Boeing orders 737 Max inspections after fuel tank FOD

Boeing has ordered the inspection of all undelivered 737 Maxes, after it found debris in the wing fuel tanks of some of the grounded narrowbodies. The airframer states that it has also recommended 737 Max customers globally with aircraft in active storage for more than a year to inspect the fuel tank for foreign object debris (FOD). The company states it first discovered FOD while conducting maintenance on undelivered 737 Maxes in storage at its Renton facility. “That finding led to a robust internal investigation and immediate corrective actions in our production system. We are also inspecting all stored 737 Max airplanes at Boeing to ensure there is no FOD,” the airframer states. Boeing did not state if the latest issue would impact the 737 Max’s return to service. <br/>
