You've got more faith in those yahoos than I do. So far as I'm concerned,
they couldn't find their hineys with both hands in a phone booth with a GPS.

Don't worry, I fully expect Boeing to be able to defend their design
with test data. If they couldn't, they wouldn't be able to get it
certified.- Hide quoted text -

Jim,

The 737 rudder problem was a condition that was missed by the vendor
that designed it, by the cognizant engineers at Boeing, and by the
FAA. There was nothing obvious about this problem and lots of testing
at Boeing failed to reveal it during the original certification
program. The actual occurence of the 737 rudder problem in the field
was very rare, and required a specific set of conditions for it to
occur. Once the cause of the crashes was traced to the rudder control
valve assembly, Boeing took immediate steps to retrofit the entire
fleet, and provided a specific set of instructions for flight crews to
take in the event of a problem until the units could be replaced. Are
you saying that Boeing knowingly put a defective system in the field?
I don't believe that to be true... Sometimes things go wrong despite
the best efforts of the design engineers to get it right.

Which yahoo's are you referring to? If its the FAA, I can kind of see
your point, but if you mean Boeing, I have to say that knowing a lot
of the people working in the 787 personally, and from my past
association with the company, I don't believe that Boeing is going to
push a design into the field that is as unsafe as this guy is
claiming. Boeing typically designs with wider margins than Airbus
from what I have seen.

As for throwing rocks at the FAA, that is an easy target...
