DALLAS (AP) — American Airlines says it will do repairs on 49 more planes to prevent the seats from coming loose during flight.
That's the same problem that caused the airline to ground 48 planes last week.
Airline spokeswoman Andrea Huguely said Friday that crews will add a backup locking device to seats in most of its Boeing 767s. Those are wide-body planes used on international flights.
Seats came loose on three flights involving two different Boeing 757s earlier this month. Huguely says there have been no similar incidents with the Boeing 767s, but the airline is fixing the seats as a precaution.
Huguely says the work started Thursday and will be done by Oct. 21. She says the work will be done overnight and the airline won't have to cancel any flights.
