Flightblogger has revealed that Boeing will announce a slip in the 787 delivery schedule by about 3 months. Boeing is now targetting a a delivery timeframe of mid February to late March for delivery of the first 787 to ANA.
The delay is attributed to the horizontal stabilizer issues at Alenia as well as the uncontained failure of the Trent 1000 engine on a test stand in early August. Boeing had already warned that 787 deliveries could slip into 2011. It looks like they will move the 1st delivery to that time frame.
