BOLT, SHEAR SHORT THREAD

The NAS1103-4D is a genuine Textron Aviation bolt shear short thread — a fastening or retaining hardware item used in the airframe. It is fitted to the Baron Series B55, E55, 58 or G58, Bonanza 36, and Skyhawk. It carries an export classification of ECCN EAR99. Supplied directly by Textron Aviation as an original-equipment (OEM) part, the NAS1103-4D 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 Baron, Beechcraft Bonanza, and Cessna Skyhawk 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. 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. 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 Baron, introduced in 1961 as a twin-engine development of the Bonanza, carried Beechcraft's reputation for solid handling into a capable light twin.
