The US regulator FAA has retained the highest aviation safety ranking for India, a senior official said Tuesday. The Federal Aviation Administration (FAA) carried out an audit of the Directorate General of Civil Aviation (DGCA) in July this year. The official said that the FAA on Tuesday formally confirmed that India's International Aviation Safety Assessment (IASA) rating remains 'Category 1'. Category 1 means the carriers from the assessed state may initiate or continue service to the US in a normal manner and take part in reciprocal code-share arrangements with American carriers. The FAA carried out an audit to confirm India's adherence to the standards laid down by the ICAO and oversight of Indian airlines. "During consultations held with the FAA in early November, the DGCA presented the actions taken to address the findings of the July 2018 audit," the DGCA official said. According to him, the FAA has formally communicated that India is adhering to the safety standards of the ICAO (International Civil Aviation Organization).

The American regulator conducts IASA programme to assess the Civil Aviation Authority (CAA) of each country that has carriers operating to the US. An IASA assessment determines if the foreign CAA provides oversight to its carriers that operate to the US as per the international standards. Under the International Convention on Civil Aviation (Chicago Convention) each country is responsible for the safety oversight of its own air carriers. Other countries can only conduct specific surveillance activities, principally involving inspection of required documents and the physical condition of aircraft.
