An American Airlines flight out of DFW International Airport had to make an emergency landing in Los Angeles after a reported mechanical issue on a Boeing 777 airplane.

On Wednesday night, American flight 345 landed at 8:51 p.m. Pacific Time, according to flight data tracker FlightAware . According to CBS News , the Fort Worth-based airline said the pilot reported a possible mechanical issue before landing. It’s unclear what the issue was, however, some early reports suspected a blown tire.

Major U.S. airlines all over have recently had some situations with mechanical issues on aircraft.

Just this month, a United Airlines flight aircraft ran off the taxiway into a grassy area after landing in Houston. That was only a day after another United flight had a mid-air loss of a tire on a Boeing 777.

Of course, the most notable issue on an airplane this year was January’s Boeing 737 Max 9 blowout that left a gaping hole in the side of an Alaska Airlines fuselage . Since then, major airlines like American and Southwest Airlines have called on the planemaker to “become a better company.”
