SEAL

The 154-01300 is a genuine Textron Aviation seal that seals a joint or opening against air, fluid, or contamination. It is applicable to the Baron Series B55, E55, 58 or G58, Skyhawk, and Skylane. It carries an export classification of ECCN 9A991, weighs 0.01 lbs, and measures 2.5 (L) x 2.45 (W) x 0.2 (H) in. Supplied directly by Textron Aviation as an original-equipment (OEM) part, the 154-01300 meets the manufacturer's specification and keeps the aircraft configuration-correct, with clean traceability in the maintenance records. Because the Beechcraft Baron, Cessna Skyhawk, and Cessna Skylane aircraft share extensive structure and hardware, a single part like this is often common across several variants. A seal or gasket keeps a joint tight against its service conditions; only the specified part reliably maintains that integrity. Because aircraft parts are governed by strict airworthiness and traceability rules, fitting the OEM part rather than an unapproved equivalent keeps the installation eligible and the aircraft's records clean. 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. These aircraft are built by Textron Aviation, which unites Cessna (founded 1927) and Beechcraft (founded 1932) under one Wichita, Kansas company since 2014. The Baron — a twin-engine member of Beechcraft's piston line introduced in 1961 — shares much of its structure and hardware with the Bonanza.
