Norwegian Air Sweden flight D84311, an Airbus A320-233, nearly struck the ground on approach to Paris-Charles de Gaulle Airport in France when it descended to 6 feet above ground level during a go-around.

The flight was operated by AirHub Airlines on behalf of Norwegian Air Sweden and had departed Stockholm-Arlanda Airport (ARN), bound for Paris-CDG. Weather at Paris-Charles de Gaulle was poor due to Cumulonimbus (CB) clouds with rain showers, causing limited visibility.
The flight was cleared for an Required Navigation Performance (RNP) approach to runway 27R. The lateral guidance in this RNP approach relied on satellite (GNSS) positioning. Vertical guidance was based on the aircraft barometric altitude.

During descent, the Intermediate (ITM) controller at CDG twice reported the QNH altimeter pressure setting to be 1011 instead of 1001 mb.
The controller also reported this incorrect setting to an easyJet flight, but that crew read back the correct value (1001).
The ITM instructed later gave instructions to an Air France flight, in French, with the correct QNH 1001.
The flight crew was subsequently cleared to land by the Tower controller while descending around 280 ft below the descent profile.
The ground Minimum Safe Altitude Warning (MSAW) was then triggered and the controller radioed the crew. The crew stated they did not hear this radio-communication. However, the crew initiated a go-around. The minimum radio-altimeter height was recorded at 6 ft above the ground, at 0.8 NM from the runway threshold.
A second approach was flown based on the same erroneous QNH, again resulting in an MSAW warning with ATC. This time the flight crew were able to see the runway and PAPI’s, corrected the flight path on final and then landed without further incident.
