You have to remember that once certified, it is legal. My Bellanca 1948
14-13-2 has only one belt for the back seat. I'd be willing to bet that a
new Viking has 4 seats with four belts and harnesses.

You have changed all the friction ends to metal to metal, haven't you?
Believe this was done by AD. They probably could make everyone have a
shoulder harness if they want to push it.

(b) Each forward-facing or aft-facing seat/restraint system in normal,
utility, or acrobatic category airplanes must consist of a seat, a
safety
belt, and a shoulder harness, with a metal-to-metal latching device,
that
are designed to provide the occupant protection provisions required in
§23.562.

Sounds like you need a safety belt for each seat and the word occupant
is
singular.

I don't know if the Pipers - which were certified with a single belt for
both occupants - were produced before, or after the change to "normal,
utility, or acrobatic category". I seem to remember flying a Taylorcraft
that had but a single belt, too - but I might be mistaken.
