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

Development

The design was based upon a single airframe that United States Aircraft had begun converting. After the company closed, the aircraft was moved to Oshkosh, where work was completed. It was then tested in Alaska and contracted to the U.S. Forest Service.

By March 1989, production of eight airframes had begun at a plant in Van Nuys, California. An additional production line opened in a purpose-built 75,000-square-foot (7,000 m²) facility on the east side of Wittman Regional Airport by February 1990. United Technologies, owner of the manufacturer of the PT6, became a distributor for the BT-67 that October. At the same time, it agreed to oversee a subcontractor performing conversion work using kits in Taiwan. Early in production, four airplanes were seized by the federal government as part of an investigation into drug trafficking, but released after Basler was cleared of any wrongdoing.

Design

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.

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 a 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).

Gunship version

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