AMC Acceptable means of compliance

## AMC 66.B.305(a) Conversion report for national qualifications

1\. Conversion reports prepared on the basis of point 66.A.70(c) should include a comparison between the scope of the national qualification (i.e., the national qualification requirements) and the scope of the Part-66 licence qualification (i.e., the Part-66 qualification requirements), which should be performed on the basis of a detailed analysis of the national and Part-66 basic qualification standards. The report should identify where a difference between the two standards exists and where such a difference would lead to a limitation on the Part-66 licence.

2\. Conversion reports prepared on the basis of point 66.A.70(d), which are limited to other-than-[complex motor-powered aircraft](https://avioverse.aero/glossary/easa/complex-motor-powered-aircraft) not used by air carriers licensed in accordance with Regulation (EC) No 1008/2008 should include the privileges associated to the national qualification. The reports should identify which limitations are needed to the Part-66 licence in order to maintain these privileges.

GM Guidance material

## GM 66.B.305(b) 3 Conversion report for national qualifications

As conversions performed on the basis of 66.A.70(d) are aimed to maintain the privileges of the pre-existing national qualification, the limitations introduced on the Part-66 licence are not linked to possible differences between the scope of the national qualification and the scope of the Part-66 licence qualification. This conversion does not include such comparison.

This means that, in order to remove such limitations, full compliance with the conditions of Part-66 needs to be demonstrated.
