Assembly issues continue to slow delivery of the Boeing 787 Dreamliner, which is now almost three years behind schedule. Workers at Italian subcontractor Alenia apparently incorrectly installed fasteners where the horizontal stabilizer attaches to the fuselage on some aircraft. Boeing employees in Seattle are now correcting the problem.
“This is not a design issue or a flight-test finding,” says Scott Fancher, vice president and general manager of the 787 program. “This is a straightforward workmanship issue with the installation of a couple of shims and some associated fasteners.”
One wonders if it really was worth outsourcing all the fabrication for this project. Is the Italian subcontractor being backcharged for the repair work? How many more defects will be allowed from a subcontractor before finding a new source for that particular assembly?
