Description
The 3940475-8 is a genuine Textron Aviation clamp block used to fasten, secure, or retain components during assembly of the airframe. It is fitted to the Skyhawk. It carries an export classification of ECCN 9A991, weighs 0.02 pounds, and measures 1.95 (L) x 0.6 (W) x 0.15 (H) Inches.
Supplied directly by Textron Aviation as an original-equipment (OEM) part, the 3940475-8 meets the manufacturer's specification and keeps the aircraft configuration-correct, with clean traceability in the maintenance records.
Across the Cessna Skyhawk fleet, correctly identified factory parts like this keep every airframe consistent and configuration-correct.
Fastening and retaining hardware may look simple, but grade, size, and finish are specified for the joint each secures — the correct part matters. Fitting the correct factory part the first time avoids the rework, removal, and re-inspection that an incorrect or unapproved part can trigger.
Sourcing the OEM part protects the airframe's configuration and keeps its service history consistent, which matters for both airworthiness and resale value. Genuine factory parts carry the documentation and traceability that maintenance and airworthiness records depend on — assurance a look-alike substitute cannot provide.
Genuine sourcing means the part matches the drawing exactly, so fit and function are known quantities rather than a gamble at installation.
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. With over 44,000 built, the Cessna Skyhawk is the best-selling aircraft ever made and is still produced today.
