Description
The S51-20-4 is a genuine Textron Aviation hose that typically routes a fluid, air, or electrical run through the aircraft. It is fitted to the Skyhawk and Skylane. It carries an export classification of ECCN EAR99, weighs 0.05 pounds, and measures 1.65 (L) x 1.65 (W) x 1.15 (H) Inches.
Supplied directly by Textron Aviation as an original-equipment (OEM) part, the S51-20-4 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.
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. Sourcing the OEM part protects the airframe's configuration and keeps its service history consistent, which matters for both airworthiness and resale value.
OEM parts arrive to the specification the type design was certified against, preserving both airworthiness and the airframe's documented configuration. Because substitutions on type-certificated aircraft require approved data, the genuine part is the straightforward, compliant choice for this application.
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. The Cessna 172 Skyhawk is the most-produced aircraft in history, with more than 44,000 built since 1956, and remains in production under Textron Aviation.
