A UPS cargo plane, which crashed in Louisville on Tuesday, had been in service for 34 years and was recently taken out of operation for over a month to address serious fuel tank issues, a report indicates.

FAA maintenance records, examined by The Wall Street Journal, reveal that the MD-11 aircraft was grounded in San Antonio from September 3 to October 18. During this period, it underwent essential repairs to fix a crack in its fuel tank before resuming flights.

Tragically, the aircraft lost its engine shortly after takeoff from Louisville’s Muhammad Ali International Airport, resulting in a catastrophic nosedive and fiery crash that claimed the lives of at least 12 people, including a child, according to officials.

The accident ignited a massive fireball that engulfed the large plane and extended to nearby businesses, as shown in dramatic footage.

At the time of the crash, the jet, with three UPS employees onboard, was transporting approximately 50,000 gallons of fuel.
