The corporate stated a big variety of its A320 fleet, encompassing about 6,000 jets in whole, could also be impacted by the required repair, based on an announcement despatched by the European planemaker on Friday.
“Airbus acknowledges these suggestions will result in operational disruptions to passengers and prospects,” the corporate stated.
The advisory follows an incident on Oct. 30 involving a Jetblue plane that was flying from Cancun to Newark, New Jersey, that suffered a pc glitch that resulted in a sudden, sudden downward pitch with out pilot enter.
