CH34723 – Champion Aerospace FAA-PMA Turbine Engine Igniter For PW206

Available now on the Airparts.aero Marketplace.

Overview

The Champion Aerospace CH34723 is a premium, FAA-PMA approved high-energy turbine engine igniter, engineered specifically for the Pratt & Whitney Canada PW200 family of modern turboshaft engines. This flight-critical component is essential for the engine's start sequence, delivering a powerful, high-temperature spark into the combustion chamber to ensure reliable light-off. Featuring Champion's advanced material science, including a high-purity ceramic insulator and a superalloy shell, the CH34723 is built to provide exceptional durability and reliable ignition performance in the extreme temperature and pressure environment of a helicopter turbine engine.

Key Features

• High-Energy Surface Gap Design: Utilizes a semi-conductor/surface gap firing tip. This design allows the high-energy (Joule) discharge from the exciter to ionize a path across the tip's surface, resulting in a massive, high-current plasma arc that is highly effective at igniting atomized jet fuel.
• Advanced Alumina Ceramic Insulator: The core of the igniter is a high-purity alumina ceramic insulator, which provides superior dielectric strength to prevent high-voltage flashover at altitude and offers exceptional resistance to the extreme thermal shock of rapid engine starts and shutdowns.
• High-Temperature Superalloy Construction: The body and shell of the igniter are machined from a high-strength, nickel-based superalloy, providing robust resistance to the intense temperatures and corrosive, high-pressure gas environment of the PW200's combustor section.
• Hermetic Sealing: Incorporates advanced glass and metal hermetic sealing to prevent the leakage of high-pressure combustion gases past the igniter. This is critical for protecting the ignition lead and exciter from damage and ensuring optimal engine performance.
• FAA-PMA Certified: As a certified FAA-PMA part from the world leader in aviation ignition, it has been rigorously tested to meet or exceed the performance, safety, and quality standards of the original engine manufacturer's part, making it a fully airworthy and cost-effective solution.

Applications

The CH34723 has a singular, flight-critical application:

• Engine Start Ignition: Delivers the electrical spark from the ignition system directly into the engine's reverse-flow combustion chamber to initiate light-off. Two igniters are used per engine for full redundancy.
• Scheduled Maintenance Item: A life-limited component that must be inspected and replaced at specified service intervals to ensure continued ignition system reliability and prevent start-related issues.

Why Choose CH34723?

The ability to reliably start an engine is critical for every flight, and absolutely essential for helicopter missions such as HEMS (Helicopter Emergency Medical Services) and law enforcement where rapid dispatch is required. The Champion CH34723 is engineered with the material science and robust design necessary to perform reliably in the violent environment of a turbine engine combustor. Choosing a genuine Champion Aerospace PMA igniter guarantees you are installing a component with a known service life, certified performance, and the advanced features required to ensure reliable starts, every time.

The CH34723 operates as a surface-gap igniter within a high-energy capacitor discharge ignition system. An exciter box converts the helicopter's DC power into high-voltage DC to charge a storage capacitor. Upon command, this capacitor discharges its entire energy load (measured in Joules) through a specialized ignition lead to the CH34723 igniter. The igniter's surface-gap design features a low-resistance semiconductor material between the electrodes. The high-voltage pulse ionizes this material, creating a path for a very high-current, short-duration plasma arc. This arc is significantly hotter and more powerful than a conventional spark, ensuring it can reliably ignite the high-velocity, atomized fuel spray within the combustor, even under the adverse conditions of a high-altitude relight attempt.

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