Description
The MS21915J6-5 is a genuine Textron Aviation bushing corrosion resistant — a sleeve providing a bearing or protective surface at a pass-through or pivot. It carries an export classification of ECCN 9A991.
Fit and load rating define a bearing's job, so matching the specified part protects both function and service life. Genuine sourcing means the part matches the drawing exactly, so fit and function are known quantities rather than a gamble at installation.
Applicability should always be confirmed against the aircraft's IPC and effectivity records prior to fitting the part. Traceable OEM hardware keeps an aircraft's maintenance records defensible at annual, pre-purchase, and pre-buy inspections.
Part numbers can supersede over time, so verify the current applicable number for your airframe's serial and configuration before installation. An unapproved or surplus substitute can introduce fit, material, or paperwork problems that surface at the next inspection; the genuine part avoids that risk.
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. For a regulated aircraft component, correct identification by factory part number is what guarantees the exact form, fit, and function the design calls for.
Textron Aviation's roots reach back to Clyde Cessna's 1927 company and the Beech family's 1932 firm, both founded in Wichita, Kansas.
