Southwest faces Tuesday deadline from FAA

DALLAS (AP) - Southwest Airlines Co. faces a deadline Tuesday for settling a dispute with regulators over the use of unapproved parts on more than 80 planes.

Southwest says it has replaced the unapproved parts in more than 25 planes but needs more time to find parts for the remaining jets. Without an extension, the Federal Aviation Administration could force the airline to ground some planes.

The airline said Monday it wants more time to continue replacing parts without disrupting service for customers.

FAA officials said the unapproved parts - designed to push hot engine exhaust away from the wings - didn't pose an immediate safety hazard. On Aug. 22, they gave Southwest 10 days to fix the problem.
