PAI 700 Vertical card compass FAA form 337
Herb.
The TSO is just the document for the part to be allowed to be installed into an airplane. BUT it doesn't approve for the actual install, ie, Form 337 approved data. I ran into this problem on my C172 when I installed a TSO'd electric tach, the local FSDO would not allow the install without approved documentation, ie, Field approval through a designated maintenance engineer. Or a Form 337.
