Paris, France: Malaysia Airlines flight MH21, operating a scheduled long-haul service from Paris Charles de Gaulle Airport (CDG) to Kuala Lumpur International Airport (KUL), was forced to turn back and land safely in Paris on 7 January 2026 after the flight crew detected an anomaly in the aircraft’s guidance systems shortly after departure.
The Airbus A350-941, registered 9M-MAB, departed CDG at 11:55 a.m. local time, approximately 45 minutes behind its scheduled departure, reportedly due to ongoing snowfall and reduced airport operational capacity at Paris.
Shortly after take-off and while climbing through around 4,572 metres (15,000 feet) over central French airspace, the flight crew identified an irregularity affecting the aircraft’s guidance system, a critical suite of avionics that integrates autopilot, flight management and navigation functions to determine and maintain the planned flight path.
Upon detecting the issue, pilots activated the aircraft’s emergency transponder code “7700”, the universal aviation signal indicating a general emergency, and immediately communicated with French air traffic controllers to request priority handling and clearance to return to CDG.
The A350 remained under controlled flight while returning to Paris and landed safely at 3:36 p.m. local time. Emergency response teams were positioned on standby at the airport as a precaution, though no injuries or further technical complications were reported.
Malaysia Airlines and the Malaysia Aviation Group (MAG) confirmed in a statement that the aircraft’s return was a precautionary measure taken in line with established safety procedures for technical irregularities, and not in response to any imminent danger.
Passengers disembarked normally. Those affected were either reaccommodated on alternative carriers where possible or provided with hotel accommodations near the airport while awaiting onward travel arrangements. A replacement service, designated MH21D, was scheduled to depart from CDG later on 8 January.
In its official communication, Malaysia Airlines expressed regret for the disruption to travel plans and reiterated that flight safety remains the airline’s overriding priority. The carrier confirmed that the aircraft will undergo detailed technical checks before it is permitted to operate further services.
