At approximately 1944 Coordinated Universal Time on 23 July 2007, an Airbus Industrie A330- 202 aircraft, registered VH-EBE, was about 4 hours into its flight from Bangkok, Thailand to Melbourne, Australia, when the left (No-1) engine had an uncommanded shutdown.

The flight crew attempted unsuccessfully to restart the engine and subsequently diverted to Denpasar Airport, Indonesia. The operator's maintenance staff inspected the aircraft and performed a series of tests and examinations, which revealed that the engine electronic control unit (ECU) for the No-1 engine had malfunctioned.

The defective ECU was sent to the component manufacturer for a detailed inspection. That inspection found a short circuit in the input output module (IOM) circuit board that developed from a microscopic air void in the insulation compound of the circuit board layers.

As a result of this incident, the aircraft operator replaced the ECUs in a number of aircraft, and the board manufacturer amended its production standards and procedures.
