I have to take exception to the statement that Cessna's LSA entry is a sign that American made LSAs are coming. It turns out the Cessna plane is made in the Czech Republic and is powered by a Rotax engine made in Austria. So much for an American made LSA!

The only true American LSAs are the Zeniths and the Cub wannabes.

Fred,

You may be right that the FAA won't up the gross weight for LSA.  And,
you're right that we've been begging for an upgrade in the ultralight weight
limit for 25 years.  And the FAA has certainly rejected any increase in the
part 103 weight limit and they've rejected an increase again, recently.

There's pressure for them to up the LSA gross weight limit.  10,000 FBO/CFI
operations have Cessna 150 or 152 trainers they'd like to use for sport but
can't.  Since the number of Sport Pilots is barely 342 after almost two
years, the FAA is getting abuse for having created a failure.

(Though the FAA may well feel like SP is a total success because it's
bringing the BFI program to an end.)

But the second part of SP is to revitalize the production of aircraft.  So
far, it's partly a failure since almost all the SLSA aircraft are foreign
made.  But it's getting started here as exemplified by Cessna showing a
proof of concept SLSA aircraft at Airventure.  

If the LSA rules revitalize aircraft production, then there's pressure for
the FAA to not change the gross weight in a way that would include all those
used C-150/152s that can't provide any manufacturing jobs.

You mention that the weights chosen for the various new rules seem odd.
But, the weights do make sense.  Even though America did a Luddite, dumb
thing 30 years ago by not adopting the metric system, we have (sort of)
adopted the metric system.  The regulations are written with metric and
antique-British units.  The weights were chosen metrically.

115 kg ~= 254 lb.  or exactly 253.53 lb.

600 kg ~= 1330 lb. or exactly 1322.77 lb.

650 kg ~= 1430 lb. or exactly 1433.00 lb.

Since the rules explicitly include the metric measurements, you can make use
of the extra couple or three pounds if you need to.
