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?
A new compression molding compound material combines the light weight, strength, and rigidity of carbon fibers with the flexibility and lower cost of glass materials in a composite compatible with automotive production.
Plastic bearings are real and millions of them are in use doing heavy-duty jobs we used to think only metals could do. Some of Germany-based igus's bearings are traveling around the world as functional parts in a car to demonstrate what they can do.
