The FAA declined to comment further on the ongoing investigation The IAC announcement came after an Airbus A321 airliner registered in Ireland but operated by a Russian firm crashed in Egypt on Saturday and killed 224 people, but did not make a link between the certificate suspension and the crash in Egypt. The IAC could not be reached for further comment. The Rosaviatsya spokesman added that a meeting was planned for Friday between Russian airlines, Rosaviatsya and the IAC - which oversees the aviation industry in some ex-Soviet countries including Russia - about Boeing 737 certificates. A Boeing Co spokesman in Seattle said the company planned on Friday to "meet with Russian officials to understand their concerns." There are about 200 Boeing 737s in Russia, according to Reuters calculations based on data from Rosaviatsya, or about a fifth of a total fleet, both passenger and cargo.
