• An American Airlines Boeing 737 made an emergency landing on Thanksgiving weekend.
• The FAA said the crew reported a “possible electrical issue.”
• An airline spokesman said the ad was later confirmed to be false.

An American Airlines jet was forced to make an emergency landing on Sunday after the crew reported a “possible electrical issue.”

The 14-year-old Boeing 737 was on Flight 1047 from Chicago O’Hare to Las Vegas. Data from Flightradar24 shows it flew for about half an hour before returning to Chicago.

“American Airlines Flight 1047 returned safely to Chicago O’Hare International Airport at approximately 9:45 a.m. local time on Sunday, December 1, after the crew reported a possible electrical issue,” Federal said in a statement Aviation Administration.

The FAA will investigate the incident, she added.

The Aviation Herald, which first reported the incident, said the crew reported the autopilot and autothrottle were turned off, a takeoff configuration warning horn and door lights were activated.

“An indicator light identified a possible mechanical issue, which upon inspection was determined to be false,” an American Airlines spokesperson told Business Insider.

According to Flightradar24, the same 737 flew to San Francisco later in the day.

Sunday’s incident occurred over Thanksgiving weekend, one of the busiest travel times in the United States.

From Sunday, November 24, through Thanksgiving, the FAA documented a record 232,000 flights across the United States.

American Airlines said last month that it expects to carry 8.3 million people on more than 77,000 flights – with Sunday being its busiest day.

The passengers later flew back to Las Vegas on a replacement plane, an airline spokesperson told USA Today.

The incident comes eight days after an American Airlines passenger was hospitalized after a 777 between Brazil and Miami encountered turbulence. It was a four hour flight to nowhere.
