Description
The 0553053-4 is a genuine Textron Aviation firewall angle — a formed structural piece used to join, reinforce, or support airframe components. It fits the Skyhawk. It carries an export classification of ECCN 9A991, weighs 0.28 pounds, and measures 1.8 (L) x 0.6 (W) x 0.4 (H) Inches.
Because the 0553053-4 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.
Across the Cessna Skyhawk fleet, correctly identified factory parts like this keep every airframe consistent and configuration-correct.
As a load-bearing element, a part in this role must match the original material and dimensions precisely to keep the airframe's engineered strength intact. Genuine factory parts carry the documentation and traceability that maintenance and airworthiness records depend on — assurance a look-alike substitute cannot provide.
Choosing the genuine article over an unapproved part keeps mechanics' sign-offs clean and the aircraft's configuration exactly as certificated. 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.
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. With over 44,000 built, the Cessna Skyhawk is the best-selling aircraft ever made and is still produced today.
