The Forest Service and Interior contract for aircraft to perform various firefighting functions, including airtankers that drop retardant. The Forest Service contracts for large airtankers and certain other aircraft, while Interior contracts for smaller airtankers and water scoopers. However, a decrease in the number of large airtankers, from 44 in 2002 to 8 in early 2013--due to aging planes and several fatal crashes--has led to concerns about the agencies' ability to provide aerial firefighting support. GAO was asked to review agency efforts to ensure the adequacy of the firefighting aircraft fleet. This report examines (1) Forest Service and Interior efforts to identify the number and type of firefighting aircraft they need and (2) the Forest Service's approach to modernizing the large airtanker fleet and the challenges it faces in doing so. GAO reviewed agency studies and strategies, assessing the extent to which they included key elements important for understanding fire aviation needs; reviewed large airtanker planning and acquisition documents; and interviewed agency officials and representatives of the fire aviation community selected to represent state agencies, aircraft vendors, and others. |
