Description
The 0523921-0 is a genuine Textron Aviation component supplied for use on the aircraft, with its precise function defined by the aircraft's parts data. It is fitted to the Skyhawk and Skylane. It carries an export classification of ECCN EAR99.
Supplied directly by Textron Aviation as an original-equipment (OEM) part, the 0523921-0 meets the manufacturer's specification and keeps the aircraft configuration-correct, with clean traceability in the maintenance records.
Parts like this are shared across the Cessna Skyhawk and Skylane aircraft, reflecting how much structure and hardware these models have in common.
As a factory-supplied item for a type-certificated aircraft, this part is defined by the manufacturer's specification and applicability data. Fitting the correct factory part the first time avoids the rework, removal, and re-inspection that an incorrect or unapproved part can trigger.
Because substitutions on type-certificated aircraft require approved data, the genuine part is the straightforward, compliant choice for this application. Choosing the genuine article over an unapproved part keeps mechanics' sign-offs clean and the aircraft's configuration exactly as certificated.
On a certificated airframe, part provenance matters as much as the part itself; genuine factory sourcing settles that question up front.
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.
