Boeing confirmed to me this afternoon that they have indeed started the final phase of certification testing for the GEnx-1B powered version of the 787. What is unknown is how many hours Boeing will need to fly this airplane in order to complete this final phase. Boeing is still planning to deliver the first 787s powered by this engine by the end of this month to JAL, though with the recent delamination issues that Flightblogger revealed on Saturday evening, this schedule may well be in doubt though Boeing says this will have no effect on production. Boeing doesn't expect the need to remove major structural assemblies to gain access to the affected area and make repairs to the shim which they have describe as straightforward.
