Description
The MS21047-5K is a genuine Textron Aviation nut used to fasten, secure, or retain components during assembly of the airframe. It is fitted to the Skyhawk. It carries an export classification of ECCN EAR99.
Supplied directly by Textron Aviation as an original-equipment (OEM) part, the MS21047-5K meets the manufacturer's specification and keeps the aircraft configuration-correct, with clean traceability in the maintenance records.
Because the Cessna Skyhawk aircraft share extensive structure and hardware, a single part like this is often common across several variants.
Aircraft hardware is called out to a specific specification for each location; an off-the-shelf equivalent is rarely acceptable. On a certificated airframe, part provenance matters as much as the part itself; genuine factory sourcing settles that question up front.
An unapproved or surplus substitute can introduce fit, material, or paperwork problems that surface at the next inspection; the genuine part avoids that risk. Sourcing the OEM part protects the airframe's configuration and keeps its service history consistent, which matters for both airworthiness and resale value.
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.
Built by Textron Aviation, whose Cessna line was founded in Wichita, Kansas in 1927 and joined Textron in 1992, this part carries one of general aviation's most storied names. With over 44,000 built, the Cessna Skyhawk is the best-selling aircraft ever made and is still produced today.
