There is a new software update available that will enhance the engine core speed (N2) margin and assist in meeting new production requirements.
A service bulletin has been issued to allow Honeywell personnel to upload the new software and re-identify each ECU installed. Although the G280 fleet is growing, Honeywell can capture all ECUs and perform the software update in the field without returning the units to the supplier. Going forward, new production engines will be delivered with the new software already installed.
Refer to Service Bulletin: AS907-76-9016 – Engine Controls – Power Controls – Install Software Version 90721G0201 in Electronic Control Unit (ECU).
