Description
The MS24187-D1 is a genuine Textron Aviation relay that controls an electrical circuit aboard the aircraft. It fits the Caravan or Grand Caravan EX, King Air C90GTi, and King Air C90GTx. It carries an export classification of ECCN EAR99, weighs 0.56 lbs, and measures 3.1 (L) x 2.6 (W) x 1.8 (H) in.
Because the MS24187-D1 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.
Parts like this are shared across the Cessna Caravan and Beechcraft King Air aircraft, reflecting how much structure and hardware these models have in common.
Ratings, tolerances, and interfaces are what define an electrical part; matching the specified item keeps the system working as certified. Because aircraft parts are governed by strict airworthiness and traceability rules, fitting the OEM part rather than an unapproved equivalent keeps the installation eligible and the aircraft's records clean.
Because this is a component for a type-certificated aircraft, using the manufacturer's part keeps the installation within approved configuration and simplifies compliance.
These aircraft are built by Textron Aviation, which unites Cessna (founded 1927) and Beechcraft (founded 1932) under one Wichita, Kansas company since 2014. Cessna's single-engine Caravan turboprop, in production since 1984, is one of the most widely used utility aircraft in the world.
