Cambodia's Siem Reap Airways International and all carriers from Angola have been added to the European Commission's 'blacklist' of banned airlines.
But the update, released today, gives no specific information on whether the Commission has acted against any carriers from the European Union.
Phnom Penh-based Siem Reap Airways does not operate directly to Europe, but the European Commission states that the carrier "does not operate in compliance" with Cambodian safety regulations, nor does it meet ICAO standards.
"Significant concerns have also been expressed by ICAO with regard to the ability of the Cambodian civil aviation authorities to implement and enforce the international safety standards," says the Commission in a statement.
Angolan flag-carrier TAAG had already featured on the blacklist but the Commission has extended the ban to all airlines from the southern African state.
It says the blanket ban on Angola is based on "significant safety concerns" brought up by ICAO in an audit last month. The Commission adds, however, that it will continue "close consultation" with Angolan authorities with a view to completing a plan of corrective measures.
Angola is one of several countries - among them Indonesia, Kyrgyzstan and several African states - on which an all-inclusive prohibition on European services has been imposed.
Ukrainian carriers Ukraine Mediterranean Airlines and Ukraine Cargo Airways remain on the blacklist for failing to prove that they have implemented corrective actions on safety deficiencies.
"The Commission, together with member states, will visit both carriers before considering any modification of the operating ban," says the EC, which adds that it is pressing the Ukrainian authorities to strengthen safety standards.
Gabonese operator Nouvelle Air Affaires similarly stays on the blacklist, because there is "no evidence" of progress on corrective measures. All Gabonese carriers, except for Gabon Airlines and Afrijet, are blacklisted.
