NUT

The AS5178-03 is a genuine Textron Aviation nut — a fastening or retaining hardware item used in the airframe. It fits the Bonanza 36, Caravan or Grand Caravan EX, Skyhawk, Skylane, and Stationair. It carries an export classification of ECCN EAR99, weighs 0.01 pounds, and measures 0.62 (L) x 0.62 (W) x 0.22 (H) Inches. Supplied directly by Textron Aviation as an original-equipment (OEM) part, the AS5178-03 meets the manufacturer's specification and keeps the aircraft configuration-correct, with clean traceability in the maintenance records. Parts like this are shared across the Beechcraft Bonanza, Cessna Caravan, Cessna Skyhawk, Cessna Skylane, and Cessna Stationair aircraft, reflecting how much structure and hardware these models have in common. Aircraft hardware is called out to a specific specification for each location; an off-the-shelf equivalent is rarely acceptable. The value of an OEM part is as much in its paperwork and pedigree as its metal — both of which an aircraft's records require. For a regulated aircraft component, correct identification by factory part number is what guarantees the exact form, fit, and function the design calls for. 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 Beechcraft Bonanza is widely regarded as holding the longest production run of any aircraft — from its 1947 debut until Textron announced in November 2025 that it would wind down Bonanza and Baron production as the order backlog clears.
