Description
The 0553046-4 is a genuine Textron Aviation spacer used to set correct clearance, alignment, or fit between parts. It fits the Skyhawk. It carries an export classification of ECCN 9A991.
Because the 0553046-4 is an original-equipment (OEM) part sourced directly from Textron Aviation, it matches the exact specification and placement called out in the aircraft's type design and maintenance data — assurance a generic substitute cannot offer.
Parts like this are shared across the Cessna Skyhawk aircraft, reflecting how much structure and hardware these models have in common.
Fastening and retaining hardware may look simple, but grade, size, and finish are specified for the joint each secures — the correct part matters. 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.
Because substitutions on type-certificated aircraft require approved data, the genuine part is the straightforward, compliant choice for this application. Using the factory part number preserves configuration control, so the airframe stays consistent with its approved type design and the work is straightforward to sign off at inspection.
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.
