According to a story in the Seattle Times, Boeing has grounded “767-based KC-46 tankers for the past week after the Air Force expressed concern about loose tools and bits of debris found in various locations inside the completed airplanes.”
A company memo at Boeing is quoted saying, “We have USAF pilots here for flight training and they will not fly due to the FOD (foreign object debris) issues and the current confidence they have in our product that has been discovered throughout the aircraft…This is a big deal.”
Flights resumed on Thursday the 28th of February. “The memo notes that eight tools were found in aircraft delivered to the MDC and two more in tankers delivered to the U.S. Air Force,” the Seattle Times reported.
