Douglas/Basler Basler, Bt-67 Turbo 67

Twin Turboprop

The Douglas DC-3, first flown in 1935, revolutionized air transport and remains one of aviation's most enduring designs. Nearly nine decades after its debut, hundreds still fly commercially and in utility roles worldwide. The DC-3T variant represents a modern turboprop conversion, typically replacing the original Pratt & Whitney R-1830 radial piston engines with Pratt & Whitney Canada PT6A turboprops, dramatically improving reliability, fuel efficiency, and high-altitude performance while preserving the airframe's legendary ruggedness. These conversions extend the operational life of an aircraft that helped establish the economics of airline travel in the 1930s and served as the military C-47 Skytrain workhorse throughout World War II, dropping paratroopers over Normandy and supplying forces across every theater. The turboprop conversion transforms the DC-3's capabilities: PT6A engines deliver better single-engine performance, reduced maintenance, and the ability to burn readily available Jet-A fuel instead of scarce 100LL avgas. Cruise speeds remain modest at around 160-180 knots, but the type excels in short-field operations, unprepared strips, and harsh environments, precisely the missions that keep DC-3Ts flying in remote regions of Canada, Alaska, and developing nations. Maximum takeoff weight for most conversions hovers around 28,000 pounds, with typical payloads of 6,000-8,000 pounds depending on configuration. The aircraft's low stall speed, benign handling, and ability to operate from gravel and grass runways make it irreplaceable for cargo, skydiving, and specialty charter work where no modern replacement offers the same combination of capacity, durability, and operating economics on marginal airstrips. SkyMeter has tracked 88 flights across 13 airframes and 11 operators, with ALCI Aviation Ltd. the largest observed operator.
