Kaohsiung, Taiwan: Cathay Pacific Airways flight CX449, bound for Hong Kong from Kaohsiung International Airport in Taiwan, was forced to return to its departure airport on Sunday morning after an engine system alert indicated a possible technical issue, airline and aviation sources confirmed.
The Airbus A321neo, scheduled to depart at 7:45 am local time with about 200 passengers on board, took off as planned but turned back shortly after take-off when cockpit instruments showed an abnormal reading related to one of the engines. The aircraft landed safely back in Kaohsiung at around 8:26 am to 8:49 am under standard safety procedures, according to reports.
Preliminary inspections by technical teams at Kaohsiung indicated that a lubricant (engine oil) leak in one engine likely caused the pressure anomaly and triggered the warning that prompted the turn-back. Maintenance crews estimated around two hours would be needed to clear any spilled oil and carry out targeted system checks before deciding on the aircraft’s next steps.
Cathay Pacific described the incident only as a “technical issue” in its official comment, without confirming specific engine fault details in its public statement, while emphasising that safety considerations guided the decision to return. Taiwanese media reports also referenced the engine oil leak as the apparent cause.
All passengers disembarked normally after the aircraft returned to Kaohsiung. Cathay Pacific ground staff assisted travellers by rebooking them onto alternative flights to Hong Kong later the same day. Ground teams reportedly provided meal vouchers and refreshments and worked to restore schedule stability by deploying aircraft with higher seating capacity where possible.
The airline also issued an apology to affected customers and thanked them for their patience while disruptions were managed.
The A321neo involved in the flight has been grounded at Kaohsiung while further detailed inspections and any necessary engineering work are carried out. Safety officials and airline engineers are continuing to examine the affected engine to determine the full technical cause of the pressure and oil leak anomaly.
Cathay Pacific said the crew followed standard procedures in responding to the alert, underlining the airline’s commitment to operational safety.
