A Russian aircraft leasing company confirmed Tuesday that it has filed the first US lawsuit to cancel an order for 35 Boeing 737 MAX jets. Avia Capital Services (ACS), a subsidiary of state-owned Russian conglomerate Rostec, confirmed to AFP a report of the lawsuit in the Financial Times, which said it was the first civil action brought by a customer against the US aerospace giant over the 737 MAX. The FT reported that ACS had filed the suit in Chicago claiming that Boeing had “intentionally” failed to disclose information about the airworthiness of the jet to its customers.
