Airport officials said the pilot noticed the leak shortly after taking off from Raleigh for Chicago around 8:15 a.m. Sunday. The first attempt at an emergency landing was scrapped, but the pilot brought the plane down safely as emergency crews stood by on the second attempt.
Authorities say none of the 138 passengers on the MD-83 jet were injured.
Fort Worth, Texas-based American Airlines was bringing in another plane to take the passengers to Chicago.
