AMC1 145.A.30(j)(5)(i) Personnel requirements

CAA ORS9 Decision No. 38

In case it is necessary to issue a one-off certification authorisation to a certifying staff on an aircraft type for which he or she does not hold a type-rated authorisation, the following procedure is recommended:

1. The flight crew should communicate full details of the defect to the maintenance organisation. If necessary, the maintenance organisation will then request the use of a one-off authorisation from the compliance monitoring personnel.

2. When issuing a one-off authorisation, the compliance monitoring personnel should verify that:

(a) full technical details relating to the work required to be carried out have been established and passed on to the certifying staff;

(b) the organisation has an approved procedure in place for coordinating and controlling the total maintenance activity undertaken at the location under the authority of the one-off authorisation;

(c) the person to whom a one-off authorisation is issued has been provided with all the necessary information and guidance relating to maintenance data, and any special technical instructions associated with the specific task undertaken. A detailed step-by-step worksheet has been defined by the organisation, and has been communicated to the holder of the one-off authorisation;

(d) the person holds authorisations of equivalent levels and scopes on other aircraft types that have of similar technology, construction and systems.

3. The holder of the one-off authorisation should sign off the detailed step-by-step worksheet when completing the work steps. The completed tasks should be verified by visual examination and/or normal system operation upon return to an appropriately approved Part-145 maintenance facility.
