3032096 – Pratt & Whitney Turbine Engine Igniter for PT6 Engines

Available now on the Airparts.aero Marketplace.

Overview

The Pratt & Whitney 3032096 is a genuine Original Equipment Manufacturer (OEM) turbine engine igniter, the factory-certified component for ensuring reliable ignition in specific models of the Pratt & Whitney Canada (P&WC) PT6A turboprop engine family. This flight-critical igniter is meticulously engineered to deliver a powerful, high-energy spark into the engine's combustion chamber, even under the most demanding operational conditions. Featuring a long-reach design and constructed from advanced superalloys and ceramics, the 3032096 is built to provide consistent starting performance and a long, reliable service life in the extreme environment of a turbine engine.

Key Features

• High-Energy Surface Gap Design: Utilizes a semi-conductive surface gap firing tip. This proven technology creates a massive, high-temperature spark that ensures the reliable ignition of atomized Jet-A fuel, which is essential for successful engine light-off from sea level to high altitudes.
• Optimized Long-Reach Tip: Engineered with a specific long-reach tip geometry. This design positions the spark event at the precise location within the combustor can for optimal fuel-air mixture contact and flame propagation during the start sequence, as dictated by P&WC's engine design.
• High-Purity Alumina Insulator: Features a robust ceramic insulator made from high-purity alumina. This provides exceptional dielectric strength to prevent high-voltage leakage or flashover at altitude and offers superior resistance to extreme thermal shock.
• Nickel Superalloy Shell: The igniter body is constructed from a high-strength, temperature-resistant nickel superalloy, providing excellent protection against oxidation, corrosion, and seizing in the hot section of the engine.
• Genuine Pratt & Whitney OEM Part: As the genuine OEM part, it guarantees the precise fit, material composition, and performance characteristics required by the engine's original Type Certificate. This is the ultimate assurance of quality and airworthiness.

The 3032096 igniter is a key component in a high-energy, capacitor discharge ignition system. The engine's exciter box stores a powerful electrical charge (typically 1-4 Joules) in a capacitor. During the start cycle, the exciter releases this charge as a single, high-current pulse to the igniter. The voltage is high enough to flash over the igniter's semi-conductive surface gap, creating an intensely hot, large-kernel spark. This powerful spark is essential for reliably igniting the swirling, high-velocity fuel-air mixture within the PT6A's reverse-flow, annular combustor. The igniter's design is highly resistant to carbon fouling and provides consistent performance over its entire service life.

Note: This is a high-voltage, flight-critical engine component. Installation and handling must be performed by a certified A&P mechanic in strict accordance with the current Pratt & Whitney Canada maintenance manual. The ignition system carries lethal voltages and must be fully de-energized and grounded before any maintenance is performed.
