https://avherald.com/h?article=526c3cee&opt=0A Jetblue Airbus A321-200, registration N955JB performing flight B6-861 from Boston,MA (USA) to San Juan (Puerto Rico) with 208 people on board, was climbing out of Boston's runway 09 when the crew levelled off at 5000 feet reporting they had an issue. Subsequently the crew advised they had an issue with the landing gear and a few minutes later declared emergency reporting they had a hydraulic failure. The aircraft entered a hold while the crew was working the related checklists and returned to Boston for a safe landing on runway 04 about 45 minutes after departure.
The FAA reported: "JetBlue Flight 861 returned safely to Boston Logan International Airport around 8:05 a.m. local time on Monday, April 21, after the crew reported a possible hydraulic issue. The Airbus A321 was headed to Luis Munoz Marin International Airport in Puerto Rico. The FAA will investigate."
A replacement A321-200 registration N999JQ is estimated to reach San Juan with a delay of about 2.5 hours.
