Southwest Grounds 38 Jets

Southwest Airlines grounded 38 jets Wednesday after finding what it called an "ambiguity" in their inspection maintenance records.

The Dallas-based carrier, which runs about 80 percent of the traffic out of Houston's Hobby Airport, also indicated more interruptions could be coming if the need arises during its own investigation into plane inspections.

The airline this week suspended three workers after getting hit with a record $10.2 million proposed fine by the Federal Aviation Administration because of inadequate inspections for fuselage cracks. It also hired an outside investigator.
