text: The crew of a Turkish airlines flight are being investigated after they allowed Turkish football team captain Arda Turan into the cockpit so he could use the tannoy to congratulate his team-mates. He was celebrating after the team's 2-1 international friendly victory against Luxembourg and had gone to the cockpit to announce his congratulations over the PA system last week. But after the move was reported in Turkish media, Turkish aviation officials in the country's Civilian Aviation Directorate (SHGM) said it was a serious breach of the safety rules of the flight back from the capital Luxembourg City and warned that there would be consequences for the cabin crew. Turkish skipper Arda Turan is pictured inside the plane's cockpit during the flight in breach of aviation rules after his side's 2-1 victory in an international friendly against Luxembourg . They said that nobody other than the crew should be allowed in the cockpit during the flight and exception should be made for nobody, even the Turkish team captain and Atletico Madrid midfielder Turan. The SHGM criticised the flight crew's decision to ignore the standard safety regulations in several tweets it posted on its official Twitter account. The first tweet noted that 'Flight teams must abide by "Safe Cockpit" rules for the duration of the entire flight. No one but the flight crew should be admitted to the cockpit.' A second tweet pointed out how the pilots were in violation of the 'Safe Cockpit' rules and are subject to a £260 fine, at the very least. The safety breach comes amid heightened concerns over aviation security after the Germanwings airliner crash in which all 150 people on board died when the plane's co-pilot deliberately flew the Airbus jet into the ground.
