São Paulo, Brazil: A Delta Air Lines Airbus A330-300 operating a scheduled international service from São Paulo-Guarulhos International Airport (GRU) to Atlanta was forced to return shortly after takeoff on Sunday night after the crew detected a serious engine malfunction, with fire visible from the wing, prompting an emergency declaration and rapid return to the departure airport.
The aircraft, operating as Delta Flight DL104, departed São Paulo with approximately 272 passengers and 14 crew members onboard. The flight had only been airborne for a few minutes when the crew reported abnormal engine performance during initial climb.
Shortly after takeoff, the flight crew identified a critical engine issue involving the left engine, with passengers reporting loud noises, vibrations, and visible disturbances near the wing area. The aircraft remained under control as the pilots initiated standard emergency procedures and coordinated an immediate return to São Paulo-Guarulhos Airport.
Air traffic control facilitated priority handling of the aircraft’s return, while emergency response teams were placed on standby in preparation for landing. The aircraft executed a rapid turnaround and returned to the departure airport within minutes of takeoff.
The Airbus A330 landed safely on Runway 10L at São Paulo-Guarulhos Airport approximately 8-10 minutes after departure. Airport rescue and firefighting services were deployed as a precaution and escorted the aircraft after touchdown. The aircraft came to a full stop without any runway excursion or structural failure.
All passengers and crew were safely evacuated following landing. No injuries or fatalities were reported, according to initial confirmations from authorities and airline statements cited by multiple news organisations.
Delta Air Lines confirmed the incident and stated that the aircraft experienced a mechanical issue shortly after departure, requiring an immediate return to São Paulo as a precautionary measure. The airline added that all passengers and crew were safe, and that it had initiated rebooking and care arrangements for affected travellers.
The airline further stated that the aircraft has been removed from service pending a detailed technical inspection and maintenance checks. Delta also confirmed full cooperation with aviation authorities as part of the ongoing investigation.
The aircraft involved is an Airbus A330-300 used in Delta’s long-haul international operations. The exact cause of the engine failure has not yet been confirmed. Aviation authorities in Brazil are expected to lead the investigation, with possible coordination with the US National Transportation Safety Board (NTSB). Investigators will examine engine data, maintenance records, and potential external factors including foreign object ingestion or mechanical failure.
