Basler Turbo Conversions was founded in 1990 solely to convert existing C-47 and DC-3 airframes into BT-67s. Basler configures each conversion to a client's specifications. Industries served include cargo, military, cloudseeding, and scientific research. 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 wings'
leading edges and
wingtips.

Basler provides a long-range fuel tank which increases the aircraft range to . The Colombian gunships are equipped with a
forward-looking infrared (FLIR) ball, enabling the aircraft to conduct effective nighttime missions. ==Operators==
