Change notice

Revision 6 provides updated guidance to reflect the transition from a Quality Management System (QMS) to a system of safety management (Safety Management System or SMS) focus, as reflected in rule 145.65. We have also corrected the AC reference to AC 100-1, Safety Management, made stylistic changes and fixed typos and other minor errors.

Throughout, we have substituted guidance on quality management with reference to AC100-1, as participants are advised to follow this AC when designing their SMS. Lastly, we have taken the opportunity to add a Version History.

We have also done a marked up version [PDF 712 KB] with the insertions highlighted in yellow and deletions in strikethrough so participants can check the changes easily.
