Complete "Agree" with MechEngr as to importance of knowing the particulars insofar as any engineering, manufacturing and production, and potentially certification, issues are concerned.
For the present, this SLF/attorney comments that the individual raising these concerns has engaged the services of a truly heavy-hitter attorney. Based only on press reports and absolutely no personal knowledge whatsoever, consider that Attorney Debra Katz, founding partner of Katz Banks Kumin in Washington, has already evidently driven extensive media and press coverage, and arranged for a spotlight appearance before Ccongress.
From the New York Times article: "Mr. Salehpour’s concerns are set to receive an airing on Capitol Hill. Senator Richard Blumenthal, Democrat of Connecticut and the chairman of the Senate Homeland Security and Governmental Affairs Committee’s investigations subcommittee, is planning to hold a hearing with Mr. Salehpour on April 17. Mr. Blumenthal said he wanted the public to hear from the engineer firsthand.
'Repeated, shocking allegations about Boeing’s manufacturing failings point to an appalling absence of safety culture and practices — where profit is prioritized over everything else,' Mr. Blumenthal said in a statement." (internal quotation as in NYT article).
And, according to the law firm's website, Attorney Katz was "[r]ecognized by the Washington Post as '
the feared attorney of the #MeToo movement,' [and she] has been successfully litigating employment discrimination, civil rights, and whistleblower protection cases for nearly 40 years." (internal quotation as in original)
In my law firm years I had exactly one matter defending claims brought by a D.C. whistleblower legal specialist; there was pretty extensive use of press releases (it was circa 2006) and it was, in a word, a wild ride. (Health care field, not aviation, client). Based on all this, and discounting some for "politics", Boeing appears highly likely to be gettin' into some chop over this, I'll bet.
