MOSCOW, June 27 (RT) - Former mechanic Richard Cuevas who worked on Boeing Co.’s 787 aircraft alleged he observed improper manufacturing at a subcontractor for the Dreamliner program, the new whistleblower said in a statement. He claimed he observed “substandard manufacturing and maintenance practices” on the 787’s forward pressure bulkhead — critical to maintaining cabin pressure.

Cuevas estimates the alleged problems he witnessed may impact as many as a dozen planes, according to the statement. Boeing said in a statement that the claims were reported previously and thoroughly investigated and posed no safety concerns.
