The Basler BT-67 is a utility aircraft produced by Basler Turbo Conversions of Oshkosh, Wisconsin. It is a remanufactured and modified Douglas C-47 (DC-3); the modifications are designed to significantly extend the DC-3's serviceable lifetime.

Design and development

Basler Turbo Conversions was founded in 1990 solely focused on converting existing C-47 airframes into the BT-67.^[1] Basler custom configures each new build to the client's specifications. Industries served include cargo, military, cloudseeding, scientific research, and various other applications.^[3]^[4] The conversion includes fitting the airframe with new Pratt & Whitney Canada PT6A-67R turboprop engines, lengthening the fuselage, strengthening the airframe, upgrading the avionics, and making modifications to the wing leading edges and wingtips.^[5]

Due to the slightly 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].^[6] The Colombian gunships are equipped with a forward-looking infrared (FLIR) ball, enabling the aircraft to conduct effective nighttime missions.^[7]
