Boeing 787s must be checked for wrong titanium parts

US aviation regulators are proposing new inspections for certain Boeing 787-9 and 787-10 airplanes. These planes might have a critical part, the ram air turbine forward fitting, made from the wrong type of titanium.

Aviation parts must use specific materials to handle extreme stress. If the wrong titanium alloy is used, the part could fail under pressure, creating a safety risk. This proposed rule means airlines operating these specific Boeing models will have to perform mandatory checks to ensure the correct material was used.
