American expects to cancel more flights

American Airlines expected to cancel more flights Wednesday and perhaps beyond as it tried for a second time to comply with federal rules about wiring on about 300 of its planes.
Airline officials said they canceled about 500 flights Tuesday but didn't know how many would be scrubbed Wednesday. It depended on how quickly the airline could inspect and, if necessary, rework the wiring in its MD-80 aircraft.
American operates about 2,300 daily flights, and more than one-third use MD-80s, most commonly on midrange flights from hub airports in Dallas and Chicago.
It was American's second bout with mass cancellations in less than two weeks for failing to meet the same wiring rules set by the Federal Aviation Administration, which is cracking down on airlines after admitting its inspectors were too lax last year with Southwest Airlines Co.
Since the FAA began looking more closely at airlines' compliance with safety directives, there have been cancellations at Southwest, Delta Air Lines Inc. and UAL Corp.'s United Airlines. The agency levied a $10.2 million civil penalty against Southwest for using planes that had missed inspections for cracks in the fuselage.
Tim Wagner, a spokesman for American, said an FAA inspector checked several MD-80s Monday and found that some of the wiring work performed two weeks ago didn't meet FAA standards. At issue: the spacing and direction of cords used to secure bundles of wires in the planes' auxiliary hydraulic systems.
