BRUSSELS – The European Commission said on Thursday it had asked Germany to improve its system of environmental and safety certification for passenger aircraft.

“The European Commission today sent a reasoned opinion to Germany for not recognising a certificate issued by the European Aviation Safety Agency in accordance with EU rules,” the Commission said in a statement.

“The legislation concerned aims to establish common safety requirements for civil aviation in Europe,” it added. “It lays down the rules for granting certificates to specific aircraft types, in relation to safety and environmental protection.”
