This article is from the Model Rockets FAQ, by Wolfram von Kiparski with numerous contributions by others.
There are two organizations which may certify you to purchase and use
high power rocket motors. These are the National Association of
Rocketry and the Tripoli Rocketry Association. Note that you must be
a member of the organization to certify for high power with that
organization. Once certified, both organizations recognize the
certification of the other, but this may change in the future.
As of April, 1996, new NAR certification procedures have gone into
Current NAR procedures:
- For Level 1 certification (the first step) one must fly an H or I powered
rocket successfully, and have it witnessed by two senior NAR members, one
of which must be high power certified. Fill out the proper form, have it
signed by the witnesses, and send it in to NAR HQ.
NOTE: NFPA 1127 allows an uncertified individual to purchase a single H
or I motor for certification purposes.
- For Level 2 certification (the next step up) one must take and pass a
written exam, and then successfully fly a J/K/L powered rocket.
Questions for the examination come from a pool of questions that are
available for review prior to taking the test.
- The NAR does not currently certify to Level 3 (M and up).
Tripoli certification procedures are scheduled to change on 1 Sep 1996.
At that time there will be three (3) high power certification levels:
- Level 1, allowing single motor H and I flights. No clusters or staging.
- Level II, allowing up through L motors, staging, clustering and hybrids.
- Level III, unlimited, allowing M power and up.
A written test will be required for Level II certification, in addition to
the certification flight. Level III certification requirements will require
pre-flight approval and review from the Tripoli Advisory Board.
