Boeing is inspecting more than 400 stored 737 Max jets after discovering tools, rags and other debris left in the fuel tanks of newly built planes.
Bloomberg reports that the checks aren’t likely to create a new delay for the Max, which could be cleared to fly by midyear.
Chicago-based Boeing has been working with regulators to recertify the 737 Max and end a grounding that began almost a year ago, after two fatal accidents.
The potential safety hazard is another embarrassment for the company, as its new leaders work to reassure airlines, crew members and passengers.
