CHICAGO -- Democratic Sen. Jay Rockefeller of West Virginia, who is in charge of regulating the national aviation system, said he would likely hold hearings about the problems that led to the grounding of Boeing Co.'s Dreamliner, The Hill reports.

Rockefeller said that the Senate Commerce, Science and Transportation Committee "would likely look into the 787's problems, even if the airplane is eventually cleared to return to flight by the FAA," the Hill writes.

Chicago-based Boeing has told airlines it is confident of fixing battery problems on the 787 Dreamliner soon, Reuters reported today.
