Description
The 3930421-1 is a genuine Textron Aviation circuit breaker pnl assembly of a type used within the aircraft's avionics or electrical circuits. It fits the Skyhawk. It carries an export classification of ECCN 9A991.
Supplied directly by Textron Aviation as an original-equipment (OEM) part, the 3930421-1 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.
Ratings, tolerances, and interfaces are what define an electrical part; matching the specified item keeps the system working as certified. Traceable OEM hardware keeps an aircraft's maintenance records defensible at annual, pre-purchase, and pre-buy inspections.
For a regulated aircraft component, correct identification by factory part number is what guarantees the exact form, fit, and function the design calls for. Fitting the correct factory part the first time avoids the rework, removal, and re-inspection that an incorrect or unapproved part can trigger.
Genuine sourcing means the part matches the drawing exactly, so fit and function are known quantities rather than a gamble at installation.
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.
