This information, while meant to be encouraging, is far from it, IMHO.
Here we have a government agency that has heavily worked on and understood LSA rules for more than a decade. And multiple customer organizations out in the field providing input. And safety data in hand for years.
And yet, no decisions get made and no regulations get changed without an "N" year long process, where N is an integer between 2 and infinity.
Can anybody in FAA leadership make decisions? Do any of them understand the aircraft design field that they are supposed to be regulating?
In private industry an executive suite patting themselves on the back for making decisions they are paid to make, using a plodding 5+ year long process, would be kicked to the curb and rightly so.
If you say, "Well this lengthy collaborative process produces the best results", I remain unconvinced. No matter what regulations pop out at the end, there will always be groups unhappy with the results. In the end the decisions of where the rules stop and start are arbitrary and based on the opinions of hopefully knowledgeable regulators.
Keep the good parts of LSA rules, get rid of the bad.
Keep the current low stall speed, 2 pax, increase the max speed by 20 kt., increase gross Wt. to 2400 lb., invoke a rule to prevent spins via tip cuffs and vortex generators (as is well understood and used on ICON A5 and others). Provide a process to move trainer category aircraft in w/ mods, like C152's, Tomahawks, Skippers, 2 seat Warriors. This would be a reasonable extension of current LSA regs. Voila, a much more useable yet safe Light Sport category.
But mostly, get it done in this century.
