American Airlines, the world’s largest air carrier in terms of total passengers-miles transported and passenger fleet size, announced its decision to cancel on Wednesday nearly 10 percent of its air traffic, the equivalent of approximately 200 flights.

AMR Corp, parent of American Airline, said it took this measure after the national air worthiness directive issued by Federal Aviation Administration. The air carrier will check on wiring bundles in its MD-80 planes according to AMR spokesman Tim Wagner, who issued a statement via e-mail.

"We are re-inspecting the MD-80s to make sure the wiring is installed and secured exactly according to the directive," the company said in a statement.

The Fort Worth, Texas-headquartered company has 300 MD-80s, the equivalent of about 46 percent of its main jet fleet.

"Many inspections have already been completed and the aircraft are currently in service," Wagner said. "We are in the process of completing the inspections on the remaining airplanes and will return them to service on a rolling basis throughout the day."

This isn’t the first time AMR Corp. has to cancel some of its flight because of the special maintenance audits carried out by the FAA. The agency proposed a $10.2 million fine against Southwest Airlines Co. on March 6 for flying 46 jets uninspected. Since then the nation’s airlines have gone through increased inspections.

The company said in its statement that the inspections take several hours per jet, but many of them were already checked and are now back in service. The rest of the aircrafts will return to service throughout the day, the statement said.

AMR Corp. shares were $9.50 in premarket trading on the New York Stock Exchange. Yesterday, the closing price was of $9.63 per share.
