3014981 – Pratt & Whitney Turbine Engine Igniter for PT6 Engines

Available now on the Airparts.aero Marketplace.

Overview

The Pratt & Whitney 3014981 is a genuine Original Equipment Manufacturer (OEM) turbine engine igniter, the factory-specified component for ensuring reliable starting of the legendary Pratt & Whitney Canada (P&WC) PT6A series of turboprop engines. This flight-critical igniter is engineered to deliver a powerful, high-energy spark into the engine's combustion chamber under all operating conditions. Featuring a long-reach design and constructed from advanced superalloys and ceramics, the 3014981 is built to withstand the extreme thermal, physical, and electrical stresses of turbine engine ignition, providing the reliability that operators of PT6A-powered aircraft depend on.

Key Features

• High-Energy Surface Gap Design: Utilizes a semi-conductive surface gap firing tip. This design creates a massive, high-temperature spark kernel that ensures the reliable ignition of atomized Jet-A fuel, even in the cold, low-pressure conditions of a high-altitude relight.
• Long-Reach "J" Type Configuration: Engineered with a specific, long-reach "J" style tip. This positions the spark event precisely within the combustor can for optimal flame propagation during the start sequence, as specified by P&WC's original engine design.
• High-Purity Alumina Insulator: Features a robust ceramic insulator made from high-purity alumina. This provides exceptional dielectric strength to prevent voltage 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 corrosion and preventing 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 3014981 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, providing 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.
