Description
The 0552143-4 is a genuine Textron Aviation doubler — a reinforcing plate that locally strengthens an area of skin or structure. It is fitted to the Skyhawk. It carries an export classification of ECCN 9A991.
As an original-equipment (OEM) structural part supplied directly by Textron Aviation, the 0552143-4 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.
As a load-bearing element, a part in this role must match the original material and dimensions precisely to keep the airframe's engineered strength intact. Genuine factory parts carry the documentation and traceability that maintenance and airworthiness records depend on — assurance a look-alike substitute cannot provide.
OEM parts arrive to the specification the type design was certified against, preserving both airworthiness and the airframe's documented configuration. Fitting the correct factory part the first time avoids the rework, removal, and re-inspection that an incorrect or unapproved part can trigger.
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.
