A Delta Air Lines Airbus A330-300 bound for Atlanta was forced to declare an emergency and return to Sao Paulo’s Guarulhos International Airport late on Sunday night after its left engine erupted in flames seconds after takeoff, triggering scenes of terror inside the cabin and temporarily shutting down one of South America’s busiest aviation hubs.
A Night of Fear Above Guarulhos
The aircraft, carrying 272 passengers and 14 crew members, departed Guarulhos International Airport and suffered a mechanical issue with its left engine shortly after liftoff, sending flames and sparks shooting from beneath the wing. The incident occurred at 23:49 local time on March 29. The aircraft had climbed only a couple of hundred feet when the engine failure occurred, forcing the crew to turn back immediately.
Air traffic control recordings captured the moment the situation became critical. The controller radioed, “Delta, you have fire on your wings,” to which the pilot confirmed the emergency and stated the aircraft needed to return. The exchange reflected a swift and coordinated response between the flight deck and ground teams.
According to reports, the aircraft had climbed to approximately 4,500 feet when the engine failure occurred. Videos posted to social media showed flames visibly shooting from the plane as it banked over the urban sprawl of Sao Paulo and circled back toward the airport.
Panic in the Cabin
For the passengers seated on board, the experience was harrowing. Video footage of the flight taking off shows loud bangs and several large flashes sparking on the plane’s left side seconds after the jet’s wheels lifted off the ground. Pieces of scorched material can be seen falling to the ground, causing a small brush fire next to the runway.
Passengers described feeling despair in the moments following the blasts. In a video from inside the cabin posted on X, travellers can be heard screaming and praying. “I felt a lot of panic, just panic. Fear, fear of dying, you see the plane catching fire, you know, what are you going to think?” passenger Renata Liehy said in an interview with Brazilian broadcaster Globo.
Safe Landing, Disrupted Airport
Despite the alarming circumstances, the crew brought the aircraft down safely. The plane landed safely and no injuries were reported. Passengers were bused back to the terminal at Guarulhos International Airport.
The landing, however, came with an additional complication. Runway 10R/28L was closed for maintenance at the time of the incident, creating a bottleneck. The A330 had to land on runway 10L, the same runway from which it had taken off, as it was the airport’s only active runway available. Metallic debris on the runway and the fire forced a temporary suspension of airport operations, disrupting schedules for several international departures.
Delta issued a formal statement acknowledging the incident: “The Airbus A330-300 landed safely and was met by ARFF. The safety of our customers and crew is our highest priority. We apologise to our customers for this delay in their travels.”
A 19-Year-Old Aircraft Under Scrutiny
An investigation into the mechanical failure is expected from Brazil’s aviation authority, CENIPA, and possibly the U.S. National Transportation Safety Board. Possible causes under examination include foreign object debris ingestion or a bird strike, as another aircraft in the area had reportedly flagged a bird sighting around the time of the incident.
The Airbus A330-300 involved in the incident is 19 years old, having first entered service with Northwest Airlines in 2006. Delta Air Lines acquired the aircraft in December 2009 following Northwest’s merger with Delta, and it has continued operating under its original registration ever since.
A Pattern Raising Concern
Sunday’s emergency does not stand in isolation. The Guarulhos incident adds to a series of engine-related emergencies involving Delta aircraft in recent months. In February 2026, a Delta Boeing 737-900 lost its left engine during takeoff from Savannah, Georgia, igniting a grass fire along the taxiway. In July 2025, a Delta Boeing 767-400 suffered an engine fire after takeoff from Los Angeles, requiring an emergency return though with no injuries reported.
The recurrence of engine-related incidents has renewed scrutiny of Delta’s maintenance protocols, particularly around its ageing widebody fleet. While aviation remains one of the safest forms of transport by any statistical measure, three engine failures in the span of eight months will inevitably invite closer examination from both regulators and the travelling public. Delta has cancelled flight DL104 and is in the process of rebooking affected passengers on alternative services as the aircraft undergoes a full technical inspection.
