The International Civil Aviation Organization (ICAO) conducted a fresh audit of the aviation safety system run by the Civil Aviation Authority of the Philippines (CAAP) in what regulators there hope will lead to an upgrade of that nation’s Category 2 safety status to Category 1. Such an upgrade would spearhead the move to allow Philippine airlines to operate to the U.S. and Europe. The FAA downgraded the Philippines to Category 2 over safety concerns in 2009, with Europe blacklisting the carriers in 2010.
