Description
The S1891-48 is a genuine Textron Aviation clamp used to fasten, secure, or retain components during assembly of the airframe. It fits the Citation CJ1 or CJ1+, Citation Sovereign or Sovereign+, Citation X, Citation X+, Skyhawk, and Stationair. It carries an export classification of ECCN 9A991.
Supplied directly by Textron Aviation as an original-equipment (OEM) part, the S1891-48 meets the manufacturer's specification and keeps the aircraft configuration-correct, with clean traceability in the maintenance records.
Parts like this are shared across the Cessna Citation, Skyhawk, and Stationair 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. Traceable OEM hardware keeps an aircraft's maintenance records defensible at annual, pre-purchase, and pre-buy inspections.
Genuine factory parts carry the documentation and traceability that maintenance and airworthiness records depend on — assurance a look-alike substitute cannot provide. Sourcing the OEM part protects the airframe's configuration and keeps its service history consistent, which matters for both airworthiness and resale value.
Cessna traces to the company Clyde Cessna founded in Wichita, Kansas in 1927; Textron Inc. acquired it in 1992, and since 2014 it has anchored Textron Aviation alongside Beechcraft and Hawker. The Citation family is the best-selling line of business jets ever built, and more than 7,500 have been delivered worldwide.
