Two general-aviation aircraft designs, the Turbine Mallard and the all-metal tandem SAM LSA, are up for sale. Thierry Zibi said he enjoyed designing and building the SAM, but doesnt want to run a production company. The SAM is certified in Canada as an Advanced Ultralight, and is compliant with the LSA rule in the USA. Frakes Aviation acquired classic Grumman Mallards type certificate some years ago, and upgraded the fleet with turbine engines. The TC is back on the market now, as the current owners are ready to retire. Were looking for someone to take on the entire project, said Sam Jantzen, of Mallard Aircraft, who is working with Frakes. That would include not just the type certificate but the inventory of parts and several partially-built aircraft now owned by Frakes and based in Texas.
