Conversiones Turbo Basler
A small Oshkosh workshop that builds no new aircraft at all: it strips Second World War Dakotas to the bone and sends them back out as turboprop BT-67s for polar science, firefighting and counter-insurgency.
Basler Turbo Conversions: the company and the aircraft that made its name
The plane that led D-Day
In 2015 a researcher contacted a workshop at Oshkosh, Wisconsin, about a tired Douglas C-47 sitting in its yard. The airframe had been bought to be cut apart and rebuilt as a turboprop. It turned out to be the aircraft that led the paratroop drop on D-Day, 6 June 1944, later flown over Market Garden, the Battle of the Bulge and the Rhine crossing, before passing through 16 civilian owners. The Commemorative Air Force bought it that summer and then paid the same workshop to restore it to wartime condition. Its engines ran again in December 2017.
Warren Basler’s idea
The workshop was Basler Turbo Conversions, founded by Warren Basler, an Oshkosh operator whose DC-3s flew mail. To meet the demands of a US Mail contract he replaced their piston engines with turbines, and the answer became a standard package: Pratt & Whitney Canada PT6A-67R turboprops on a rebuilt Douglas airframe. The design began with an airframe left half-finished by United States Aircraft, which Basler moved to Oshkosh and completed. By March 1989 eight airframes were in work at Van Nuys, California, and by February 1990 a purpose-built 75,000 sq ft line was open at Wittman Regional Airport.
Ninety per cent new
A BT-67 is not a re-engined Dakota so much as a new aircraft wearing an old data plate. The fuselage is lengthened by 40 inches, the wing leading edges and tips are reworked, the structure is strengthened and the cockpit modernised; the company says about 90 per cent of the aircraft is replaced, at roughly 50,000 man-hours per conversion. Production runs at about two a year. The 70th was in work in 2022. Customers range from the Colombian air force, which flies a gunship version at night, to Antarctic research programmes in Australia, Germany, China and the United States.
