Work remains to be done on the tail of a 787 Dreamliner at Paine Field in Everett. With mechanics working against a backlog of 20 partly completed Dreamliners, Boeing has temporarily halted final assembly of more.

Work remains to be done on the tail of a 787 Dreamliner at Paine Field in Everett. With mechanics working against a backlog of 20 partly completed Dreamliners, Boeing has temporarily halted final assembly of more.
Unfinished Dreamliners are seen last week parked on the flight line at Paine Field in Everett. Beyond the 787's production problems, engine and electrical issues have raised reliability questions that could complicate the plane's certification for intercontinental flights.

How Boeing's commercial aircraft have evolved
What's wrong with the 787 Dreamliner?
A Rolls-Royce engine blew up on a test stand last summer. A proposed software and hardware fix has yet to be vetted by regulators.
An electrical fire on a test flight last month caused a cascading series of system failures. A redesign of the power-distribution system will have to be approved by regulators.
After those failures, the FAA has told Boeing that it won't get early certification needed to fly the 787 on transocean and transpolar routes without proof of engine and system reliability.
Alenia of Italy built the horizontal tails badly, and each one is different. Mechanics are slowly working through the 20 Dreamliners already built.
The morass of rework and unfinished installation of systems on the planes already rolled out — more than 100,000 tasks outstanding — will take many months to complete.
The supply chain is halted for the fourth time this year. The test planes are grounded. Boeing will announce, likely before Christmas, another delay in the first delivery.
As Boeing prepares to announce yet another delay for the 787 Dreamliner — at least three months, possibly six or more — the crucial jet program is in even worse shape than it appears.
The problems go well beyond the latest setback, an in-flight electrical fire last month that has grounded the test planes.
A year after the airplane's first flight, the cascade of systems failures caused by that fire, as well as two major problems since summer with the 787's Rolls-Royce engine, have raised red flags with aviation regulators.
A top Federal Aviation Administration (FAA) official 10 days ago warned Boeing that without further proof of the plane's reliability, it won't be certified to fly the long intercontinental routes that airlines expect it to serve.
