A 1977 Beechcraft Baron 58TC turboprop project has been spotted for sale.
According to the listing, the aircraft began as a 1977 Beechcraft Baron 58TC (S/N TK46) with 1,531 hours total time and no damage history, later converted into an experimental single‑engine turbine “Czechmate” (N1NF) after being acquired via lien auction in 1989 with full FAA chain of title. The build replaces the twin piston configuration with a 750 HP Walter M601D turboprop, incorporating extensive structural modifications inspired by Beech’s factory Lightning prototypes, including a custom engine mount, reinforced nose structure, and high-quality carbon fiber cowling with advanced induction and cooling systems. The airframe retains the strengthened 58TC features (6200 lb gross weight, extended fuel capacity, heavy-duty landing gear, and corrosion-proofed structure) and includes a 5-blade reversible prop, deice systems, air conditioning, KFC200 autopilot, and complete interior. The project is largely complete with major fabrication finished, but requires engine overhaul, fuel cells, paint, avionics, and final assembly, and is offered with molds, tooling, spare parts, and documentation as a high-performance turbine conversion project capable of 250+ knot cruise.
The aircraft is located in Hastings, Florida and is currently available for US $169,000. Click here to check out the eBay listing, which includes many additional photos and details.
