Executive Summary:While cruising north of Paris at FL 370, the aircraft experienced a pressurisation failure. After declaring a “MAYDAY”, the crew carried out an emergency descent to FL 100. Diverting to Charles de Gaulle (LFPG) Paris, the aircraft landed at 14.20 hrs without further incident. There were no reported injuries to crew or passengers.

(b) Causes
A combination of factors, including failure of the CPC in AUTO-mode and a defective outflow valve, coupled with an intermittent supply pack fault could have given rise to this loss of pressurisation.
