NTSB finds fuel leak and improperly installed parts in the engine of an airliner that caught fire

A fuel leak and several improperly installed parts were found inside the engine of an American Airlines plane that caught fire after the plane landed in Denver in March, according to a report released Thursday. The preliminary findings don't identify the cause of the fire because the NTSB won't reach that conclusion until after it completes its investigation likely sometime next year. “To me, it looks like improper maintenance in the right engine leading to a fuel leak,” Guzzetti said after reading the NTSB report.
