Description
The 000-170000-125 is a genuine Textron Aviation skin skin assembly lower ext wi — the formed sheet-metal covering fastened over the underlying 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.
As an original-equipment (OEM) structural part supplied directly by Textron Aviation, the 000-170000-125 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.
Across the Beechcraft King Air fleet, correctly identified factory parts like this keep every airframe consistent and configuration-correct.
As a load-bearing element, a part in this role must match the original material and dimensions precisely to keep the airframe's engineered strength intact. Fitting the correct factory part the first time avoids the rework, removal, and re-inspection that an incorrect or unapproved part can trigger.
Built by Beechcraft — the Wichita, Kansas manufacturer founded in 1932 and part of Textron Aviation since 2014 — this part carries a name long associated with rugged, capable aircraft. 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.
