Boeing engineers have completed detailed design and computer validation of the final aspects of the 787 wing fix, the company says.Boeing says the the final parts are currently being fabricated for the side of body modification that has kept the 787 grounded.
Once complete, the parts will be shipped to Everett installation aboard the static test airframe (ZY997) followed by full-scale validation. Installation is also currently progressing on ZA001 as well.
Boeing declined to say how long the final fittings would take to fabricate, but that they would be ready "soon".
Boeing CEO Jim McNerney said in last Wednesday's third quarter earnings call that the design and validation would be complete by week's end.
The company will continue subcomponent testing of the wing fix through the full-scale validation process, but adds that the data collected on the reinformcement so far has provided positive results.
Program sources tell FlightBlogger that Boeing engineers were troubleshooting detailed design issues with the four highest-load stringers at the aft of the wing as recently as ten days ago, but Boeing's detailed design completion appears to signal the design obstacles have been overcome.
The company has maintained that the first 787, ZA001, currently being modified inside Paint Hangar 45-04 is on track for first flight by the close of 2009.

Thank you for the update! I will be so happy to see the Dreamliner fly. I think it is a great idea that Boeing is not using firm dates anymore.
It would be interesting to be in the same room with these Engineers and listen to them talking about ideas to get it in the air asap.

Mark, I share your feeling about Jon's reporting. It is the best.
I'm glad to hear that it seems that the engineers are over the "hump" in the design. I'm looking forward to more positive news about the 787 program. It is at the bleeding edge of implementing new aviation tech. but it doesn't have to be the project that dies for it.
I'm ready to see her fly.

Thanks for the insight, great report! That has to be the best wing shot/photo I've seen of the 787. Magnificent style, looks like a gull wing. Love the lighting and background to showcase what this wing is about.
