On 20 January, an All Nippon Airways Boeing 777-300ER (registered JA787A) operated flight NH8549 between Chicago O’Hare Airport, Illinois, United States, and Tokyo Narita Airport, Japan. Shortly after take-off, the aircraft stopped climbing at 12,000 feet. The pilots squawked a 7700 distress signal and reported to air traffic control that they experienced vibrations on the aircraft’s left engine.
The pilots idled the engine, descended to 6,000 feet and entered a holding pattern to dump fuel in order to reduce its landing weight.
After the fuel dump procedure, the flight safely returned to Chicago Airport.
