Description
The MS24524-28 is a genuine Textron Aviation switch used to make or break an electrical circuit. It fits the 1900D Airliner. It carries an export classification of ECCN 9A991.
Because the MS24524-28 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.
Because the Beechcraft 1900 aircraft share extensive structure and hardware, a single part like this is often common across several variants.
In an aircraft's electrical system, using the correct component preserves the circuit's designed behavior, reliability, and safety. Genuine sourcing means the part matches the drawing exactly, so fit and function are known quantities rather than a gamble at installation.
Fitting the correct factory part the first time avoids the rework, removal, and re-inspection that an incorrect or unapproved part can trigger. OEM parts arrive to the specification the type design was certified against, preserving both airworthiness and the airframe's documented configuration.
On a certificated airframe, part provenance matters as much as the part itself; genuine factory sourcing settles that question up front.
Beechcraft, founded in Wichita, Kansas in 1932, joined Cessna and Hawker under Textron Aviation in 2014, which today supports the worldwide Beechcraft fleet with genuine factory parts. The Beechcraft 1900, a 19-passenger regional airliner derived from the King Air, was produced from 1982 to 2002 and still serves commuter and cargo operators worldwide.
