Boeing finds debris in fuel tanks of many undelivered 737 MAX jets

Boeing Co has found debris in the fuel tanks of dozens of undelivered 737 MAX jets amid ongoing inspections as the Chicago-based planemaker struggles to restore the trust of airlines and the wider public in the grounded fleet.

Boeing found debris in the fuel tanks of about 35 aircraft, a company spokesman confirmed on Friday. A person familiar with the matter told Reuters that more than 50% of the undelivered 737 MAX jets inspected thus far have had debris found in them.

Several more planes are still awaiting inspection.

“We are taking steps to make sure we eliminate FOD (foreign object debris) from any and all aircraft. This is unacceptable and won’t be tolerated on any Boeing aircraft when it’s delivered to the customer,” Boeing said in an emailed statement.
