Description
The 0543021-1 is a genuine Textron Aviation tube of a type generally used to route fluid, air, or wiring through the airframe. It fits the Skyhawk. It carries an export classification of ECCN 9A991.
Because the 0543021-1 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.
Because the Cessna Skyhawk aircraft share extensive structure and hardware, a single part like this is often common across several variants.
Fluid- and air-system components are rated for specific pressures, media, and fittings, so the correct part is essential to a safe, leak-free system. Because substitutions on type-certificated aircraft require approved data, the genuine part is the straightforward, compliant choice for this application.
An unapproved or surplus substitute can introduce fit, material, or paperwork problems that surface at the next inspection; the genuine part avoids that risk. Traceable OEM hardware keeps an aircraft's maintenance records defensible at annual, pre-purchase, and pre-buy inspections.
The factory part is built to the manufacturer's material and dimensional specification, so it installs as designed without the surprises a generic equivalent can bring.
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.
