Jon Ostrower has posted a detailed update on 787 line numbers 1 through 6. Read it here.

Here's a summary:

LN 1 (Dreamliner 1): Set to be powered on again very soon. Will go through a "medium blow" pressurization test in early February. The engines nacelles cowlings have been reinstalled as well as the remaining control surfaces. As I reported earlier, Boeing has thrown a lot of resources at LN 1 and Boeing is leaving on some of the temporary fasteners for the duration of the testing program. This decision has saved a lot of time. Speaking of which the time frame for first flight looks to be shifting to the right a bit with some milestones now being classified as TBD. This includes first flight which was thought to be around the April 20th to April 24th time frame.

LN 2 (Dreamliner 2) : Dreamliner 2 had its engines and all flaps installed and work continues to center on finishing up fastener replacement. Jon is also reporting that power on should happen soon followed by the start of ground vibration testing in mid-March.

LN 3 (Dreamliner 3): Dreamliner 3 is on it's legs (landing gear) and has its engine pylons on.

LN 4 (Dreamliner 4): Dreamliner 4 is about to get its legs. This airplane, probably because it's in more complete shape, has a low priority in terms of resources.

LN 5 (Dreamliner 5): Dreamliner 5 is about to start final assembly. The main fuselage section is undergoing some traveled work installation prior to being sent into position 1 on the final assembly line. Section 41 arrived 100% complete and the rear fuselage arrived 95% complete. The pylons for the GEnx engines have been installed on the wings. This aircraft has arrived in a more complete state than the previous aircraft.

LN 6 (Dreamliner 6): The wings have come in and are virtually complete and have been painted as well.

ZY997 and ZY 998: The static and fatigue test airframes continue to have their fasteners replaced. for the static airframe this should be done by middle of February and thus set the stage for the resumption of static tests that are needed prior to first flight.
