1.Changes in nominated persons. The competent authority should have adequate control over any changes to personnel specified in M.A.606(a) and (b). Such changes will require an amendment to the manual.

2.It is recommended that a simple manual status sheet is maintained which contains information on when an amendment was received by the competent authority and when it was approved.

3.The competent authority should define the minor amendments to the manual which may be incorporated through indirect approval. In this case a procedure should be stated in the amendment section of the maintenance organisation manual. Changes notified in accordance with M.A.617 are not considered minor. For all cases other than minor, the applicable part(s) of the EASA Form 6F should be used for the change.

4.The approved maintenance organisation should submit each manual amendment to the competent authority whether it be an amendment for competent authority approval or an indirectly approved amendment. Where the amendment requires competent authority approval, the competent authority when satisfied, should indicate its approval in writing. Where the amendment has been submitted under the indirect approval procedure the competent authority should acknowledge receipt in writing.
