Preliminary investigation was undertaken into a category 4 occurrence where the incident featured an avionics smoke warning. There was no evidence of smoke reported by the flight or cabin crew. Subsequent inspection by maintenance personnel showed no evidence of smoke. The reason for the spurious warning was attributed to dust-disturbance that may have activated the smoke sensor.

Status: Downgraded the occurrence and investigation discontinued.
