The certificate is one of the requirements to be able to operate commercially.
SAA has indicated recently that it hopes to take to the skies again in the third quarter of the year.
The South African Civil Aviation Authority (SACAA) is conducting an audit at South African Airways (SAA) for the renewal of a certificate allowing the airline to fly commercially.
SAA's current Air Operator Certificate (AOC) expires on 30 June 2021, according to SACAA.
An AOC is a certificate authorising an operator to carry out specified commercial air transport operations. It is the approval granted from a national aviation authority to an aircraft operator to allow it to use aircraft for commercial purposes. An AOC details the aircraft types that may be used, for what purpose and in what geographic region, according to Skybrary.
