HARNESS ASSEMBLY

The 000-170000-37 is a genuine Textron Aviation harness assembly that typically forms part of an electrical or signal run. It is fitted to the Baron Series B55, E55, 58 or G58, Bonanza 36, Bonanza F33, G33, F33A or F33C, King Air 100, and King Air B200, B200T, B200C or B200CT. It carries an export classification of ECCN 9A991. As an original-equipment (OEM) part supplied directly by Textron Aviation, the 000-170000-37 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. Across the Beechcraft Baron, Bonanza, and King Air fleet, correctly identified factory parts like this keep every airframe consistent and configuration-correct. Ratings, tolerances, and interfaces are what define an electrical part; matching the specified item keeps the system working as certified. Sourcing the OEM part protects the airframe's configuration and keeps its service history consistent, which matters for both airworthiness and resale value. Fitting the correct factory part the first time avoids the rework, removal, and re-inspection that an incorrect or unapproved part can trigger. 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 Baron, introduced in 1961 as a twin-engine development of the Bonanza, carried Beechcraft's reputation for solid handling into a capable light twin.
