DALLAS — American Airlines says it will modify seats on 49 more planes to prevent rows of seats from coming loose during flight.
It's addressing the same problem that caused the airline to ground 48 planes last week — the seat rows aren't locking properly into tracks on the floor.
Crews will add a “secondary locking device” to seats in most of American's Boeing 767s, spokeswoman Andrea Huguely said Friday. Those are wide-body planes used on international flights.
Seats came loose on three U.S. flights involving two different Boeing 757s earlier this month. There have been no similar mid-flight incidents with the Boeing 767s, but the airline is reinforcing the locking systems as a precaution, Huguely said.
Work started late Thursday and will be done by Oct. 21, she said. The work will be done overnight, and the airline won't have to cancel any flights this time. It canceled at least 94 flights because of seat problems with the 757s.
