• ED Decision 2022/011/R found in: Continuing Airworthiness (1321/2014) Part-M Part-145 Part-66 Part-147 Part-T Part-ML Part-CAMO Part-CAO (Jul 2024)

AMC1 145.A.50(d) Certification of maintenance ED Decision 2022/011/R The purpose of the certificate is to certify maintenance work carried out on assemblies/items/components/parts (hereafter referred to as ‘item(s)’). It also allows the removal from aircraft of items in a ‘serviceable’ condition in accordance with [AMC2 145.A.50(d)](#_DxCrossRefBm1518545028) in order to fit them to another aircraft/aircraft component. The certificate is to be used for export/import purposes, as well as for domestic purposes, and serves as an official certificate for items from the manufacturer/maintenance organisation to users. It can only be issued by organisations approved by the particular competent authority within the scope of the approval. The certificate may be used as a rotable tag by utilising the available space on the reverse side of the certificate for any additional information and dispatching the item with two copies of the certificate so that one copy may be eventually returned with the item to the maintenance organisation. The alternative solution is to use existing rotable tags and also supply a copy of the certificate. A certificate should not be issued for any item when it is known that the item is unserviceable except in the case of an item undergoing a series of maintenance processes at several maintenance organisations approved under [Part-145](#_DxCrossRefBm1518544883) and the item needs a certificate for the previous maintenance process carried out for the next maintenance organisation approved under [Part-145](#_DxCrossRefBm1518544883) to accept the item for subsequent maintenance processes. In such a case, a clear statement of limitation should be endorsed in Block 12. ##### AMC1 145.A.50(d) Certification of maintenance *ED Decision 2022/011/R* The purpose of the certificate is to certify maintenance work carried out on assemblies/items/components/parts (hereafter referred to as ‘item(s)’).
