A couple of weeks ago, I contacted the FSDO in Miami about a CD model 
that had never been converted to a 1400 lb gross weight aircraft by 
virtue of a 337 but had an error in the weight and balance.  A month 
after manufacture, landing lights were added and the weight and 
balance were recalculated erroneously using 1400 lb gross weight.  
The operating limitations at the time of manufacture listed the gross 
weight at 1260 lbs, which should have been used for the calculations 
but was not.
The answer I got was this;  
"THERE ARE NO CERTIFICATED AIRCRAFT THAT ARE ELIGIBLE AS A LIGHT 
SPORT AIRCRAFT".  Caps intended.  Yikes!  
I asked if that meant Piper Cubs and Taylorcraft BC-12's also and 
they responded "That's what our expert says".
A further check by another person with the FSDO in Des Moines got the 
same answer.  
I think the guys at the FSDO are interpreting the phrase " A specific 
type of aircraft could not ever have been certified at a higher gross 
weight any time in its history" as meaning any airplane that had any 
versions that exceeded 1320 are not eligible as light sport aircraft. 
Oklahoma City says the FSDO's are responsible for final determination 
of light sport eligibility. I also think their is some "field 
guidance" from headquarters out there since we got the same response 
from two different FSDO's.
Point is, before we all go off half-cocked about the gross weight 
rule, we'd better make some subtle inquiries to be sure we are on the 
right track before we blow our foot off and have all Ercoupes 
declared as non-light sport.

PS  Still haven't found an instructor with his own plane to give me 
an hour of dual so I can get insurance.  Glen's plane is in the shop 
for a month. Mine is in Iowa. I am in Naples, FL. I have an ATP and 
not a learner's permit. Anybody got any ideas?
