There are numerous articles that say China is the source. Several point to a US News & World Report 2/21/2000 article but I have been unable to get to the article.
a horrible accident It went into the ocean upside down I believe. No one survived.
My understanding of that terrible incident was that a jackscrew, or something of the sort, was worn to the point that it just barely passed inspection. Instead of taking the safe route and replacing, it was left on the aircraft. No idea about the mfg of the part.
Cynthia Odee (sp?), a Bay Area conservative talk show contributor, was on that flight and I recall hearing Lee Rogers of KSFO rail against Alaska for their negligence.
