Description
The 3619181-13 is a genuine Textron Aviation step blanket aft used for thermal or acoustic protection within the airframe. It is fitted to the Citation Latitude. It carries an export classification of ECCN 9A991.
Because the 3619181-13 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 Citation fleet, correctly identified factory parts like this keep every airframe consistent and configuration-correct.
Its rating for heat or sound is what makes an insulation part work, so the correct specified material matters in service. Because aircraft parts are governed by strict airworthiness and traceability rules, fitting the OEM part rather than an unapproved equivalent keeps the installation eligible and the aircraft's records clean.
Traceable OEM hardware keeps an aircraft's maintenance records defensible at annual, pre-purchase, and pre-buy inspections. Because this is a component for a type-certificated aircraft, using the manufacturer's part keeps the installation within approved configuration and simplifies compliance.
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 Citation family is the best-selling line of business jets ever built, and more than 7,500 have been delivered worldwide.
