Boeing’s updates to its 787 Dreamliner jet mitigate issues identified by the U.S. Federal Aviation Administration that it has identified as “threat zones”.

In a significant development, the U.S. Federal Aviation Administration stated, it was mandating new flight control software and parts to Boeing Co’s 787 Dreamliner in order to address an unsafe operating condition of certain products on the plane.

The FAA’s airworthiness directive to Boeing and other airplane operators require that they make compulsory changes to certain “threat zones” areas that are susceptible to potential damages.

In its service bulletins in 2017 and early 2018 Boeing has addressed these “threat zones”, which includes the 787’s tire and wheel, said Boeing.

“This issue has been long since resolved with system improvements that have been incorporated into production for all 787 models,” said Boeing.

According to the FAA, damage to the 787’s tire and wheel “threat zones” could result in the loss of braking and steering power on the ground at certain speeds.

TO remedy the threat, the FAA requires that airplane makers install a pressure-operated check valve as well as a new flight control software.

The work has been completed on existing 787s and incorporated into the manufacturing process, said Boeing.
