UPDATE 2-U.S. FAA directive enshrines changes to Boeing 787 Dreamliner

The U.S. Federal Aviation Administration on Wednesday said it was mandating new flight control software and parts to Boeing Co's 787 Dreamliner to address what it called an unsafe operating condition of certain products on the plane. The FAA's airworthiness directive to plane operators makes compulsory changes Boeing outlined in service bulletins in 2017 and early 2018 for certain areas in 787's tire and wheel "threat zones" that may be susceptible to damage, the company said. Boeing's carbon composite 787, of which there are nearly 800 in service, mostly competes with European rival Airbus' A350.
