While in cruise flight at flight level FL430, the aircraft entered a forced descent due to a pressurization failure. The flight crew decided to divert to Geneva Airport (LSGG).
The information available to the investigation indicates that the alarm for the pressurization issue likely stemmed from a fault in one of the two pressurization controllers, rather than an actual depressurization. When the pressurization problem alarm occurred, the crew promptly reacted by declaring a distress situation in order to initiate an emergency descent without delay. Both pilots donned oxygen masks and adhered to the operational limits of the aircraft. Thus, the lives of the five occupants of the aircraft were never in danger. The decision to divert to Geneva was appropriate, and cooperation with the control services proceeded without issue, taking into account the topography of the French Alps.
