Service Bulletin #0016 - Modification of ECU Standoffs [Sling TSi]

[PhilipRueker]

RELEASE DATE: 2020/03/26

EFFECTIVE DATE: 2020/03/26

SUBJECT: Modification of ECU standoffs

MODELS AFFECTED: Sling 4 TSi ready-to-fly aircraft with serial numbers up to 166s (with the exception of 147s)

COMPLIANCE TIME: At the next periodic inspection

LABOUR TIME: 0.75 Hour

DESCRIPTION: This Service Bulletin contains the instructions to inspect, and if required, modify the ECU mounting points to ensure the ECU casing is decoupled from the airframe ground. Installation requirements prohibit connection of the ECU casing to the airframe ground, so longer standoffs must be created for the casing to clear the ends of adjacent screws.

The ECU is mounted on the back of the rib located behind the instrument panel (refer to part number CF-RIB-003-C-C-5). You will find Garmin instruments mounted on the front of this rib whose mounting screws, particularly the GEA 24, could come into contact with the casing of the ECU and ground it.
