What the agency says
The FAA proposes to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 787-9 and 787-10 airplanes. This proposed AD was prompted by reports of multiple supplier notices of escapement (NOEs) documenting pressure deck splice fittings that were possibly manufactured with an incorrect titanium alloy material. This proposed AD would require an inspection of the attach fittings and upper splice fitting of the stub beam horizontal pressure deck (HPD) to determine the type of titanium alloy material, and applicable on- condition actions. The FAA is proposing this AD to address the unsafe condition on these products.
