Description
The MS21260L2RH is a genuine Textron Aviation terminal that typically forms part of an electrical or signal run. It is fitted to the King Air 100. It carries an export classification of ECCN EAR99.
Supplied directly by Textron Aviation as an original-equipment (OEM) part, the MS21260L2RH meets the manufacturer's specification and keeps the aircraft configuration-correct, with clean traceability in the maintenance records.
Because the Beechcraft King Air aircraft share extensive structure and hardware, a single part like this is often common across several variants.
Electrical and electronic components are defined by exact ratings and characteristics, so the specified part keeps the circuit performing as engineered. An unapproved or surplus substitute can introduce fit, material, or paperwork problems that surface at the next inspection; the genuine part avoids that risk.
Choosing the genuine article over an unapproved part keeps mechanics' sign-offs clean and the aircraft's configuration exactly as certificated. OEM parts arrive to the specification the type design was certified against, preserving both airworthiness and the airframe's documented configuration.
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.
Beechcraft was founded in Wichita, Kansas in 1932 by Walter and Olive Ann Beech, and has been part of Textron Aviation since 2014, uniting with Cessna and Hawker. The King Air first flew in 1964 and became the best-selling business turboprop in history — still built today as the King Air 260 and 360.
