Taxi tests on ZA002 planned for Monday were put on hold this afternoon for an unspecified reason according to Guy Norris of Aviation Week.
When approached for explanation regarding the hold, Boeing says it doesn't comment on the testing schedule for any of its 787s.
Boeing suspended its attempt to taxi ZA002 just over an hour ago after encountering unspecified issues, despite having boarded the aircraft around midday Pacific time. The flight test team plans to have another attempt tomorrow and is now holding time open on Wednesday Aug 19 as additional margin for completing any system check out items not completed on Tuesday.
