Description
The S1066C1 is a genuine Textron Aviation washer used to fasten, secure, or retain components during assembly of the airframe. It is fitted to the Caravan or Grand Caravan EX and Skyhawk. It carries an export classification of ECCN EAR99, weighs 0.01 pounds, and measures 0.2 (L) x 0.2 (W) x 0.1 (H) Inches.
As an original-equipment (OEM) part supplied directly by Textron Aviation, the S1066C1 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 Caravan and Skyhawk aircraft share extensive structure and hardware, a single part like this is often common across several variants.
Strength grade and finish define aircraft hardware, so matching the specified part keeps the joint as designed. Because substitutions on type-certificated aircraft require approved data, the genuine part is the straightforward, compliant choice for this application.
Genuine factory parts carry the documentation and traceability that maintenance and airworthiness records depend on — assurance a look-alike substitute cannot provide.
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. Cessna's single-engine Caravan turboprop, in production since 1984, is one of the most widely used utility aircraft in the world.
