3010880 - Pratt and Whitney Genuine OEM Igniter Gasket

3010880 – Pratt and Whitney OEM Igniter Gasket

Available now on the Airparts.aero Marketplace.

Overview

The 3010880 is a genuine OEM, flight-critical igniter gasket, engineered by Pratt & Whitney Canada (P&WC) for the legendary PT6A series of turboprop engines. This is not a standard gasket; it is a precision-manufactured, single-use "crush" gasket designed to create a perfect, gas-tight seal between the turbine igniter plug and the engine's combustor case. Fabricated from a soft, high-temperature metal alloy, the 3010880 is essential for containing the immense pressures and temperatures of the combustion chamber, ensuring the safety and performance of the engine.

Key Features

• High-Pressure Combustion Seal: Its sole purpose is to create a perfect, leak-proof seal at the igniter boss. It is designed to contain the high-pressure, superheated gases within the combustion chamber, preventing dangerous leaks into the engine nacelle.
• Soft Metal "Crush" Design: Made from a soft, malleable, high-temperature metal alloy (such as nickel or a specialized alloy). When the igniter is torqued to specification, the gasket plastically deforms, or "crushes," filling the microscopic imperfections in both the igniter and the engine case to form a perfect metal-to-metal seal.
• Single-Use Component: Engineered as a mandatory single-use item. Once compressed, the gasket work-hardens and will not provide a reliable seal if reused. A new gasket is required for every igniter installation.
• Prevents Seizing: Acts as a barrier between the dissimilar metals of the igniter shell and the engine case, helping to prevent galling and seizing at extreme temperatures, which facilitates easier igniter removal during maintenance.
• Genuine OEM Part: As a genuine part specified by Textron Aviation and manufactured by Pratt & Whitney, it guarantees the correct material composition, annealing (softness), and dimensional tolerances required for a flight-critical seal.

Applications

The 3010880 is a fundamental component for engine ignition system maintenance:

• Igniter Installation: A new gasket is mandatory every time an igniter plug is installed or re-installed in the engine.
• Engine Overhaul & Hot Section Inspection: Always replaced during any maintenance action that requires the removal of the igniters.
• Preventing Combustion Leaks: The primary component responsible for preventing the escape of high-pressure, incandescent gases from the combustor.

Why Choose 3010880?

A leak from the igniter port on a turbine engine can have severe consequences, including damage to the engine case, ignition leads, and other firewall-forward components, and a significant risk of an in-flight fire. The 3010880 is the only gasket engineered and certified by the engine manufacturer to withstand this extreme environment. Using a genuine OEM part ensures the gasket is made from the correct alloy and is properly annealed to create a perfect seal. For a flight-critical seal, there is no substitute for a genuine, certified OEM part.

The sealing principle of the 3010880 crush gasket relies on plastic deformation. The soft, annealed metal is designed to have a lower yield strength than the igniter body and the engine case. When the igniter is torqued to its specified value (e.g., 240-300 lb-in), the clamping force exceeds the gasket's yield strength. This causes the gasket material to flow like a very thick fluid into the microscopic valleys and tool marks on the mating surfaces of the igniter and the engine boss. This creates a perfect, void-free metal-to-metal interface that is impervious to the high-pressure gases of combustion. This is also why the gasket is single-use; the initial compression work-hardens the metal, significantly increasing its yield strength and preventing it from properly deforming a second time.

Note: This is a single-use, flight-critical engine component. It must be replaced every time an igniter is installed. Installation must be performed by a certified A&P or AME mechanic in strict accordance with the current Pratt & Whitney Canada maintenance manual. Ensure all sealing surfaces are meticulously clean before installation.
