Airworthiness Directives; The Boeing Company Airplanes

FAA / Federal Register · 2019-23788

The FAA proposes to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 787-8 airplanes. This proposed AD was prompted by a report of failure of a wing strut leak test due to a missing bolt on the firewall. This proposed AD would require a one-time leak test of the strut upper spar areas for the left and right wing struts, and corrective action if necessary. The FAA is proposing this AD to address the unsafe condition on these products.
