Jetliners' wingtips touched the ground during two landings, one in Charlotte, N.C., on Dec. 13, the other in Austin, Texas, on Dec. 24. And in Jamaica, a plane on Dec. 22.
FAA officials said in a statement Friday they will conduct a review of the mishaps to see if there might be a larger issue.
The statement says that if needed, the FAA will work with American on corrective action.
A spokesman for American, a unit of Fort Worth, Texas-based AMR Corp., told the Fort Worth Star-Telegram on Friday that the company is cooperating with the FAA and conducting its own investigation.
