REGULATORY AFFAIRS ------- Randall Clague
In a related item, NPRM #968, concerning the 62.5-gram limit on amateur solid-rocket grains, is now in a public comment period.
I can't take credit for this one; it's probably a Dave W find. ATF is proposing to settle the 62.5 gram controversy once and for all, by exempting only sngle use and reloads below that limit.
From the existing regulation, 27 CFR 55.141...
"Subpart H—Exemptions
"§ 55.141 Exemptions.
"(a) General. Except for the provisions of §§ 55.180 and 55.181 [plastic explosives -R], this part [all of part 55, which regulates commerce in explosives -R] does not apply to:"
...and from the NPRM, beginning at 68 FR 4406, but with the section we care about at 68 FR 4419...
"(7) The importation and distribution of—
"(v) Model rocket motors consisting of ammonium perchlorate composite propellant, black powder, or other similar low explosives; containing no more than 62.5 grams of total propellant weight and designed as single use motors or as reload kits capable of reloading no more than 62.5 grams of
propellant into a reusable motor casing."
Looks like they've settled the 62.5 gram reload issue by tying the weight limit to the motor, not to the reload.
I can't see this having any impact om ERPS, since almost everything we fly has more then 62.5 grams of propellant anyway.
