SHIM- TAPERED SHIM SPAR

The 45-115091-3 is a genuine Textron Aviation shim tapered shim spar that forms part of the wing's primary load-carrying structure. It is applicable to the Bonanza 36, King Air 100, King Air 350 Fusion, King Air 350C FM-36 & On, King Air 350C Fusion, King Air 350i, King Air 360, King Air 360C, King Air B200, B200T, B200C or B200CT, and King Air B200GT, among other compatible variants. It carries an export classification of ECCN 9A991. Because the 45-115091-3 is an original-equipment (OEM) structural component from Textron Aviation, it is built to the airframe manufacturer's specification and matches the type design as documented. Fitting the genuine part preserves the wing or airframe's engineered strength and keeps installation and inspection records clean. Across the Beechcraft Bonanza and King Air fleet, correctly identified factory parts like this keep every airframe consistent and configuration-correct. Airframe structure of this kind is engineered to specific load paths; the correct part is what keeps those paths — and the aircraft's certified strength — unchanged. Beechcraft was founded in Wichita, Kansas in 1932 by Walter and Olive Ann Beech, and has been part of Textron Aviation since 2014, uniting with Cessna and Hawker. The Beechcraft Bonanza is widely regarded as holding the longest production run of any aircraft — from its 1947 debut until Textron announced in November 2025 that it would wind down Bonanza and Baron production as the order backlog clears.
