A dual engine and prop swap on the turbocharged piston Cessna 310R could easily approach $200,000, with many months of downtime.
Don’t get me wrong—my wife and I have enjoyed our 1978 turbocharged Cessna 310R twin—powered by two Continental TSIO-520B engines. It’s been an outstanding family aircraft—fast, capable and a joy to fly. But there’s no denying the high-performance piston airplane landscape is changing. It’s becoming more challenging to find high-quality maintenance without dealing with long lead times, replacement engine costs are out of control and there’s grave uncertainty about the future of 100LL.
