Interesting stuff-- I took my Microair 760 in to the Fresno FSDO, and talked to the avionics inspector and an airframe guy was right there with us. I asked him how to go about doing a field approval for it's installation and he asked my why I was going to use a 337 form. He stated that adding a radio is certainly not a major alteration to the airplane- in fact he said that you are not altering the airplane at all, but adding an accessory. So, no 337 form for my Microair 760 installation. jan z Fresno On Fri, 23 Mar 2001 16:47:13 -0800 Greg Bullough <[EMAIL PROTECTED]> writes: > ----[Please read http://ercoupers.com/disclaimer.htm before following > any advice in this forum.]---- > > >At the risk of starting WW3, what are the rules on fitting > replacement > >and new instruments?
