SEATTLE, Wash. (AP) — Boeing is settling more of the roughly 150 lawsuits filed by families of passengers killed in two crashes.

A Seattle law firm said Friday it settled four of the 46 cases it’s handling for families of passengers who were on board a Lion Air Max that crashed off the coast of Indonesia in 2018.

Thursday, a federal judge in Chicago approved settlements of nine other cases involving the same crash.

Terms of the settlements were kept confidential at Boeing’s insistence, according to lawyers.

Chicago-based Boeing says it has settled dozens of claims.

Boeing is working to fix flight software that played a role in the crashes.
