China's aviation watchdog Thursday moved to allay fears about safety on Boeing 737 aircraft, saying an emergency inspection directive issued this week was simply "routine," after an isolated incident involving the reputable jetliner in Europe earlier this month. The Civil Aviation Administration of China (CAAC) ordered domestic airlines to inspect a mechanism that controls tail flaps on 160 Boeing 737 aircraft, days after the US Federal Aviation Administration (FAA) issued an emergency airworthiness directive demanding airlines do so for safety reasons. The watchdog said in a statement on its website (caac.gov.cn) that a similar directive issued March 15 was part of the CAAC's daily safety management routine and that between 1986 to 2009 as many as 6,502 such directives were issued for civilian aircraft registered in China. The directive could World of warcraft gold, mean a compulsory inspection, a corrective measure or restriction on use of the aircraft if it is not in a reliable condition. The CAAC has ordered domestic World of warcraft gold airlines to perform a detailed inspection of Boeing 737-600, 700, 800, 900 and 900ER models to ensure normal flight operations and safety. The inspection results must be submitted to Boeing within 10 days of the directive. Ding Ling, a staff member with the CAAC, told the Global Times that so far the administration has not re-ceived reports of any faults with the Boeing 737s. On March 12, the FAA ordered maple story mesos, airlines to check some 600 Boeing 737s for loose elevator tabs caused by fractured mounting lugs that help control the tail flaps. The maple story mesos directive concerns flaps on the horizontal tails of the jets, according to the Associated Press. Media reports said that on March 2, a Boeing 737-800 jetliner operated by Ryanair, an Irish low-fare airline, malfunctioned in flight. The plane experienced severe vibrations en route from the Netherlands to Madrid, Spain and was forced to make an unscheduled landing in Belgium. The ensuing investigation wow gold, found "extensive damage" to the left elevator, a movable flap on the horizontal tail that controls the pitch of the airplane, up or down, the AP reported. A leading specialist assigned wow gold to check the Boeing 737s in Beijing declined to give his name, but said the safety hazard warning from Boeing was one of numerous regular notices issued by the manufacturer and passengers need not be concerned. "Domestic airlines have already started their inspection, and the issue is not as serious as some expected," he said. The CAAC's statement contradicted a National Business Daily (NBD) report, which said, citing an unnamed CAAC official, that the problem was a "potential safety hazard." The report said any domestic world of warcraft gold airline that does not fully carry out the inspection will be prohibited from taking off. The Boeing 737 series is one of the most world of warcraft gold popular in China. The NBD report said over 600 Boeing 737s were currently in use on the Chinese mainland. Boeing supports the CACC's rule and is committed to the safe operation of its airplanes, and is working with the FAA and its airline customers to assure compliance with this rule, Boeing said in a statement to the Global Times. Wang Yukui, spokesperson of Boeing China, told the Global Times that the directive was triggered by the incident involving the Boeing 737-800 in Europe earlier this month. "This is only an individual case. In order to prevent similar accidents from happening elsewhere, Boeing issued the maintenance notice to all its clients on March 10," he said. "This shows the importance with which the CAAC regards the incident and its commitment to guarantee the safe operation of its airlines," Wang said, adding "no airplanes will be allowed to take off if only a tiny safety hazard is found." China's three major world of warcraft power leveling, airlines - Air China, China Eastern and China Southern – all have Boeing 737s in service. An official with Air China, who declined to be named, told the Global Times that the company has received notices from both Boeing and the CAAC and an inspection is under way. "So far, no problems have been world of warcraft power leveling discovered on any of our Boeing 737 airplanes," the official said. Tan Wangeng, general manager of China Southern Airlines, told the Legal Mirror that it has already conducted inspections on its two Boeing 737 planes. "No defects have been found from the inspection," he said. Song Bufu, a 31-year-old regular air traveler, told the Global Times that he would avoid using Boeing 737s for the time being. "I'd rather book to fly on an Airbus or another Boeing model. I think it's quite normal for passengers to have this kind of reaction to such news," he said. Globally, the Boeing 737 family is the best-selling commercial jet in history, and more than 7,000 orders have been placed, according to the company's official website. There have been two major crashes involving Boeing 737s in China. In 1992, a China Southern Boeing 737-300 aircraft crashed, killing all eight crew members and 133 passengers. In 1997, the same model with the same airline crashed, killing two of the nine crew, and 33 of the 65 passengers.
