a lawyer for the families, speaking in a press conference along with the secretary for the Adam Air KI-574 Passengers' Families Association (formed in the aftermath of the disaster), 30 of the victims' families intend to sue Boeing instead of Adam Air over the accident. This does not necessarily mean that all of the others will sue Adam Air, however, as they may not necessarily exercise their right to sue at all. Representatives of the families have explained that they believe the plane was brought down by a faulty rudder control valve, similar to the accidents involving United Airlines Flight 585 and USAir Flight 427, which went down in the early 1990s, although there is no evidence that proves this.

Adam Air has compensated the families of deceased passengers Rp 500 million (equivalent to about US$55,000 or €42,000) per passenger. It also compensated families of the flight crew. There have been calls from relatives of the dead for Adam Air to build a memorial to the victims in Makassar, South Sulawesi. Adam Air said that if an agreement could be reached, then they would fulfill the request. Aftermath Shortly after the crash, Adam Air changed the number of the
