NTSB Probes Maintenance, Manufacturing After Jet Fire

A preliminary NTSB report found that an American Airlines Boeing 737-800 caught fire at Denver International Airport in March after maintenance errors led to incorrectly installed engine components and resulting fuel leaks. Investigators determined these issues caused abnormal engine vibrations and overheating during takeoff, prompting the flight to divert to Denver. Upon landing, a fire broke out in the right engine area, requiring emergency evacuation and resulting in 12 minor passenger injuries. Some passengers had to exit via the wings and overwing exits because an escape slide was jammed. The NTSB is now also investigating whether manufacturing problems contributed to the incident, with multiple stakeholders participating in the ongoing probe. The incident has heightened concerns over aircraft maintenance and safety oversight.
