Fire warning: Frontier A321neo landed back in Denver
The Airbus A321neo with registration N701FR, operated by the low-cost airline Frontier Airlines, had to make a return landing shortly after takeoff in Denver on January 25, 2024. The pilots received a warning message that an engine fire had broken out. As suddenly as the warning appeared, it disappeared again "as if by magic". Nevertheless, the captain did not take any safety risks and requested a return landing at Denver Airport. This was successfully completed. It turned out that no fire had broken out. The airline has arranged for the N701FR to be thoroughly checked by technicians as a precautionary measure. Frontier Airlines Flight 4635 was scheduled to fly from Denver to Phoenix on January 25, 2024 with this Airbus A321neo. After the return landing, the passengers were flown to their destination on a replacement aircraft.
