Boeing has discovered foreign object debris (FOD) in the fuel tanks of several stored 737 MAX aircraft. Production of the MAX, which is manufactured at Boeing’s facility in Renton, Washington, was suspended last December pending the recertification of the grounded model. The exact number of aircraft found to have FOD in their fuel tanks has not been made public. Boeing has around 400 in storage.
