attached is the 337 for 1252 installed in AK and i see nothing on gross weight
Also attached is the copy of 337 for 1478 which also doesn't specify a gross weight at all
if you actually need an original FAA copy you can order the original FAA file from The FAA. The files used to cost 10 bucks for each aircraft, these files that I am posting here have a little bit of information cropped off the margins but I do have the original
My files are about 10 years out of date but the only thing you will get if you order the files is what I have plus the bits and pieces put in the file over the last 10 yrs
I don't believe the 2 other 337's would be of any help in fact they would emphasize the lower gross.
