    The first 6 787's will be slightly overweight.

    HOWEVER:

    Bear in mind that inspite of that, it is still well within the defined weight parameters Boeing gave for customers (ie, underweight).

    The reason its "overweight" is due to Boeing having a more ambitious internal target. The airlines will get the product underweight.

      Any reason why the first 6 will be overweight, and not the subsequent ones?

        AFAIK, these will be used in the test programme- and subsequent 787's will have their weight already trimmed by the time they enter final assembly.

              Boeing's internal weight target is 2% below what it guarantees to the airlines. Initially, the 787 ran overweight, so Boeing started a weight-reduction effort called Blockpoint. Airplanes 7 and on will benefit from this program, which involved a thorough analysis of the airplane's structure, with weight taken out wherever possible. I don't know if Boeing will pay a weight penalty on the first six airplanes, which will be refurbished after flight testing and delivered to customers.

              Bear in mind that Boeing sells the 787 based on its total cost of ownership. This includes things like fuel burn and maintenance costs. The actual maintenance costs are projected to be below the guarantees, and it's looking like the engines will have better fuel burn than anticipated.

                No they wont.

                The target weight is still below that which is agreed by the customers.

                The internal Boeing target is far more stringent. Airlines will get there 787s underweight as promised.

                      Tight squeeze indeed. Works well for the 787-3/8/9 wings but one can wonder whether any potential 787-10 or even -11 wings would fit just as well.
