Overview

• On March 13, an American Airlines Boeing 737-800 bound for Dallas diverted to Denver International Airport after the crew reported high engine vibrations and the right engine caught fire upon arriving at the gate.
• Investigators discovered one engine part installed in the wrong direction and a loosely fastened fuel fitting that allowed fuel to leak, with streaks visible on the engine during taxi.
• Flight attendants initiated an evacuation when smoke filled the cabin, and 12 people sustained minor injuries as passengers used multiple exits, though a rear escape slide jammed and a door failed to open.
• Gate workers extinguished the fire within a minute before firefighters arrived, limiting damage to the aircraft that carried 172 passengers and six crew members.
• The NTSB investigation remains ongoing with a final report due next year, and officials may issue safety recommendations to strengthen maintenance protocols.
