Description
The 000-170000-121 is a genuine Textron Aviation skin structure assembly extend that forms the contoured metal covering over the airframe structure. It fits the King Air C90, C90A, C90GT or E90, King Air C90GTi, and King Air C90GTx. It carries an export classification of ECCN 9A991, weighs 1.56 pounds, and measures 25.55 (L) x 10.5 (W) x 4.75 (H) Inches.
Because the 000-170000-121 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 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. The factory part is built to the manufacturer's material and dimensional specification, so it installs as designed without the surprises a generic equivalent can bring.
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 King Air 90 series was the original King Air, first flown in 1964 and produced through 2021 — the line that established the type as the best-selling business turboprop in history.
