Section 401 of the bill prohibited a state or local government from preventing people associated with disaster counseling services who are not licensed in that state from providing those services for up to 60 days after an aviation accident. Section 402 of the bill would expand a current preemption of state liability laws by limiting the liability of air carriers that provide information concerning flight reservations to the families of passengers involved in airline accidents. Air carriers are already provided immunity from state liability laws for providing passenger lists under these circumstances. Because neither mandate would require state or local governments to expend funds or to change their laws, CBO estimates that any costs associated with these mandates would be insignificant.
