Description
The MS51957-32 is a genuine Textron Aviation screw — a fastening or retaining hardware item used in the airframe. It is fitted to the Beechjet 400/400A, Premier Model 390, Skyhawk, and Skylane. It carries an export classification of ECCN EAR99.
As an original-equipment (OEM) part supplied directly by Textron Aviation, the MS51957-32 is built to the aircraft maker's specification and cross-references the type design as documented in the maintenance data. Choosing the genuine part over an unapproved substitute preserves configuration control and simplifies inspection sign-offs.
Parts like this are shared across the Beechcraft, Beechcraft Premier, Cessna Skyhawk, and Cessna Skylane aircraft, reflecting how much structure and hardware these models have in common.
Strength grade and finish define aircraft hardware, so matching the specified part keeps the joint as designed. OEM parts arrive to the specification the type design was certified against, preserving both airworthiness and the airframe's documented configuration.
Genuine factory parts carry the documentation and traceability that maintenance and airworthiness records depend on — assurance a look-alike substitute cannot provide. Genuine sourcing means the part matches the drawing exactly, so fit and function are known quantities rather than a gamble at installation.
Both the Cessna and Beechcraft lines are supported today by Textron Aviation, formed in 2014 to unite the two historic Wichita manufacturers with Hawker. The Beechjet 400, which began life as the Mitsubishi Diamond and later became the Hawker 400, is a light business jet supported today through Textron Aviation.
