Description
The Y-16440-2-148 is a genuine Textron Aviation left-hand spacer lower upper that establishes proper spacing or alignment in an assembly. It fits the Skyhawk.
As an original-equipment (OEM) part supplied directly by Textron Aviation, the Y-16440-2-148 is built to the aircraft maker's specification and cross-references the type design as documented in the maintenance data. Choosing the genuine part over an unapproved substitute preserves configuration control and simplifies inspection sign-offs.
Because the Cessna Skyhawk aircraft share extensive structure and hardware, a single part like this is often common across several variants.
Fastening and retaining hardware may look simple, but grade, size, and finish are specified for the joint each secures — the correct part matters. Genuine sourcing means the part matches the drawing exactly, so fit and function are known quantities rather than a gamble at installation.
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. Using the factory part number preserves configuration control, so the airframe stays consistent with its approved type design and the work is straightforward to sign off at inspection.
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.
