STIFFENER

The 000-110010-21 is a genuine Textron Aviation stiffener — a formed reinforcing member that adds rigidity and helps distribute structural loads. It fits the Baron Series B55, E55, 58 or G58, Bonanza 36, Bonanza F33, G33, F33A or F33C, King Air 100, King Air C90, C90A, C90GT or E90, King Air C90GTi, and King Air C90GTx. It carries an export classification of ECCN 9A991. As an original-equipment (OEM) structural part supplied directly by Textron Aviation, the 000-110010-21 is manufactured to the aircraft maker's specification for material, dimensions, and finish, and cross-references the type design exactly as documented in the maintenance data. For a structural member, the genuine correctly identified part preserves the engineered load paths and keeps the airframe configuration-correct. Because the Beechcraft Baron, Bonanza, and King Air aircraft share extensive structure and hardware, a single part like this is often common across several variants. 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 Baron — a twin-engine member of Beechcraft's piston line introduced in 1961 — shares much of its structure and hardware with the Bonanza.
