The regulator connector bracket assemblies are not a part of the Engine Type Design. The regulator connector bracket assemblies have been tested and released by BRP-Rotax, but they are not certified. The certification of the connector bracket assemblies is the responsibility of the aircraft manufacturer and must be carried out jointly with the aircraft.
Concurrent ASB/SB/SI and SL
In addition to this Service Instruction - PAC the following Service Instruction should be considered: SI-915 i-006, Introduction of a new connector for regulator B for ROTAX® Engine Type 912 i, 915 i A and 915 i B (Series)“, current issue. In the course of continuous development and standardization, regulator connector brackets have been introduced as an optional extra part. Connector bracket part no. 951983 is designed to retain DEUTSCH® connectors, while connector bracket part no. 951981 is designed to retain Amphenol® connectors.
