DALLAS (AP) - Boeing 737s operated by American Airlines will be checked for exterior scratches above cabin doors blamed on a bolt.
American spokesman Tim Wagner says a couple of planes had scratches. Two-thirds of the 80 or so jets were checked by Friday.
He told The Associated Press that one jet was taken out of service.
Wagner on Thursday told KDAF-TV that a recently discovered exposed bolt on a jet bridge canopy was responsible. He declined to identify the airport.
Inspections should be completed in a few days. The main routes of the planes include Dallas-Fort Worth, Chicago and Miami.
Wagner says the manufacturer has scratch guidelines and "if it's deeper than the tolerance recommends, then you would take that aircraft out of service until it's repaired."
Wagner says passengers were not in danger.
