Description
The MS21207-8F10 is a genuine Textron Aviation screw tapping 100deg csk — a fastening or retaining hardware item used in the airframe. 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 EAR99.
Because the MS21207-8F10 is an original-equipment (OEM) part sourced directly from Textron Aviation, it matches the exact specification and placement called out in the aircraft's type design and maintenance data — assurance a generic substitute cannot offer.
Parts like this are shared across the Beechcraft King Air aircraft, reflecting how much structure and hardware these models have in common.
Strength grade and finish define aircraft hardware, so matching the specified part keeps the joint as designed. 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.
OEM parts arrive to the specification the type design was certified against, preserving both airworthiness and the airframe's documented configuration.
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.
