Description
The 000-170000-21 is a genuine Textron Aviation skin leading edge wing tip assembly extend that forms the contoured metal covering over the airframe structure. It is applicable to the Baron Series B55, E55, 58 or G58 and King Air B200, B200T, B200C or B200CT. It carries an export classification of ECCN 9A991, weighs 1.58 pounds, and measures 25.6 (L) x 10.35 (W) x 5.3 (H) Inches.
Because the 000-170000-21 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.
Because the Beechcraft Baron 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. Using the factory part number preserves configuration control, so the airframe stays consistent with its approved type design and the work is straightforward to sign off at inspection.
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 Baron, introduced in 1961 as a twin-engine development of the Bonanza, carried Beechcraft's reputation for solid handling into a capable light twin.
