A Delta Air Lines Airbus A320‑200 operating flight DL1676 from San Antonio to Atlanta made a precautionary return on 3 February 2026 after the crew received an engine fire indication shortly after departure.
The aircraft, registered N356NW, landed safely back at San Antonio International Airport (SAT) approximately 25 minutes after takeoff, with no injuries reported among the 143 passengers and crew.
The Incident Onboard The Delta Flight in San Antonio…
DL1676 departed San Antonio’s runway 22 late morning, beginning what should have been a routine sector to Atlanta.
As the aircraft climbed through its initial departure phase, the flight crew received a fire indication for the No. 2 CFM56 engine.
According to the incident report, the crew declared a Mayday, reduced the affected engine to idle, and requested an immediate return to SAT.
Notably, the engine was not shut down, suggesting the crew assessed the indication as non‑escalating but still serious enough to warrant a precautionary landing.
The aircraft touched down safely on the same runway from which it had departed, with emergency services positioned but ultimately not required.
The FAA later confirmed the safe return and announced an investigation into the cause of the engine issue.
Aircraft Status and Operational Context
Following the incident, N356NW remained on the ground in San Antonio for roughly 26 hours before being ferried to Atlanta.
As of the latest update, the aircraft had not yet returned to commercial service, pending further inspection and maintenance actions.
Flight‑tracking data shows that in the days leading up to the incident, the aircraft had been operating a typical mix of domestic routes, including rotations between Atlanta, Washington, Dallas, Appleton, and San Antonio.
Its final completed flight before the event was DL1408 from San Antonio to Atlanta on 27 January, part of a consistent operational pattern across the south-eastern and midwestern United States.
About the Airframe Involved in the Incident in San Antonio: N356NW
The aircraft involved, Airbus A320‑212 MSN 818, is a 27.8‑year‑old airframe originally delivered to Northwest Airlines in May 1998 before joining Delta’s fleet following the 2008 merger.
It has undergone several cabin configuration changes during its service life, most recently shifting to a C16Y141 layout in 2017.
The aircraft has also experienced periods of storage, including a multi‑month grounding at San Bernardino (SBD) during 2020.
Despite its age, the A320 family remains a backbone of Delta’s narrow‑body fleet, and older airframes like N356NW continue to operate safely thanks to rigorous maintenance cycles and ongoing system upgrades.
Investigation and Next Steps
The FAA’s investigation will focus on the cause of the fire indication—whether it stemmed from a genuine overheat condition, a sensor malfunction, or another technical anomaly.
Engine fire indications are designed to be conservative, and while false alarms are not uncommon, each event is treated with full procedural seriousness.
Delta has not reported any further issues with similar aircraft or engines, and passengers were re‑accommodated on later flights.
