Pace, "friend" may have misconstrued the TSA threat that every aircraft fitted for six pax or more (I think) will have to submit passenger manifests, crew criminal background/security checks etc before every flight.
Not sure if it's six pax, or six seats - would need to look again. AOPA USA onto it in a big way.
Could be that a Seneca would require passenger manifests and security cards etc. for every flight, yes.
