Description
The 3642-12 is a genuine Textron Aviation plenum cap assembly supplied as a built-up assembly of several components in a single installable unit. It is fitted to the Skyhawk. It carries an export classification of ECCN 9A991.
Because the 3642-12 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 factory-supplied item for a type-certificated aircraft, this part is defined by the manufacturer's specification and applicability data. The value of an OEM part is as much in its paperwork and pedigree as its metal — both of which an aircraft's records require.
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. Traceable OEM hardware keeps an aircraft's maintenance records defensible at annual, pre-purchase, and pre-buy inspections.
On a certificated airframe, part provenance matters as much as the part itself; genuine factory sourcing settles that question up front.
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. 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.
