Boeing has not produced 777 cargo planes for almost two months due to a dispute with American supplier Varo. According to court documents, the shutdown cost the plane maker up to $6.5 million per day. The problem also affected the production of 767 family aircraft, including cargo and military changes. Varo was the exclusive supplier of the critical wing component kit. After the supply cutoff, Boeing was forced to suspend related assembly operations and remove two partially assembled 777s from the final production line. The parties entered into an agreement in late September, but production of the 777 freighter did not resume until October 23. Boeing is trying to manufacture these components itself to reduce its dependence on a single contractor. The 777X program is not affected as it uses a different wing design. Failure to supply a relatively small part led to the shutdown of an expensive production chain and losses of millions of dollars.
