Isn't that how most STCs work? The owner of the STC issues the STC
doc for a specific airplane by serial number. If I buy an STCed
product, it's only good for the serial number of the plane I purchased
it for. I've never heard of STC holders issuing new STC doc for
free, if you moved the product to another airplane. I'd think the
autogas STC folks would probably go broke if you could transfer the
STC without their permission.

Such an odd system. I would think that is safety were the primary
concern
it would work by precedent, i.e., once someone demonstrated that a
certain
installation of product X in aircraft type Y was safe and effective that
from that point on it would be up to the A&P and/or avionics tech to
make
sure the procedure was properly adhered to.


That would be fine if it wasn't so expensive to demonstrate to the FAA
that
it is a safe mod.


Yes, that's definitely a problem that occurred to me. I would hope that
there would be a way to reduce this cost by application of some common sense
for most mods but maybe I'm expecting too much. I still think the present
way of doing things is a strange way of financing STCs.
