3074541-4 IGNITER

Item description from the seller

Aircraft turbine engine igniter plug engineered to deliver the high-energy spark required for reliable engine start and continuous-ignition operation. This OEM-grade component is a critical wear item in the engine ignition system and is supplied as a direct-replacement unit for scheduled service or AOG recovery. Overview The 3074541-4 Igniter is the high-voltage discharge component that converts electrical energy from the engine's exciter box into the spark that initiates combustion in the engine's combustion chamber. As a consumable wear item, igniters degrade over time through electrode erosion and require periodic replacement per the engine manufacturer's maintenance program. Key Features High-energy discharge — engineered to fire reliably across the full envelope of altitude, temperature, and fuel conditions Erosion-resistant electrodes — extended service life under repeated high-voltage discharge cycles Sealed construction — protects internal components from combustion byproducts, moisture, and contamination Precision-machined shell — proper torque seating and gas-tight seal at the combustor port OEM specification — meets original manufacturer materials, dimensional, and electrical requirements Typical Applications Turbine engine ignition systems (turbojet, turbofan, turboprop, turboshaft, APU) Engine start ignition circuits Continuous ignition for icing, takeoff, and turbulent-air operations Direct replacement for time-expired or eroded igniter plugs Confirm specific engine model and position applicability against the applicable Engine Manual, IPC, or maintenance program before installation.
