Firefighting planes hampered by lack of spare parts

CHEYENNE, Wyo. (AP) — The demise of the only company that manufactured a device specially designed to spray fire retardant from the back of U.S. military C-130 cargo planes has some experts worried about the future viability of a program that has helped fight wildfires for 40 years.

The Modular Airborne Firefighting System is a bus-sized device that can be shoved into the belly of a cargo plane and then used to spray retardant, or slurry, at 3,000 gallons in less than 5 seconds. The $4.9 million device's only manufacturer, Sacramento, Calif.-based Aero Union, went out of business in August, and no other company has replaced it. Critical spare parts also are no longer being made.
