending ARCs:
(a)issuing a new ARC (EASA Form 15a), completed with:
(1)information from the new competent authority;
(2)the new aircraft registration;
(3)the new ARC reference;
(4)all other information from the former ARC is copied into the new one, except for the fields labelled ‘Signed’ and ‘Authorisation No’; in the ‘Signed’ field(s), which are completed in the original ARC, the following statement should be added: ‘This ARC amends: [former ARC reference] on [date of amendment] by [signature].’ The corresponding ‘Authorisation No’, if applicable, should reflect the number of the person that makes the amendment.
(b)The new ARC should always be accompanied by the original ARC.
(c)For cases in which an aircraft undergoes multiple registration changes during the validity of its ARC, only the information in the most recent amendment is used to issue the new ARC. In such cases, the applicant must submit the original ARC along with all subsequent amendments to the new competent authority.
(d)The competent authority amending the ARC keeps a copy of both the former and the new ARC issued for traceability reasons.
(e)Subsequent extensions of the ARC are recorded in the most recent amendment.
