Haven’t seen the Basler rebuilds but have read that DC3’s are being retrofitted with turbo props lately
Thats what Basler does, they rebuild the entire plan and have all the jigs and plans to fab replacement parts. From what I have seen the plane is essentially certified as new, and with the turbo props she can take off faster and carry more. They also do custom interiors and mods, really great when the bird rolls off the line and all FAA certified for everything they do
