Description
The MS24394D5 is a genuine Textron Aviation elbow oxygen supplied for use on the aircraft, with its precise function defined by the aircraft's parts data. It is fitted to the 1900 Airliner. It carries an export classification of ECCN EAR99.
Supplied directly by Textron Aviation as an original-equipment (OEM) part, the MS24394D5 meets the manufacturer's specification and keeps the aircraft configuration-correct, with clean traceability in the maintenance records.
Because the Beechcraft 1900 aircraft share extensive structure and hardware, a single part like this is often common across several variants.
As a factory-supplied item for a type-certificated aircraft, this part is defined by the manufacturer's specification and applicability data. 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.
Traceable OEM hardware keeps an aircraft's maintenance records defensible at annual, pre-purchase, and pre-buy inspections. 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.
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. Derived from the King Air, the 19-passenger Beechcraft 1900 airliner (built 1982–2002) remains in service with regional and cargo operators.
