50-389034-11 - Textron Aviation OEM Fuel Cell Installation Kit

50-389034-11 – Textron Aviation Fuel Cell Installation Kit for Baron/Bonanza

Available now on the Airparts.aero Marketplace.

The Textron Aviation 50-389034-11 is a genuine Beechcraft OEM installation kit, representing the complete bill of materials required for the proper re-installation of a leading edge fuel cell in specific Beechcraft Baron and Bonanza model aircraft. This is not a single part, but a comprehensive collection of all the flight-critical, mandatory-replacement gaskets, seals, packings, and hardware that must be replaced any time a fuel cell is removed for maintenance or replacement. The integrity of the aircraft's fuel system and the safety of flight are directly dependent on the correct use of these certified components.

Sourcing each individual component separately is time-consuming and risks the procurement of incorrect or non-certified parts. This Textron-kitted solution guarantees that every single component—from the access panel gaskets to the smallest O-rings and washers—is the correct OEM part, manufactured from the specified Avgas-compatible materials. It is the only way to ensure the fuel system is returned to an airworthy, leak-free condition in strict accordance with the manufacturer's maintenance procedures.

Key Features

• Genuine Textron Aviation OEM Kit: The factory-authorized collection of parts required for a compliant and airworthy fuel cell installation on Baron and Bonanza aircraft.

• Contains All Mandatory Replacement Components: Includes the specific assortment of new, single-use gaskets and seals required to guarantee a durable, leak-free seal.

• Ensures Fuel System Integrity: Using this kit is the primary defence against post-maintenance fuel leaks, which are a catastrophic fire hazard in a piston aircraft engine environment.

• Certified Avgas-Resistant Materials: Every elastomeric component in the kit is made from a specific compound (typically Nitrile - NBR) engineered for long-term compatibility with aviation gasoline (100LL).

• Simplifies Procurement and Maintenance: Provides all necessary components in a single part number, streamlining the ordering process and ensuring the mechanic has all required items on hand.

Technical Specifications

• Part Number: 50-389034-11

Aircraft Compatibility

This installation kit is specifically designed for the leading edge fuel cells on various models of the Beechcraft Baron and Bonanza. Common applicable models include, but are not limited to:

• Beechcraft Baron 58, 58A

• Beechcraft Bonanza A36, G36

Crucial Note: The specific aircraft model and serial number must be checked against the latest revision of the official Textron Aviation (Beechcraft) Illustrated Parts Catalog (IPC) to ensure correct part number applicability.

Applications

• Mandatory for use any time a leading edge fuel cell is removed and reinstalled for repair or replacement on the specified aircraft models.

• Used during major airframe inspections and structural repairs that require fuel cell removal.

Why Choose 50-389034-11?

Choosing the genuine Textron 50-389034-11 kit is a non-negotiable decision for safety and airworthiness. A fuel leak, particularly within the wing structure firewall-forward of the cabin, is one of the most hazardous situations in aviation. Re-using old, compressed gaskets or substituting hardware store components for certified fasteners and seals introduces an unacceptable level of risk. This OEM kit is the only way to guarantee that every single component is dimensionally correct, made from the proper Avgas-impermeable material, and meets the quality standards of the aircraft's original type design.

The material science behind the components in the 50-389034-11 kit is critical to its function. The seals and gaskets are manufactured from a specific grade of Nitrile rubber (NBR), an elastomer chosen for its excellent resistance to the aromatic hydrocarbon content of aviation gasoline (100LL). Aromatic compounds are aggressive solvents that cause significant swelling and rapid degradation in incompatible elastomers. The high acrylonitrile (ACN) content in the NBR polymer specified by the OEM provides the necessary chemical resistance to prevent this, ensuring the seals maintain their durometer and compressive force over their service life. The kit may also include lacing cord, typically braided Dacron or a similar high-strength, low-stretch polyester fiber. This cord is used to properly suspend and position the flexible bladder within the wing cavity, preventing chafing against the aluminum structure and ensuring the cell's weight is properly distributed, which is critical for long-term durability.

Note: This kit contains flight-critical, single-use components. All gaskets, seals, and specified fasteners are designed to be replaced every time a fuel cell is removed. Re-using old seals will result in a fuel leak and a severe fire hazard. Fuel cell installation is a complex and critical maintenance task that must be performed by a certified A&P mechanic with experience in aircraft fuel systems, in strict accordance with the Textron Aviation maintenance manual for the specific aircraft model.
