Non-mandatory Modification Embodiment Policy

Non-mandatory modifications will normally take the form of manufacturer’s Service Bulletins, or will be derived from them. Any other modifications (i.e. those not covered by a manufacturer’s Bulletin) will be initiated by AC Aviation in consultation with a DCA Approved Design Organization.

Modification & Approval Modification

For all modifications other than those introduced by manufacturer’s SB’s i.e. those proposed by AC Aviation or the contracted technical services organization for operational advantage or other reasons then these will be subject to the current FAA/EASA and DCA modification procedures to ascertain whether or not a modification is deemed to be classified as ‘Major’ or ‘Minor’.

The Director of Operation will agree all modifications before submission to the DCA. The appropriate contracted DCA Approved Design Organization with AC Aviation’s Maintenance Manager will be responsible for raising and submitting the Modification to the DCA for approval.

The Submission will include all of the necessary supporting documentation including drawings, proposed Flight Manual/Operations manual amendments, Weight & Balance Manual, supplements etc., as appropriate to the Minor Modification application. DCA approval will retained by AC Aviation’s Engineering and Planning
