2534-12 - FFC FAA-PMA Fuel Cell for King Air Aircraft

2534-12 – FFC FAA-PMA Main Wing Fuel Cell for King Air 200 Series

Available now on the Airparts.aero Marketplace.

Overview

The 2534-12 from FFC (Fuel Cell and Components) is a high-quality, FAA-PMA approved flexible fuel cell, engineered as a direct replacement for the Textron Aviation OEM part number 50-389034-12. This flight-critical bladder tank is designed for the main (outboard) wing fuel bays of the Beechcraft King Air B200 and B200GT aircraft. As a Parts Manufacturer Approval (PMA) holder, FFC has demonstrated to the Federal Aviation Administration that this fuel cell meets or exceeds the safety and performance standards of the original equipment part, making it a fully airworthy and certified alternative.

Constructed from advanced, multi-layered rubber and fabric composites, the 2534-12 is designed to fit perfectly within the wing structure to safely contain the aircraft's fuel. It provides an equivalent level of durability, fuel resistance, and quality as the OEM part, ensuring the long-term integrity of the aircraft's fuel system.

Key Features

• FAA-PMA Approved Replacement: Fully certified by the FAA as an airworthy, direct replacement for the specified OEM part, offering identical form, fit, and function.

• Direct Replacement for P/N 50-389034-12: Engineered specifically to replace the Textron Aviation main wing fuel cell for the King Air 200 series.

• Flexible Bladder-Type Construction: The pliable, multi-ply design allows for a precise fit into the irregular shape of the wing fuel bay, maximizing usable fuel volume.

• Multi-Ply, Puncture-Resistant Design: Features multiple layers of reinforced fabric laminated between specialized rubber compounds to provide exceptional strength and resistance to punctures and tearing.

• Meets or Exceeds OEM Specifications: The design, materials, and manufacturing processes have been rigorously tested and approved by the FAA to be at least equal to the original part.

• LH/RH Applicability: Designed for installation in either the left-hand or right-hand main wing fuel bay.

• Aircraft Models:

  • King Air B200

  • King Air B200GT

Note: Verification of applicability is the absolute responsibility of the installer. The aircraft's current Illustrated Parts Catalog (IPC) should be consulted to verify the OEM part number, for which this FFC part is a direct replacement.

Applications

• Sole Application: Primary containment and storage of Jet A/A1 fuel in the main (outboard) wing fuel bays of specified Beechcraft King Air models.

Why Choose 2534-12?

An FAA-PMA certified part, such as the FFC 2534-12, offers a combination of value and uncompromising safety. This is not a simple "aftermarket" part; it is a component that has undergone a rigorous FAA certification process to prove its equivalency to the OEM part. For operators, this provides a cost-effective option for replacing a life-limited component like a fuel cell, while being assured that the part is fully airworthy, certified, and will maintain the aircraft's original type design.

The airworthiness of an FAA-PMA part like the FFC 2534-12 is assured through the manufacturer's strict adherence to an FAA-approved quality control system. To obtain and maintain their PMA, a specialized manufacturer such as FFC must demonstrate complete process control over every aspect of production. This includes full material traceability, where the chemical composition and manufacturing lot of every batch of rubber and fabric is documented and verified. The hand lay-up and assembly process is governed by a detailed manufacturing plan, and the critical vulcanization cycle is precisely controlled in an autoclave to ensure complete cross-linking of the polymer. Finally, every single fuel cell that is produced undergoes a 100% inspection, including a multi-hour pressure decay leak test, to validate its integrity before it can be certified and released for installation. This rigorous, FAA-audited quality system ensures that every PMA part is a safe and reliable component.

Note: This is a flight-critical component. Its installation is a complex and labor-intensive task that must be performed by a certified A&P mechanic, preferably with direct experience in fuel cell replacement, in strict accordance with the aircraft maintenance manual. The fuel bay must be meticulously cleaned and inspected for any foreign objects or sharp edges prior to installation. Fuel cells have a finite service life and require specific storage conditions.

Documentation

FAA PMA documentation is publicly available on the FAA's Regulatory and Guidance Library (RGL). Installation instructions are provided by FFC and must be used in conjunction with the official Beechcraft King Air Maintenance Manual.
