“Firm configuration means the airplane’s structural, propulsion and systems architectures are defined and not changing,” said Mark Jenks, vice president of 787-9 development, Boeing Commercial Airplanes.
Boeing has completed the trade studies required to finalize the airplane’s overall capability and basic design, allowing the airplane manufacturer and its suppliers to begin detailed design of parts, assemblies and other systems for the 787-9. As detailed designs are completed and released, production can begin. The first 787-9 delivery is scheduled for late 2013.

“We have a disciplined process in place to ensure we have completed all of the requirements for the development stage of the program,” said Scott Fancher, vice president and general manager of the 787 program, Boeing Commercial Airplanes. “The team has done a fantastic job to get us through this important milestone.”

The 787-9 is the second member of the 787 family. A slightly bigger version of the 787-8, the airplane will seat 250-290 passengers, 16 percent more than the 787-8. The 787-9 will have a range of 8,000 to 8,500 nautical miles (14,800 to 15,750 km).

“We have been working closely with our customers for years to reach this milestone,” said Mark Jenks, vice president of 787-9 development. “We are excited about the performance and capability this airplane will offer our customers.”

The 787 Dreamliner is an all-new twinjet designed to meet the needs of airlines around the world in providing nonstop service between midsize cities with new levels of efficiency. The airplane will bring improved levels of comfort to passengers with larger windows, bigger baggage bins and advances in the cabin environment, including lower cabin altitude, higher humidity and cleaner air. Delivery of the first 787 is planned for the fourth quarter of 2010.
