Passengers aboard a HiSky Europe flight to Egypt experienced a tense mid-air turnback on February 22nd 2026, when their aircraft abruptly descended from cruise altitude after cockpit indications signaled a cabin pressurization issue.
The HiSky Europe Airbus A320-200, registered YR-SUN, was operating flight H4-8711 from Henri Coandă International Airport to Hurghada International Airport with 180 passengers and six crew members on board. The aircraft had climbed to approximately Flight Level 250 when the crew detected abnormal cabin pressure indications.
As a precaution, the pilots initiated a rapid descent to 10,000 feet, the standard safe altitude in the event of pressurization concerns, allowing the aircraft to maintain a breathable cabin environment without relying on full pressurization. The crew then made the decision to return to Bucharest.
To reduce landing weight, the aircraft entered a holding pattern to burn off excess fuel before making its approach. About two and a half hours after departure, the A320 landed safely on runway 08R in Bucharest. There were no reports of injuries among passengers or crew.
According to information received by The Aviation Herald, the cause of the incident was traced to a faulty sensor that triggered the cabin pressure indications. Once on the ground, maintenance teams addressed the issue.
The aircraft departed again the following morning and completed the flight to Hurghada, arriving with an overall delay of approximately 12 hours.
While cabin pressurization warnings can be alarming, standard operating procedures and aircraft system redundancies are designed precisely for such scenarios. In this case, a swift and methodical response by the flight crew ensured a safe outcome for everyone on board.
