Douglas DC-3, N510NR, undergoing conversion to a Basler BT-67 turboprop on the north side of Oshkosh Airport in May 1989. The BT-67 conversion includes retrofitting the aircraft with new P&WC PT6A-67R turboprop engines, lengthening the fuselage (seen here underway), strengthening the airframe, upgrading the avionics, and modifying the leading edges and wingtips. This became the 12th BT-67. It was sold to the Guatemala Air Force in 1992. In January 1990, Basler Turbine Conversions opened a new 75,000 sq ft hangar at KOSH for BT-67 conversions.

This Convair 440 flew with JAT Yugoslav Airlines (as YU-ADK) before entering cargo service in the US with Wright Airlines, Key Airlines and Basler Airlines. Later re-registered N115BF.

This Convair 440 previously flew with Combs in the US and Linjeflyg in Sweden (as SE-CRM). It was photographed on the Basler ramp at Oshkosh in the company of Convair 440-58, N29KE, in May 1989.

This former USN C-47A, N96BF is undergoing conversion to a Basler BT-67 in a hangar on the north side of KOSH airport. The fuselage stretch or plug can be seen in primer green and the registration is hand written on the lower part of the nose. The aircraft was displayed at the 1992 Farnborough International Air Show. The aircraft was written off in a fatal crash near Lobito, Central African Republic on Dec. 15, 1994 while flying with SL Aviation Services as N96BF. Both pilots were killed.
