FGFB244004203A1 – Dassault Falcon OEM Preformed Seal

Available now on the Airparts.aero Marketplace.

Overview

The Dassault Falcon FGFB244004203A1 is a flight-critical, OEM preformed high-temperature fire seal, an essential aerodynamic and safety component for the engine pylon-to-wing fairing on various Falcon business jets. This is not a simple weatherstrip; it is a precision-molded, multi-layer seal engineered to perform two critical functions. Aerodynamically, it creates a smooth, uninterrupted surface to reduce drag. Critically, it also acts as a fireproof barrier, designed to prevent the propagation of fire from the engine pylon into the wing structure. The FGFB244004203A1 is manufactured from advanced, fire-resistant silicone with an integrated fiberglass reinforcement.

Its integrity is fundamental to the aircraft's aerodynamic efficiency and its certified fire-containment capabilities, making it a cornerstone of the Falcon jet's safety design.

Key Features

• Fireproof Barrier Seal: Its most critical function is to maintain the integrity of the firewall boundary between the engine pylon and the main wing structure. It is designed to withstand a 2000°F flame for 15 minutes without burn-through, as required by transport-category aircraft certification.

• High-Temperature Silicone & Fiberglass Construction: Fabricated from a high-grade, fire-resistant red silicone rubber compound. This material is reinforced with an internal layer of woven fiberglass fabric, which provides exceptional strength and prevents the seal from shrinking or melting when exposed to extreme heat.

• Aerodynamic Fairing: The seal is preformed with a specific and complex aerodynamic profile. This shape is engineered to provide a perfectly smooth and faired transition between the engine pylon and the wing, minimizing parasitic drag and preventing the generation of aerodynamic noise.

• Environmental Sealing: Creates a durable, weather-tight barrier that prevents water, de-icing fluid, and other contaminants from entering the pylon-to-wing attachment structure, which is critical for preventing hidden corrosion.

• Genuine Dassault Falcon OEM Part: As a genuine factory component, it guarantees the correct material composition, fire-resistant properties, and precise profile required for a perfect, airworthy fit on a Falcon jet.

Why Choose FGFB244004203A1?

An engine fire is one of the most critical emergencies in aviation. The pylon fire seals are the primary barriers that prevent such a fire from spreading to the main wing structure and fuel tanks. The Dassault Falcon FGFB244004203A1 is the only seal certified by the manufacturer to provide this life-saving protection. Using a genuine OEM part is the only way to ensure the seal has the correct, certified fire-resistant material and the precise profile to function as an effective fire and aerodynamic seal.

The Dassault Falcon FGFB244004203A1 is a high-performance elastomeric fire seal. The red silicone base material is specifically compounded with additives that cause it to form a stable, non-combustible silica (

) char when exposed to a direct flame. The internal fiberglass reinforcement provides a critical structural backbone, preventing the seal from shrinking or being consumed by the fire, ensuring it stays in place as a physical barrier. This combination of "intumescent" char-forming and structural reinforcement is what allows the seal to meet the rigorous "15-minute, 2000°F" burn-through resistance requirement mandated by the FAA and EASA for components that serve a firewall function. Its aerodynamic profile is equally important, as it is designed to maintain a laminar flow attachment at a critical juncture, reducing drag and improving aircraft performance.

Note: This is a flight-critical, primary airframe and fire protection component. Installation must be performed by a certified AME or A&P mechanic with experience in Falcon jet airframes, in strict accordance with the current Dassault Aviation maintenance manual. Proper surface preparation and the use of specified adhesives are mandatory for an airworthy installation.
