FAQ n.121049

A Base Maintenance activity on aircraft registered in an EASA Member State started in my organisation under the UK CAA Part-145 approval before December 31, 2020 and will be completed after January 1, 2021. Is it possible for my organisation to issue a Certificate of Release to Service (CRS), after January 1, 2021, under the Part-145 approval issued by EASA?


Yes, it is possible. A CRS is to be issued under your UK CAA Part-145 approval for all the activity performed until December 31, 2020, according to 145.A.50(c) and (e). Based on those provisions, it is possible to release the maintenance performed, as long as the incomplete maintenance is properly identified. All the remaining activity from January 1, 2021, will be performed under your new EASA Part-145 approval, including the possibility to issue the final CRS, provided all EASA Part-145 requirements have been met during the maintenance.  The same principle is also applicable for any maintenance under Cx/D1/Bx ratings.
