Description
The NAS1090-3 is a genuine Textron Aviation chain hook supplied for use on the aircraft, with its precise function defined by the aircraft's parts data. It is fitted to the 1900D Airliner, King Air 350 Fusion, King Air 350C FM-36 & On, King Air 350C Fusion, King Air 350i, King Air 360, King Air 360C, and Skyhawk. It carries an export classification of ECCN EAR99, weighs 0.01 pounds, and measures 1.05 (L) x 0.6 (W) x 0.15 (H) Inches.
Because the NAS1090-3 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.
Because the Beechcraft 1900, Beechcraft King Air, and Cessna Skyhawk aircraft share extensive structure and hardware, a single part like this is often common across several variants.
Supplied as a defined part in the manufacturer's catalog, its exact role is set by the aircraft's parts and maintenance data. Because substitutions on type-certificated aircraft require approved data, the genuine part is the straightforward, compliant choice for this application.
Sourcing the OEM part protects the airframe's configuration and keeps its service history consistent, which matters for both airworthiness and resale value.
These aircraft are built by Textron Aviation, which unites Cessna (founded 1927) and Beechcraft (founded 1932) under one Wichita, Kansas company since 2014. Derived from the King Air, the 19-passenger Beechcraft 1900 airliner (built 1982–2002) remains in service with regional and cargo operators.
