Description
The MS21916-6-4 is a genuine Textron Aviation union supplied for use on the aircraft, with its precise function defined by the aircraft's parts data. It is fitted to the Citation III, VI or VII and Citation Latitude. It carries an export classification of ECCN EAR99, weighs 0.07 pounds, and measures 0.85 (L) x 1.2 (W) x 0.85 (H) Inches.
As an original-equipment (OEM) part supplied directly by Textron Aviation, the MS21916-6-4 is built to the aircraft maker's specification and cross-references the type design as documented in the maintenance data. Choosing the genuine part over an unapproved substitute preserves configuration control and simplifies inspection sign-offs.
Because the Cessna Citation aircraft share extensive structure and hardware, a single part like this is often common across several variants.
As a factory-supplied item for a type-certificated aircraft, this part is defined by the manufacturer's specification and applicability data. For a regulated aircraft component, correct identification by factory part number is what guarantees the exact form, fit, and function the design calls for.
Genuine sourcing means the part matches the drawing exactly, so fit and function are known quantities rather than a gamble at installation.
Built by Textron Aviation, whose Cessna line was founded in Wichita, Kansas in 1927 and joined Textron in 1992, this part carries one of general aviation's most storied names. The Citation family is the best-selling line of business jets ever built, and more than 7,500 have been delivered worldwide.
