Alaska Airlines 787 Emergency at Rome: AS181 Returns After Engine Vibration

An Alaska Airlines Boeing 787-9 declared an in-flight emergency over the Atlantic Ocean July 19 after the crew of Flight AS181 reported engine vibration and a possible mechanical issue roughly two hours after departing Rome Fiumicino (LIRF) bound for Seattle-Tacoma (KSEA).

Flight tracking data shows the aircraft executed a sharp U-turn over the southeastern United Kingdom before orbiting over mainland France to conduct a fuel-dump procedure and reach a safe landing weight. The Boeing 787-9 touched down safely on Runway 16R at Fiumicino at approximately 21:15 CEST with no injuries reported among passengers or crew.

Official Response and Maintenance

Alaska Airlines confirmed the crew declared the emergency to secure priority handling from air traffic control — standard procedure for in-flight mechanical events. Following a post-landing inspection, the airline determined the aircraft required further maintenance and canceled the flight; affected passengers were rebooked on alternative itineraries. No regulatory bulletins from the FAA or EASA have been issued. Technical teams are examining the aircraft to determine the precise cause of the vibration.
