  • 787 flies again - for 17 minutes
    Posted by Guy Norris 7:55 PM on Dec 03, 2010

    Boeing’s first 787, ZA001, briefly flew again today. The aircraft completed a short 17 minute hop from Boeing Field to Paine Field, Everett where it joins ZA004 in maintenance lay-up. No word yet from Boeing on when the revised 787 certification schedule is expected to be announced, though ground test work meanwhile continues on other 787s – some of it apparently directly connected to the fall-out from the Nov 9 in-flight fire incident which led to the latest program delay.

    ZA003, which remains at Boeing Field alongside ZA002 and the two General Electric GEnx-1B powered test aircraft ZA005 and 006, is today conducting data monitoring checks of the integrated cooling system (ICS). Along with the power electronics cooling system (PECS), the two provide critical cooling to the 787 electronic systems.

    Both use Eaton-provided quick-disconnect coupling and hoses, as well as metal tubes and ducting supplied by Pfalz-Flugzeugwerke of Germany. The ICS and PECS provide liquid cooled thermal management across an array of electrical systems and instruments within the 787, including it is thought, the P100 power distribution system at the heart of last month’s electrical fire.
