Back in September 1997, the United States Federal Aviation Administration examined Indonesia's airline aviation under the International Aviation Safety Assessments (IASA) Program and gave it a tick in the box. Since then, airline deregulation has caused a lowering of standards. So, following a consultation with the Indonesian civil aviation authority on March 6, 2007, the
FAA has declared that Indonesia no longer meets ICAO safety standards. Its rating was lowered from Category 1 to Category 2. That pronouncement means that the subject country either lacks laws or regulations necessary to oversee air carriers in accordance with minimum international standards, or that its civil aviation regulatory authority is deficient in one or more areas, such as technical expertise, trained personnel, record keeping or inspection procedures. Part of IASA's remit is to make such classifications available to the traveling public (
