It is technically airworthy. It gets run and worked on periodically. I have seen it fly. It belongs to the Friedkin family. They are the founders of PSA.
When you say 'technically airworthy', do they keep it in annual? I walked around it the other day and the airframe generally looks airworthy, although both wheel wells had quite an infestation of spiders possibly other critters.
Was it always a PSA plane? I thought it was interesting that it had the 'paddle' props that you usually only see on C-47s.
Any idea when it last flew?
