Boeing is under fire in three separate but related cases alleging the aviation giant has a habit of defrauding companies into signing losing contracts, despite claiming the opposite in court, according to a lead plaintiff’s attorney.

In the most recent case filed Feb. 2, a North Carolina family office asserted that Boeing conned them into buying a near-bankrupt parts supplier while engineering its failure by secretly leasing the supplier’s facility in Santa Ana, California, out from under it.
