    Due to much Northern flying in the future and the shortage of 100LL fuel North Of 60 we are thinking of a Riley Conversion 421B, does anyone have experience with this aircraft/operating costs/handling/ maint costs/icy runway handling? Thanks in advance!Larry Loretto.

      I have flown half of the converted airplanes. What is the N number?
      Hard to beat the performance. A little mechanic training and the airplane is very economical for a turboprop.

      Thanks for your response, the aircraft is listed as 59Nm on the Globall Air web site, am also trying to find out if it is certified in Canada, {Our Feds are a strange lot!} We have a few years maintaining 421 aircraft so other than the engines we have everything in place to look after the airframe, any info would be welcome, Thanks, RG {Larry} Loretto.

        Larry,

        Yes. I have flown that airplane when it was in Oregon.
        E-mail me if you would like.

        We just purchased the Riley STC and are back into production in doing this turboprop mod. Contact me if you want info.

          Which STC did you purchase the P&W or Lycoming modification? Are you going to use new engines?

          The PWC PT-6-135A installation, new engines with a host of other upgrades including glass panel, paint, interior, winglets, VGs, extra fuel.

          Do you have a website or can you provide more details on performance and cost? Is there an engine/fuel only route? How does it compare to the Conquest?

          The Lycoming has a 600 hour hot section, which can be very expensive.

          We are working on the marketing details. It will be a 300+ kt airplane so compared to the 425 it will be much faster. We are not reinventing the wheel. Just fine tuning what has already been proven with the existing STC. We will do a customers airplane to whatever requirements they desire. Example, engine only, + whatever options they want. Right now we are spending a lot of dollars on getting the engineering cleaned up and new tooling and kits to do the installation. We will build a demonstrator and start rolling out the program later this year.

          Thanks, maybe there could be a durable thread for providing updates too? An upgrade path to competitive high performance turbines increases the value and lifetime of the entire fleet. Are you also looking at the 340 and 414?

            Is the Riley conversion only for straight leg 421s?

            #96496

            The Riley conversion is only for the “C” model. We will look at the 414 and the 421A and B after we start conversion on the 421C. Right now the only turbine for the 340 is the Silver Eagle 340 mod with the Rolls Allison turbine.

            #96505

            One problem on using the B models for a turboprop is the lower PSID. Higher cabin altitudes means you fly lower which hurts turbo prop efficiency.

            #96510

            So what is the verdict on the silver eagle 340 now it has been certified?
