2.       time-controlled components, including the life accumulated by the affected components in the applicable parameter, since the last accomplishment of scheduled maintenance, as specified in the AMP.

(e)     The owner or operator shall establish a system to keep the following documents and data in a form acceptable to the competent authority and for the periods specified below:

3.       data specific to certain components:

(i)      an in-service history record for each life-limited part based on which the current status of compliance with airworthiness limitations is determined;

(ii)     the CRS and detailed maintenance records for the last accomplishment of any scheduled maintenance and any subsequent unscheduled maintenance of all life-limited parts and time-controlled components until the scheduled maintenance has been superseded by another scheduled maintenance of equivalent scope and detail but covering a period not shorter than 36 months;

(iii)     the CRS and owner’s acceptance statement for any component that is fitted to an ELA2 aircraft without an EASA Form 1 in accordance with point 21.A.307(b)(2) of Annex I (Part 21) to Regulation (EU) No 748/2012 but covering a period not shorter than 36 months;

(iv)     the CRS and owner’s acceptance statement for any component that is fitted to an aircraft without an EASA Form 1 in accordance with point 21L.A.193(b)(2) of Annex Ib (Part 21 Light) to Regulation (EU) No 748/2012 but covering a period not shorter than 36 months.

4.       Record-keeping periods when the aircraft is permanently withdrawn from service:

(i)      the data required by point (b)(1) of point M.A.305 in respect of aircraft, engine(s), and propeller(s) which shall be retained for at least 12 months;

(ii)     the last effective status and reports as identified under points (c) and (d) of point M.A.305 which shall be retained for at least 12 months; and

(f)      The person or organisation responsible for the management of continuing airworthiness tasks pursuant to point M.A.201 shall comply with the requirements regarding the aircraft continuing airworthiness record system and present the records to the competent authority upon request.

(g)     All entries made in the aircraft continuing airworthiness record system shall be clear and accurate. When it is necessary to correct an entry, the correction shall be made in a manner that clearly shows the original entry.
