Secondary factor in the delays faced by the Boeing 787 program was the lack of detailed specifications provided to partners and suppliers.

FactSnippet No. 1,287,447

In previous programs Boeing had supplied high level design data, but for the 787, decided to provide broad level specifications only, on the assumption that relevant partners had the competencies to perform the design and integration work with the limited data.

The Boeing 787 meets the FAA's requirement that passengers have at least as good a chance of surviving a crash landing as they would with current metal airliners.

Boeing 787 expected to have the weight issues addressed by the 21st production model.

That same month, a Boeing 787 experienced its first in-flight lightning strike; inspections found no damage.

FactSnippet No. 1,287,451

In December 2019, it was reported that Boeing 787 had removed the copper foil that formed part of the protection against lightning strikes to the wings of the aircraft; it then worked with the FAA to override concerns raised.

Certification cleared the way for deliveries and in 2011, Boeing prepared to increase 787 production rates from two to ten aircraft per month at assembly lines in Everett and Charleston over two years.

Boeing 787 assumed a faster improvement than on previous programs which had not happened.

FactSnippet No. 1,287,456

Boeing 787 had planned to refurbish and sell them but instead wrote them off as research and development expense.

FactSnippet No. 1,287,457

Early in 2020 Boeing engineers complained about depressions in the 787's vertical tail fin, affecting hundreds of planes or the vast majority of the fleet.

In late August 2020, Boeing grounded eight 787s due to such improper fuselage shimming and inner skin surfacing issues—issues which proved to have been discovered in August 2019 at Boeing South Carolina.

FactSnippet No. 1,287,459

The FAA then began to inquire into the company's Quality Management System, which Boeing 787 had previously argued justified a reduction of 900 quality inspectors, but which had failed to detect either the shim or skin surface issues.

At this point Boeing expected a one-time inspection during regularly scheduled maintenance to address the issues and expected merely to slow 787 deliveries "in the near term".

FactSnippet No. 1,287,461

Questions were asked about the inspection process used to check the work, and Boeing worked with the FAA to fix the problem, which was said to pose "no immediate threat to flight safety" and did not require 787s already in service to be grounded.

FactSnippet No. 1,287,462

The new problems and the extension of the 13 month long disruption to 787 deliveries led to anger from buyers; a slide in the company's stock price; and demands by a subcommittee of the U S House of Representatives for a review of the FAA's oversight of the plane.

Vistara, which had been expecting delivery of four Dreamliners in 2022, indicated a lack of confidence in Boeing 787 meeting its delivery aims by arranging to lease aircraft instead.

FactSnippet No. 1,287,465

The FAA rejected portions of the package as incomplete and returned it to Boeing 787, indicating a further delay before the resumption of deliveries.

FactSnippet No. 1,287,466

In January 2008, FAA concerns were reported regarding possible passenger access to the 787's computer networks; Boeing has stated that various protective hardware and software solutions are employed, including air gaps to physically separate the networks, and firewalls for software separation.

FactSnippet No. 1,287,477

Industry experts disagreed on consequences of the grounding: Airbus was confident that Boeing 787 would resolve the issue and that no airlines will switch plane type, while other experts saw the problem as "costly" and "could take upwards of a year".
