The U.S. Federal Aviation Administration (FAA) identified a number of omissions in Boeing’s documentation, submitted in late April, and has sent portions of it back to the planemaker, one of the people said.
A second person said it was too early to say whether FAA concerns would lead to a new delay in resuming deliveries, which have been suspended for the past year due to production flaws.
Boeing Chief Executive Dave Calhoun highlighted the submission in the company’s April 27 earnings call, calling it a “very important step” and saying it was preparing the first 787s for delivery, but stopped short of providing a date.
A Boeing spokesperson said the company continues to have a transparent dialogue and work closely with the FAA on the remaining steps.
An FAA spokesman declined to elaborate, saying only, “Safety drives the pace of our reviews.”
