R63 NAR S&T Clarification 23 Jul 2000

In response to member and manufacturer requests, the NAR Standards and Testing committee has examined the question of gluing something (such as a thrust ring) to the external surface of a rocket motor casing. We find that this does not modify the motor case and so long as it does not modify motor performance, this does not violate the NAR safety codes.

Note that NAR Contest Rules (the "Pink Book") may require further limitations for NAR Contest flights.
