FILTER

The B3-5-1 is a genuine Textron Aviation filter used to clean fluid or air in an aircraft system. It is fitted to the 1900 Airliner, 1900C Airliner, 1900D Airliner, Caravan or Grand Caravan EX, King Air 100, King Air 350 Fusion, King Air 350C FM-36 & On, King Air 350C Fusion, King Air 350i, and King Air 360, among other compatible variants. It carries an export classification of ECCN 9A991, weighs 0.01 lbs, and measures 3.05 (L) x 1.25 (W) x 0.65 (H) in. As an original-equipment (OEM) part supplied directly by Textron Aviation, the B3-5-1 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 1900, Cessna Caravan, Beechcraft King Air, Cessna Skyhawk, Cessna Skylane, and Cessna Stationair aircraft, reflecting how much structure and hardware these models have in common. Because it handles pressurized fluid or air, a component like this is specified precisely for its service — the right part keeps the system sound. These aircraft are built by Textron Aviation, which unites Cessna (founded 1927) and Beechcraft (founded 1932) under one Wichita, Kansas company since 2014. Derived from the King Air, the 19-passenger Beechcraft 1900 airliner (built 1982–2002) remains in service with regional and cargo operators.
