Still Can't Make Planes

It looks like Boeing has been using the wrong alloy of titanium for its 787 Dreamliner.

The FAA wants to mandate  inspections:

The FAA has proposed mandating Boeing-recommended inspections of about 100 787-9s and -10s for fuselage fittings that may be constructed from the wrong grade of titanium.

A draft rule published May 14 would require inspections of affected aircraft within 48 months. An alert requirements bulletin issued in February lists 97 787-9s and -10s as possibly having the noncompliant parts. All affected aircraft were manufactured from early 2016 through mid-2017.

According to the draft rule, certain pressure deck area fittings may have been installed that are made from an “incorrect” grade 1 or 2 titanium. The parts should be made from Grade 5 Ti-6Al-4V, which is stronger and has higher damage tolerance.

………

Affected parts include pressure deck floor beam brackets and fittings at certain body stations. The pressure deck is located where the wings attach to the fuselage and separates the pressurized cabin and unpressurized wheel well.

Obviously, this is an almost decade old error, but I am a bit dubious of the clams of a renewed focus on safety that have been made over the past few years.

Boeing needs to fire its entire C-Suite.
