American Airlines on Thursday said it is taking preventative measures to ensure seats on its Boeing 757 aircraft remain attached to the floor.
"American has instructed mechanics to pay particular attention to the seat lock plunger mechanism that secures the seat to the aircraft floor," airline spokesperson Andrea Huguely said in a statement. "Mechanics have begun taking steps necessary to ensure that no seat can become dislodged from its track."
Select flights could be delayed or canceled while mechanics complete the work, which is expected to be finished by Saturday, Huguely said.
American has been working with the Federal Aviation Administration after passenger seats on three separate flights became dislodged in recent days.
In a statement, the FAA said it was aware of American's additional inspections, and said, "our safety investigation continues and we'll take additional action as appropriate."
American officials said the loose seats were not an act of sabotage by angry workers.
