Engine issue prompts Delta flight to return to Tucson

“Delta flight 937 returned to Tucson shortly after takeoff following indication of a mechanical issue with the aircraft’s left engine,” a Delta statement said.

The plane landed about 1:15 p.m. without incident, and passengers are being taken on a different aircraft, the statement said. 

The Tucson Airport Authority Fire Department deployed in case of problems when the Boeing 737-900 landed. The airport remained fully operational, TAA said in a statement. 

Delta flies daily from Atlanta to Tucson and then back to Atlanta. It was the return flight to Atlanta that suffered the issue Monday.
