Title:  Beechcraft T-42A Cochise (Model 55 Baron)

The Model 55 Baron was developed from the earlier Model 95 Travel Air by replacing the tail unit (itself a T-34 component) with the swept tail unit from the Debonair, streamlining the engine nacelles and fitting six-cylinder engines, and giving the aircraft a new name. This was Beech’s response to the introduction of the Piper Aztec and the Cessna 310. The aircraft first flew in 1960 and has been in almost continuous production since.

Following and complementing the original model 55 came the model 56 which used more powerful engines and a higher weight. A model 58 followed using a lengthened fuselage, with turbocharged engines and a pressurised cabin options. The three main models were produced together along with different variants introducing more minor changes. The US Army took delivery of 65 examples of the B55 as an instrument trainer.
