The European Commission (EC) has removed its ban on four Indonesian airlines flying over its airspace after air transport authorities addressed various safety concerns.

“Significant improvements in safety by the Indonesian civil aviation authority have been recognised ,” the EU's executive arm said in a statement released on July 14.

The four air carriers include state-run Garuda Indonesia, Airfast Indonesia, Mandala Airlines and Prime Air, are taken off the list, because their authority can now ensure that they will respect international safety standards, said the press release.

The European Union banned all Indonesian-registered aircraft from flying over its airspace in June 2007 following a report from the International Civil Aviation Organisation which criticised the country's safety standards and raised alarms over a number of air crashes involving Indonesian airlines.

The EU's blacklist, which is regularly updated, contains the names of nearly 200 airlines or companies of concern, which are either banned from operating in Europe or only allowed under strict restrictions.

Most of the airlines targeted operate out of Africa, mainly in Angola, Benin, the Democratic Republic of Congo, Equatorial Guinea, Liberia, Sierra Leone and Swaziland./.
