Faulty Fasteners Slow Boeing Production

Boeing faced further slowing of its strike-plagued commercial airplane production while it tracks down 346,000 faulty fasteners supplied by Cordant Technologies, according to Aviation Week & Space Technology.
About 20 new 737s, 757s and 777s are using 3/16-inch fastener collars made from a different aluminum alloy, 7050, than the 2024 that was specified, according to Boeing. �Although the parts do not present a near-term safety-of-flight risk, they are prone to cracking and corrosion and eventually must be replaced,� according to Aviation Week.
�Cordant reportedly used the wrong material after receiving an improperly identified shipment from one of its suppliers.�
The aircraft in use were quickly identified. Boeing will not deliver a new aircraft until it is FAA-compliant.
