How Long Is A Repair Station Required To Keep Records

There has been a certain confusion about the understanding of "detailed maintenance records", because this term is used in a different context for continuing airworthiness direction and canonical maintenance organisation (AMO).

"Detailed maintenance records" as defined in M.A.614, 145.A.55(c) or CAO.A.xc(a) are required to be kept by an AMO (respectively Role-M/F arrangement, Function-145 organisation or CAO with maintenance privileges). Maintenance organisations are required to retain all detailed records in order to be able to demonstrate that they maintained aircraft and components in compliance with applicative requirements (come across as well remark).

"Detailed maintenance records" equally defined in One thousand.A.305(due east)(2) or ML.A.305(h)(1) are those records, coming from the AMO1 having performed maintenance, required to be kept by the possessor/operator (or the CAMO or CAO with Continuing airworthiness management privileges when required by Chiliad.A.201 or ML.A.201) assuasive to determine the aircraft configuration, the airworthiness status of the aircraft and all components installed, too as to plan time to come maintenance as required by the AMP, based on the last accomplishment.

Consequently, the AMO should transmit to the possessor/operator/CA(M)O a sure subset of the AMO maintenance records, including the certificates of release to service and repair/modification data related to the performed maintenance, so that the possessor/operator/CA(M)O can demonstrate compliance with M.A.305 or ML.A.305.

Non all AMO maintenance records need to exist transferred from the AMO to the owner/operator unless they specifically incorporate information relevant to aircraft configuration/condition and future maintenance. Thus, incoming certificates of conformity, batch number references and individual task card sign-offs verified by and/or generated by the maintenance organisation are not required to be transferred to the owner/operator/CA(G)O. However, dimensional information contained in the task carte sign-offs or work packages may need to exist transferred and kept by the possessor/ operator.

Information technology is to exist noted that the record-memory period requirements are slightly different for the AMO and the CAMO and CAO with Standing airworthiness management privileges. The AMO shall retain the records for iii years, whereas the CAMO and CAO with Continuing airworthiness management privileges has to retain their records until they are superseded by new data (equivalent in scope and detail), simply not less than iii years. The starting point in both cases is when the aircraft or component maintenance has been released.

Remark: It is considered a best exercise as part of the AMO record-keeping organization, (and it is also required by certain competent authorities) to record data (eastward.g. batch number or other tracking reference) relevant to the identification of all standard parts and cloth used during whatsoever maintenance. This exercise may limit condom and industrial risks in the case where a batch is recalled by the manufacturer. Such record does not demand to be transmitted to the owner/operator/CAMO/CAO with Continuing airworthiness management privileges.

FAQ Technical Records
*: Transmitted records is a subset of AMO maintenance records provided to the CA(M)O. Certain transmitted records do non need to be kept as a record by the CA(1000)O such as EASA Grade i for a component with no scheduled maintenance task selected and not subject to AD or modification/repair.
