Design and development

Basler Turbo Conversions was founded in 1990 solely focused on converting existing C-47/DC-3 airframes into the BT-67.^[2] Basler configures each new build to the client's specifications. Industries served include cargo, military, cloudseeding, and scientific research.^[3][4] The conversion includes fitting the airframe with new Pratt & Whitney Canada PT6A-67R turboprop engines,^[5] lengthening the fuselage, strengthening the airframe, upgrading the avionics, and making modifications to the wing leading edges and wingtips.

Due to the higher fuel consumption of the turbine engines of the BT-67, compared to the original piston designs fitted to the standard DC-3, range on the standard fuel tank, with 45 minute reserve, is reduced from 1,160 to 950 nautical miles (2,150 to 1,760 km). Basler provides a long-range fuel tank which increases the aircraft range to 2,140 nmi (3,960 km).^[3]

Gunship version

The Basler BT-67 has a gunship version used by the Colombian Aerospace Force as of 2017^[update] for counterinsurgency operations.^[6][7] The Colombian gunships are equipped with a forward-looking infrared (FLIR) ball, enabling the aircraft to conduct effective nighttime missions.^[8][9]
