Description
The 0511819-2 is a genuine Textron Aviation doubler ELT antenna used to reinforce and locally strengthen a skin or structural member. It is applicable to the Skyhawk. It carries an export classification of ECCN 9A991.
Because the 0511819-2 is an original-equipment (OEM) structural component from Textron Aviation, it is built to the airframe manufacturer's specification and matches the type design as documented. Fitting the genuine part preserves the wing or airframe's engineered strength and keeps installation and inspection records clean.
Across the Cessna Skyhawk fleet, correctly identified factory parts like this keep every airframe consistent and configuration-correct.
Structural parts like this carry and transfer loads through the airframe, so exact form and fit are essential to preserving the design's strength and fatigue life. Choosing the genuine article over an unapproved part keeps mechanics' sign-offs clean and the aircraft's configuration exactly as certificated.
Traceable OEM hardware keeps an aircraft's maintenance records defensible at annual, pre-purchase, and pre-buy inspections. OEM parts arrive to the specification the type design was certified against, preserving both airworthiness and the airframe's documented configuration.
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.
