Boeing Co. is inspecting more than 400 stored 737 Max jets after discovering debris such as tools or rags left in the fuel tanks of several newly built but undelivered aircraft.
The checks aren’t likely to create a new delay for the Max, which Boeing estimates will be cleared to fly by midyear, said a person familiar with the matter who asked not to be named as the matter is confidential. The company has been working with regulators to recertify the 737 Max and end a grounding that began almost a year ago after two fatal accidents killed 346 people.
