Description
The 000-170013-31 is a genuine Textron Aviation rib assembly outboard — an internal structural member that helps define the airframe's shape and carry its loads. It is fitted to the 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 000-170013-31 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.
Parts like this are shared across the Beechcraft King Air aircraft, reflecting how much structure and hardware these models have in common.
Structural parts like this carry and transfer loads through the airframe, so exact form and fit are essential to preserving the design's strength and fatigue life. For a regulated aircraft component, correct identification by factory part number is what guarantees the exact form, fit, and function the design calls for.
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 90-series King Air, built from 1964 until the C90GTx concluded the line in 2021, launched what became the best-selling business turboprop family ever.
