Line Up and Wait
I am working through the installation drawings for a Sandel 3500 in a Socata TB20GT.
The only STC is for a Cessna 421C.
Sandel say that an AFMS is mandatory for the 3500 (understandable).
What is not clear is whether there is the slightest chance of doing this as a Minor Alteration.
One can install a Garmin 430W (e.g.) in that way, but that comes with an AML STC.
There is a document floating around which lists the 3500 and implies it is a Major Alteration. I also see an extract from it in the back of the 3500 installation manual.
However, one contact I have in the US certification scene informs me that that document was cancelled and no longer applies. He has no more details - at least not until I throw some money at this.
If it has to be a Major Alteration then my only option is the DER/8110-3/337 route because the NY IFO is no longer processing 337s for US registered aircraft outside the USA.
