Overview

The Textron Aviation 50-389029-8 is a genuine Original Equipment Manufacturer (OEM), all-inclusive kit featuring the right-hand (RH) nacelle fuel cell for the Beechcraft King Air 90 series of aircraft. This is a complete solution for fuel cell replacement, as the "-8" part number designation signifies a comprehensive kit that includes the 61-gallon bladder cell plus all the necessary single-use gaskets, seals, and O-rings required for a proper, airworthy installation. Manufactured to Textron's exact specifications from a modern, lightweight polymer, this fuel cell provides superior durability and resistance to modern aviation fuels, ensuring the utmost in safety and reliability for your aircraft's fuel system.

Key Features

• Complete Installation Kit: This kit provides a comprehensive solution by bundling the right-hand fuel cell with all the new, factory-certified seals and gaskets needed for the fuel quantity transmitter, drain valves, and filler neck. This prevents the reuse of old, compressed gaskets that could lead to leaks.
• Lightweight & Durable Polymer: Fabricated from a high-strength, lightweight polymer compound. This advanced material offers excellent longevity and resistance to degradation from Jet A and other aviation fuels, and provides a weight savings compared to older rubber compounds.
• Vulcanized Seam Construction: Constructed using state-of-the-art thermal vulcanization for all seams. This process creates a monolithic bond that is stronger than the surrounding material, eliminating the seam as a potential weak point and ensuring a robust, leak-proof bladder.
• Perfect OEM Fit: As a genuine Textron Aviation part, it is built on the original factory tooling, guaranteeing a perfect, drop-in fit into the King Air's right-hand nacelle structure. All fittings, snaps, and ports are precisely located for seamless integration with the aircraft's fuel plumbing.
• Flight-Critical Safety Component: The integrity of the fuel cell is paramount. This OEM kit ensures every component, from the bladder itself to the smallest O-ring, meets the stringent quality and safety standards of the original aircraft Type Certificate.

The 50-389029-8 is a bladder-type fuel cell, designed to fit within a rigid cavity in the aircraft's right-hand nacelle structure. This design provides several advantages, including ease of replacement compared to an integrated or "wet wing" tank. The lightweight, flexible polymer construction allows the large cell to be installed through a relatively small access panel. The material is also more resistant to cracking from structural flexing than a rigid tank. The included installation kit is a critical part of the system's reliability. Each time a fitting is removed, the old gasket or O-ring takes a "compression set" and work-hardens, meaning it will not provide a reliable seal if reused. The comprehensive kit ensures every seal is fresh, providing a leak-proof installation.

Note: Fuel cell installation is a complex and hazardous maintenance task that must be performed by a certified A&P mechanic with experience in this specific procedure, in strict accordance with the current Textron Aviation maintenance manual. The fuel system must be completely drained and purged, and all safety precautions for working in a fuel vapor environment must be observed.
