BEARING

The S1003-66A is a genuine Textron Aviation bearing that supports rotational or pivoting motion within a mechanism. It is fitted to the Citation X, Citation X+, and Skyhawk. It carries an export classification of ECCN 9A991. As an original-equipment (OEM) part supplied directly by Textron Aviation, the S1003-66A 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. Parts like this are shared across the Cessna Citation and Skyhawk aircraft, reflecting how much structure and hardware these models have in common. A bearing or bushing sets how a shaft or pivot moves and wears; the right part keeps that motion as designed. Genuine factory parts carry the documentation and traceability that maintenance and airworthiness records depend on — assurance a look-alike substitute cannot provide. The factory part is built to the manufacturer's material and dimensional specification, so it installs as designed without the surprises a generic equivalent can bring. 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.
