Japan airlines 787 took an engineering flight to check on work performed recently. Another Japan Airlines 787 took a short functional check. A UPS 767 took its second flight. A Cathay Pacific 777 took a taxi test. Flight test was rescheduled due to bad weather.
I believe they have been woring on a number of 787's and you will see deliveries of those reworked planes in the next two weeks. April should see a significant number of rework completions. While the rework takes only 10 to 14 days on the delamination, there is also rework to update to latest specs on the early production models. That rework is picking up based on what I have seen on the Paine field blog.
