Change notice

Revision 4 of this AC:

Revision 5 of this AC adds a section in Subpart C, Aircraft Maintenance Engineer Ratings Rule 66.103(3), Foreign B1 Training Courses (Limited powerplant platform ratings). This explains the process which enables acceptance of foreign B1 courses to allow for a limited powerplant rating to be awarded when fitted to the specified airframe platform. It deletes the section Transitional Arrangements, makes stylistic changes to align with current AC format and fixes minor errors.
