find it hard to believe that you can carry a DG designated Cargo A/C only with Pax
There has yet to be anything here that is restricted to Cargo Aircraft only (except by large volume and assuming John was talking about AVTUR @60lt max for pax a/c, not AVGAS @5lt max for pax a/c).
I can relate my own experiences to transporting m/cycles that where designated cargo A/C only due the fact it had carried fuel previously, and had to meet requirements for transport.
UN3166, Engines internal combustion, flammable liquid powered: Class 9 Misc label, Pax& Cargo: No limit, Pkg Inst 900. ERG 9L. If the motorbike was flammable gas powered
then it's CAO.
