Here are some photos I took of Beechcraft AT-11 Kansan examples on display at Pima and the NMoUSAF. This is a military variant of the Beech Model 18, the civilian Twin Beech that was the basis for AT-7 Navigator, AT-11 Kansan and the C-45 Expeditor. The Heritage Flight Museum was replacing the complete wing spar when I saw it in May 2023.
