8 Page DESCRIPTION The 206ER-100 Engine Relight System is entirely an electrical system that automatically initiates the Ignition Exciter Assembly by sensing a drop in engine RPM in the event of an engine shut down. The Ignition Exciter Assembly is activated when the Power Turbine Tach Generator drops below 96% and is again disabled if the gas producer drops below 55%. The Engine Relight System has two separate configurations, denoted as the 1 Installation and 2 Installation. The 206ER Installation is intended to be a permanent installation with the Engine Relight Sensor Assembly mounted inside of the instrument console and the control switch and indicator light mounted directly on the instrument panel. This system is comprised of the following: a. 206ER Electrical Installation b. 206ER Electrical Installation The 206ER Installation is designed for easy installation and removal, with the individual components mounted in single box. This box contains the Engine Relight Sensor Assembly, control switch, and indicator light and is mounted on the enter console of the aircraft. This system is comprised of the following: a. 206ER-350 Electrical Installation (-2 Installation) System specifications are as follows: WEIGHT (206ER-100-1): 0.6 Lbs. WEIGHT (206ER-100-2): 2.8 Lbs. ELECTRICAL POWERED REQUIRED (-1/-2): Volts

9 Page INSPECTION AND MAINTENANCE It is the objective of this inspection and maintenance procedure to ensure that component installations are secure and that the electrical system is airworthy. Table I, TROUBLESHOOTING PROCEDURE, refers to the most likely problems which may be encountered, and outlines the appropriate corrective actions. All loose and/or replaced fasteners should be torqued per the requirements outlined in Appendix A. 2.1 Electrical Installation (206ER-300-1, 206ER-300-2, 206ER-350-1) Inspect all electrical wiring for insulation damage and chafing. Verify integrity of wiring restraints. Replace cable assemblies as necessary Check switch and Ignition Exciter Assembly by placing the switch in the test position and listening for the activation of the Ignition Exciter Assembly Verify warning light, press to test for correct operation. (This is for 206ER and 206ER configurations only) Bring the aircraft to flight idle (Ground Idle), place the switch in the arm position. The Engine Relight Caution Light should turn on. 3.0 COMPONENT REMOVAL AND REPLACEMENT 3.1 Electrical Component Removal Insure that the power is off to the Engine Relight Breaker Disconnect cable from components Disconnect fasteners from component or cable. 3.2 Electrical Component Installation Insure that the power is off to the Engine Relight Breaker Connect cable to component Connect fasteners to component or cable.

31 Page B-1 ANNUAL/100 HOUR INSPECTION CHECKLIST Inspection Comment Initials Verify system operation by placing the switch in the test position and listening for activation of the Ignition Exciter Assembly. Verify system operation by Arming the system when the aircraft is at flight idle (Ground Idle). Caution light should activate. See the applicable Bell Model Maintenance Manual for Instructions to verify operation of the EXCITER ASSEMBLY and the IGNITER ASSEMBLY. Verify that the warning light activates and press to test function works.
