14 Approval of certain maintenance data
       14.1Subject to paragraph 14.2 and for subregulation 2A (4) of CAR, instructions are approved for paragraph 2A (2) (e) of CAR if the instructions are:
(a) about how maintenance on an aircraft, an aircraft component or aircraft material is to be carried out; and
(b) in an advisory document, as it exists from time to time:
           (i) compliance with which is not required by law; and
           (ii) published by CASA, the European Aviation Safety Agency, or the NAA of a recognised country.
Note   The approval under this paragraph of certain instructions in a relevant document as maintenance data under paragraph 2A (2) (e) of CAR does not constitute approval of a modification or repair for the purposes of regulation 42U of CAR. The approval under this paragraph only provides for the instructions in the relevant documents to be used to supplement the information in an approved modification or repair in relation to how that modification or repair may be carried out.
       14.2The approval under paragraph 14.1 of the instructions in a document is subject to the condition that the instructions may only be used if:
(a) the maintenance data mentioned in paragraph 2A (2) (a), (b), (c) or (d) of CAR for the aircraft, aircraft component or aircraft material does not provide sufficient detail on how the maintenance is to be carried out; and
(b) the person carrying out the maintenance on the aircraft, aircraft component or aircraft material first determines that the instructions are:
 (i) appropriate to the aircraft, aircraft component or aircraft material to be maintained; and
 (ii) directly applicable to the maintenance that is to be carried out;
