Shockie:
go to the Nar certified motors list a the url mikeyd posted earlier. Once there simply scroll down the page instead of clicking on the "combined list" prompt.
It was my understanding the certified motors list is updated monthly? the date on this list is as of this morning Feb. 08, 2004
which still lists the A10-0T with the #3 notation.
To jump on my Soapbox a little:
It has been my personal contention the "de-certification" of motors for Sport flights is now and always has been WRONG. I and others are trying to get S&T to amend or drop this now proven outlandish practice. Once a motor is certified as safe.. how or more important Why would you pull that certification? Do old motors become unstable, dangerous or a threat to ourselves or others. The answer is a resounding NO! Several independant studies have shown the Old BP motors (many from the 1960's) performed within the manufacturers spec's when flown in 2002 4 decades later! The only "concern" was the clay caps seemed to become so hard over time they need to be scored slightly to allow the ejection charge to work properly.. I can tell you for a fact I personally fly ancient motors on a regular basis, without a single mishap or ill effect to model or person
Matt Steel and assicoates did an exhaustive study in 1997 or 98 which conclusively showed vintage BP model rocket motors performed as intended after 30 or more year, with minimum power lose. S&T should not be rescinding safety certifications which are stamped clearly on each motor, simply because they are old. De-certification for contest use is a completely different matter having more to do with availability than safety. To eliminate some scare motors from the competition field is fine to maintain a degree of leveling the playing field. Safety certification for general use once given should not be rescinded by the Nar until the motors are used or destroyed by the person who spent the money on them.
This dicscussion of a widely available, perfectly good booster motor is a perfect example of this Flawed practice. A10-0T's and many other discontinued motors out here are just fine to use. the old FSI F-100's may be an exception..but maybe not
End of editioial, I hope this isn't considered political.. it's mostly common sense
keep em flyin OLD and/or Micronized!
