Fairchild AFB (WA) is the first Air Force installation to use
"bird balls" as part of a new program to prevent airfield bird
strikes.
The new tool, part of
the 92nd Air Refueling Wing bird-aircraft strike hazard program,
uses small, environmentally safe, black balls to cover the surface
of the water on the drainage ditches near the flightline.
The idea behind the balls is that they will block the
ultraviolet rays and prevent growth of algae and weeds, making it a
less-desirable place for the birds to roost, said Master Sgt. Stacy
Maier, of the wing’s flight safety office.
The balls also prevent the birds from being able to sit on the
water and pose a threat of flushing when aircraft fly overhead, he
said.
"Bird-strike damage can range from something as simple as a
small scratch or dent, to something as big as causing an airplane
to crash, due to a complete system failure," Maier said.
Additional positive aspects include easy installation, lack of
maintenance and ability of the balls to adjust to fluctuating water
levels, he said.
"They are also relatively inexpensive to purchase," he said.
"The 50-yard section that was filled as a trial area used a total
of 10,500 balls at a small cost of $2,000." [Just over $13 per
linear foot --ed.]
Although Fairchild is the first base to experiment with this
technology, it has been used before.
"San Francisco International Airport has used them with great
success," said Lt. Col. Lesley Spraker, the wing's chief of safety.
"Since they placed the bird balls in their open water, they have
dramatically reduced bird activity in and around the previously
open water areas."
No other Air Force
bases use this technology, he said. When the idea was presented at
the bird aircraft strike hazard conference, several military bases
and civilian organizations asked Fairchild to report the results so
they could evaluate the technology.
"We expect this to be a very low-cost solution to an on-going
problem," Spraker said. "Most other options were not practical, due
to the large size of the drainage ditch."
Other solutions were considered but were either not
cost-effective or would present other problems in the future, he
said.
Fairchild has many other precautions to prevent bird strikes.
Such precautions include covering nearby skimming ponds with
netting, using several remotely controlled propane cannons and
mounting one in the rear of a truck as a scare device.
Additionally, falconer Dave Knutson, from the wing safety
office, travels the airfield daily with his trained falcons to
clear the runway of birds.
Knutson also uses his personal hunting dogs to flush the birds
out of the grassy areas adjacent to the runway, Spraker said.
"With the combined effort at Fairchild, we have seen our
damaging bird-strike costs drop dramatically. The last damaging
bird strike was in December of 2002 and resulted in a cost of
$728," Spraker said.
Just where the displaced birds go, was not disclosed.
