ICAO素材:Hydraulic Fluctuation

On September 22, 2021, An American Airlines Boeing 737-800, performing flight American 1444 from New York JFK to Charlotte (USA) with 120 people on board, was climbing out of New York's runway 22R when the crew requested to enter a hold to troubleshoot a problem with the hydraulic system A, which was showing fluctuations. The crew accepted an offer to level off at 5000 feet, worked the checklists, decided to return to JFK and declared Emergency. The aircraft landed safely back on runway 22L, vacated the runway and stopped clear of the runway requesting emergency services to check whether there were any hydraulic leaks around the aircraft. Emergency services reported seeing no leaks and followed the aircraft to the apron.
