Description
The MS21964-20 is a genuine Textron Aviation connector that typically forms part of an electrical or signal run.
In an aircraft's electrical system, using the correct component preserves the circuit's designed behavior, reliability, and safety. 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.
Applicability should always be confirmed against the aircraft's IPC and effectivity records prior to fitting the part. Genuine sourcing means the part matches the drawing exactly, so fit and function are known quantities rather than a gamble at installation.
Because a single part number can be superseded or vary by effectivity, confirm applicability against your aircraft's Illustrated Parts Catalog (IPC) and serial-number effectivity before ordering. On a certificated airframe, part provenance matters as much as the part itself; genuine factory sourcing settles that question up front.
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. 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 — parent of the Cessna, Beechcraft, and Hawker lines — supports this part through its genuine factory parts network.
