I had to check it out.
Detailed Summary: Basler BT-67 (Douglas DC-3 Turbine Conversion)
The video provides an overview of the Basler BT-67, a heavily modernized turboprop conversion of the legendary Douglas DC-3/C-47. Often called the “Douglas DC-3 Turbine,” it extends the life of one of aviation’s most iconic and durable aircraft into the modern era.
Historical Context
The DC-3 revolutionized commercial air travel and military transport in the 1930s and 1940s. While larger, faster airliners eventually replaced it on mainline routes, many DC-3s continued flying with smaller operators worldwide due to their ruggedness and short-field performance. By the 1980s, Warren Basler recognized the potential for a thorough upgrade, leading to the founding of Basler Turbo Conversions Inc. in 1990 in Oshkosh, Wisconsin.
The Conversion Process
Basler takes original DC-3/C-47 airframes and essentially rebuilds them from the ground up over thousands of man-hours. Key modifications include:
- Wings: New wingtips and modified leading-edge sections for improved aerodynamics (replacing the classic curved DC-3 wingtips).
- Fuselage: A stretch forward of the wings, increasing interior volume significantly — from 905 cubic feet on a standard DC-3 to 1,225 cubic feet on the BT-67.
- Engines: Replacement of the original piston radial engines with two modern Pratt & Whitney Canada PT6A-67R turboprop engines. These are five-bladed powerplants similar to those used on the Beechcraft 1900 and Shorts 360.
- Systems: Complete overhaul of electrical and hydraulic systems, plus a fully updated flight deck with modern avionics.
- Structural: The airframe is strategically strengthened and engineered to achieve zero accumulated fatigue damage. After conversion, the aircraft is essentially a brand-new, zero-time airframe.
Performance and Capabilities
The BT-67 excels in demanding environments:
- Payload: Maximum payload of 14,000 lbs — an increase of nearly 5,000 lbs over the standard DC-3.
- Runway performance: Retains excellent short-field capability, operating from unprepared runways only a few thousand feet long.
- Operations on snow/ice: Can be equipped with wheel skis.
- Range: The PT6A engines burn more fuel than the originals, but optional long-range fuel tanks can double capacity from 772 gallons to 1,542 gallons.
Notable Operator
Ken Borek Air (based in Calgary) operates a fleet of nine BT-67s. The aircraft fly to remote locations in the Arctic and Antarctic, where their combination of ruggedness, payload, short-field performance, and ski capability is unmatched.
Overall Assessment
The video emphasizes that the BT-67 successfully modernizes the DC-3 while preserving its legendary strengths. As the saying goes, “the only replacement for a DC-3 is another DC-3” — and Basler has delivered exactly that, but better. The result is a rugged, reliable, turbine-powered aircraft expected to keep the DC-3 design flying well past its 100th birthday.
The presenter notes the BT-67’s popularity among viewers and positions it as a niche but highly capable aircraft that continues to prove its worth in challenging environments where newer designs often fall short.
