Boeing's new 787 won't fly until November or December

Boeing Co.'s new 787 jetliner will not begin flight testing until months later than originally planned, the head of the company's commercial airplanes unit said today.

The testing won't begin until mid-November or mid-December because it's taking longer than anticipated to get the first plane ready, said Scott Carson, chief executive of Boeing Commercial Airplanes.

Boeing initially aimed to begin flight testing within a monthlong window beginning in late August, but early last month acknowledged first flight might not happen until at least October.

The 787 is the first large commercial jetliner being made mostly from composites, which Boeing has promised will make the plane more fuel efficient and cheaper to maintain because carbon fiber-reinforced plastics are lighter and more durable than aluminum.

On Wednesday, Carson said the first flight will be pushed well into the fall because of delays in completing assembly of the first plane and in finalizing flight-control software.

Even so, Carson said the 787 remains on track to be delivered to its first customer, Japan's All Nippon Airways, next May.

Boeing unveiled its first midsize, long-haul 787 amid much fanfare in early July, but has spent the past several weeks working to get that plane ready for its maiden flight.

The 787's flight-test program will be much more condensed than that of Boeing's last all-new jet, the 777, which went through about 11 months of flight testing before airlines first started flying it in 1995.

To get the airplane certified on time, Mike Bair, vice president and general manager of the 787 program, has said the company plans to fly six fight-test 787s at higher rates than it's done with previous planes. Two other planes will undergo static and fatigue tests.
