In mid-May, Boeing 787 Vice President and General Manager Pat Shanahan expected the crucial power-on milestone to be a “photo finish” for Dreamliner One, but affirmed the milestone was “on track” for the end of June. With the end of June just three and a half weeks away, the final path to 787 power-on is in sight.
According to program sources familiar with the schedule, the “photo finish” assessment is apt with the pace of working tracking closely to, or narrowly behind, where it needs to be, though major progress for Dreamliner One has picked up in recent weeks.
Power-on, according to several 787 program sources, is targeted for the middle of this month, though Boeing has built in a buffer to utilize the entire month of June for preparations if needed.
David Hess, President of Hamilton Sundstrand told a group of reporters, including FlightBlogger, visiting its Rockford, Il facility earlier this week that, “The power-on software is done and delivered, [Boeing’s] got 100% of the hardware and software they need for power on.”
“I fully expect [Boeing] to achieve that milestone by the end of the month,” Hess declared.
According to Hamilton Sundstrand, the ” full-up red label” power-on software build was delivered May 28. On the same day, Hamilton Sundstrand also delivered the first “blue label” Safety of Flight software build for additional lab testing to Boeing.
The power-on software differs from the Safety of Flight software because the power-on software is only intended for us in ground testing and does not require equipment such as the engines to be installed. Hamilton Sundstrand anticipates further changes to the Safety of Flight software as it matures in preparation for first flight. The more finalized Safety of Flight software build is to be delivered to Boeing in the next 30 days.
Hess added that for Hamilton Sundstrand, the pacing item continues to be software development, though progress was steady.
“A month ago Boeing was pretty uncomfortable with the risk levels as they looked at our schedules as to what we had to get done. Not that we were delaying the program, but if they look out ahead of us, they had some concerns in terms of the risk levels and the amount of software work we had complete in the coming months. Now we’ve since had reviews with them, shown them schedules, and I think they’re, and I wouldn’t say comfortable, but I think we’ve shown them a plan that supports their program and we’re executing the plan.”
Shanahan told reporters in mid-May that at the time he was still waiting on items from Hamilton Sundstrand for Dreamliner One.
“I told my friend Mr. Hess, I’ll give you the best meal you’ve ever had if you get [the power supply] to me by the end of June”, Shanahan said of Hess.
Hess tells FlightBlogger that he and Shanahan had been exchanging emails in recent days regarding their deal and that, “it was time for Pat to get out his wallet.”
