THE International Civil Aviation Organisation began a three-day audit of Cambodian civil aviation Monday that officials hope will return a satisfactory verdict after the previous one last year led to the grounding of Siem Reap Airways last November. State Secretariat of Civil Aviation (SSCA) Secretary of State Mao Havannal said Monday that the results of the audit would not be known until Thursday. SSCA Director of Policy Planning, Legislation and Cooperation Sinn Chanserey Vutha said last week that he expected a “not excellent but satisfactory” pass mark from the United Nations-linked aviation body.
