Most manufacturers have definite installation policies for their TSOd and IFR products. What are they?
In order to ensure proper installation and certification of specific panel-mounted products, most manufacturers require the dealer to personally install every new IFR or TSO’d product they sell. There are usually two exceptions to this dealer installation only policy. First, a dealer may sell the equipment for amateur built/kitplane customers provided that this equipment is sold as part of an entire panel, with all interfacing between systems and bench testing completed by the dealer. With simple systems, a complete harness is sufficient. Second, a distributor may sell equipment direct to another dealer. VFR equipmnet is usually exempt from this requirement.
