New Service Letter from Jabiru JSL015-1 regarding the 2200 engine.
Background: In July 2014 Jabiru Aircraft released a notification to owners of certain 2200 engines regarding a potential issue affecting their ignition systems.
The issue can occur when the housing for the spring-loaded central carbon brush rubs against the rotor as it turns. Over time in service the friction in this area can “weld” the rotor to the cap and in some cases has led to a failure of the rotor and then of the ignition.
