Hurricane-hammered airports in Louisiana, Mississippi, Alabama and Texas are getting some federal help in paying for needed repairs. President Bush signed a bill on Oct. 7 that widens the range of construction at those airfields that are eligible for Federal Aviation Administration Airport Improvement Program grants through fiscal 2006. It also lets them use AIP aid for emergency operating costs. Moreover, through 2006 it waives AIPs nonfederal matching share, which is 25% for large airports and 5% for small ones.
