Investigating agency: AAIU
Narrative:
The aircraft was on a scheduled passenger flight from Birmingham Airport (EGBB), United Kingdom, to Cork Airport (EICK), Ireland. The flight was uneventful until just before the aircraft began its descent into Cork, at which point the Flight Crew received a Master Caution, triggered by two electrical faults. This was followed by a Master Warning associated with electrical smoke and by the sight and smell of smoke in the cockpit. The Flight Crew donned their oxygen masks, declared an emergency (Mayday) to Air Traffic Control (ATC), and carried out the SMOKE Checklist memory actions. Non-normal checklists associated with Smoke, Electrical Smoke, and associated electrical failures were also completed, including the Manual Gear Extension checklist. The smoke cleared and the aircraft landed normally.
There were no injuries.
Examination of the number 2 static inverter showed that a C602 capacitor within the unit had failed in a manner that resulted in electrical smoke being emitted from the unit. This smoke entered the avionics ventilation air flow and was detected by the avionics smoke detector installed in the avionics extract air duct, triggering the associated Master Warnings. The smoke also entered the cockpit and forward cabin, where it was noticed by the Flight Crew and No. 2 CCM.

Probable Cause: "Failure of the C602 (1-001-0306-0136) capacitor within the number two static inverter."
