The US Federal Aviation Administration (FAA) has downgraded Malaysia’s air safety to a Category 2, following a review.

The FAA Review of the Civil Aviation Authority of Malaysia (CAAM) said that Malaysia is deficient in one or more areas.

CAA in a statement said that the revise audit will prevent the country’s airlines from operating new routes to the US and will impose additional inspections on Malaysian airlines at US airports.

The FAA Review covered areas of technical expertise, trained personnel, record-keeping, and/or inspection procedures.

CAAM has requested the FAA to conduct a re-assessment within the next 12 months with the intention of having its Category 1 status restored.
