A Getjet Airlines Malta Airbus A320-200 on behalf of Norwegian, registration 9H-EMU performing flight D8-4311 from Stockholm (Sweden) to Paris Charles de Gaulle (France), was on an RNP approach to CDG's runway 27R, however, with an erroneous Altimeter setting, instead of QNH 1001 hPa the crew had select 1011hPa). The approach was thus performed below the glide path and eventually triggered a Minimum Safe Altitude Warning (MSAW) at the controller's desk. In response the crew initiated a go around at low height, without having acquired visual contact with the ground, and positioned for another approach. The second approach was also performed below the glideslope, the crew however acquired visual contact, corrected their trajectory and landed without further incident about 16 minutes after the go around.

The French BEA rated the occurrence a serious incident (category Controlled Flight Into Terrain) and opened an investigation.

On Jul 11th 2022 the BEA released their preliminary report in French (subsequently also their preliminary report in English) reporting that for the first approach the approach controller provided an erroneous QNH (1011 hPa instead of 1001 hPa) causing the aircraft to continue 260 feet below the correct altitudes. Although the crew read back 1011hPA several times and other aircraft were given the correct QNH of 1001 hPa, the error was not picked up by ATC or by the crew. The MSAW alarm went off and the crew initiated a go around about 1nm before the runway threshold, the aircraft reached a minimum of 405 feet according to QNH 1001hPa (679 feet QNH 1011 hPa), the radio altimeter indicated 6 feet above ground level. However, no TAWS alerts were recorded during the approach. The controller cleared the aircraft: "turn right heading 360, climb to 5000 feet, 1001", the crew read back: "360 and climb to 5000, 1011" which was not picked up by the controller. The controller was relieved and another controller took this position over. However, the (correct) QNH was not provided to the crew or any other crew until after the aircraft landed. Still with the erroneous QNH the aircraft positioned for another approach. 3.1nm before the runway threshold a MSAW alarm activated again, the controller informed the crew who did not understand the reason for the MSAW and reported they were visual - in later testimony they reported they saw the PAPIs, one white, one pink, two red, maybe three red, however, definitely not 4 red. They applied a pitch up to correct their trajectory and continued for a landing without further incident.
