Description
The 3930378-23 is a genuine Textron Aviation channel support — a formed structural piece used to join, reinforce, or support airframe components. It is applicable to the Skyhawk. It carries an export classification of ECCN 9A991.
As an original-equipment (OEM) structural part supplied directly by Textron Aviation, the 3930378-23 is manufactured to the aircraft maker's specification for material, dimensions, and finish, and cross-references the type design exactly as documented in the maintenance data. For a structural member, the genuine correctly identified part preserves the engineered load paths and keeps the airframe configuration-correct.
Because the Cessna Skyhawk aircraft share extensive structure and hardware, a single part like this is often common across several variants.
Airframe structure of this kind is engineered to specific load paths; the correct part is what keeps those paths — and the aircraft's certified strength — unchanged. Fitting the correct factory part the first time avoids the rework, removal, and re-inspection that an incorrect or unapproved part can trigger.
Choosing the genuine article over an unapproved part keeps mechanics' sign-offs clean and the aircraft's configuration exactly as certificated. For a regulated aircraft component, correct identification by factory part number is what guarantees the exact form, fit, and function the design calls for.
The Cessna name is among the most recognized in aviation — founded in Wichita, Kansas in 1927 and part of Textron since 1992, today a cornerstone of Textron Aviation. With over 44,000 built, the Cessna Skyhawk is the best-selling aircraft ever made and is still produced today.
