It is important to note that this is just the PROPOSED rulemaking to modify the Light Sport rule under MOSAIC and that the comment period for the new rule is currently open. Comments are read and the rule can be changed based on the comments. For instance, the maximum clean stall speed includes planes like the Cessna 172, but excludes the Piper Cherokee series aircraft, which miss by roughly 2 kts. If sufficient comments suggest raising it by a couple of knots to include the Cherokee line and all the Cardinal aircraft, there is a very good chance that could happen. Expect the actual rule to be announced at Oshkosh at the earliest next year. If it doesn't make it by then, I could take until late fall. But by all means, I would encourage all to comment to the FAA on the Mosaic NRPM. The comment period closes on October 23, 2023! Read the NRPM at <https://www.federalregister.gov/documents/2023/07/24/2023-14425/modernization-of-special-airworthiness-certification> and use the link at the top of that page to enter an official comment.
FWIW, all three of my planes (SuperCub, Marquart Charger Biplane, and RV-6) will qualify to be flown as Light Sport under the proposed rule. I am a happy camper, even though I don't have a need to fly under Light Sport Rules. -Jeff Scott Arkansas Ozarks > Sent: Thursday, August 31, 2023 at 9:04 PM > From: "Larry Flesner via KRnet" <krnet@list.krnet.org> > To: krnet@list.krnet.org > Cc: "Larry Flesner" <fles...@frontier.com> > Subject: Re: KRnet> rule changes > > > On 8/31/2023 7:58 PM, patr...@gmcmotorhome.com wrote: > > Note that the stall speed requirement is for "clean" stall speed.
