U.S. aviation authority downgrades Malaysia's air safety rating - sources

The U.S. Federal Aviation Administration has downgraded Malaysia's air safety rating, restricting the country's airlines from adding flights to the United States, four sources familiar with the matter told Reuters on Monday. Malaysia has been downgraded to Category 2, said the sources, who did not want to be identified as they were not authorized to speak to the media.

The Civil Aviation Authority of Malaysia was not immediately available for comment. The new rating means the air carriers from the country cannot start new services and are restricted to current levels of any existing service to the United States. The carriers would also be subject to additional inspections at U.S. airports.
