Description
The CB4021G3N8 is a genuine Textron Aviation mount cable tie that mounts, locates, or braces a component within the airframe. It is fitted to the Premier Model 390 and SkyCourier. It carries an export classification of ECCN EAR99, weighs 0.03 pounds, and measures 2 (L) x 1.3 (W) x 0.95 (H) Inches.
As an original-equipment (OEM) part supplied directly by Textron Aviation, the CB4021G3N8 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 Beechcraft Premier and Cessna SkyCourier aircraft share extensive structure and hardware, a single part like this is often common across several variants.
Electrical and electronic components are defined by exact ratings and characteristics, so the specified part keeps the circuit performing as engineered. Because substitutions on type-certificated aircraft require approved data, the genuine part is the straightforward, compliant choice for this application.
Traceable OEM hardware keeps an aircraft's maintenance records defensible at annual, pre-purchase, and pre-buy inspections. Because aircraft parts are governed by strict airworthiness and traceability rules, fitting the OEM part rather than an unapproved equivalent keeps the installation eligible and the aircraft's records clean.
These aircraft are built by Textron Aviation, which unites Cessna (founded 1927) and Beechcraft (founded 1932) under one Wichita, Kansas company since 2014. The Beechcraft Premier I was a clean-sheet, composite-fuselage light jet — the first jet Beechcraft designed in-house — supported today through Textron Aviation.
