Close Call at O'Hare Shows Need For Fix
By Joseph Ryan, Chicago Daily Herald Staff
Sept 5, 2007
Normally, a bird strike on a jetliner is a traumatic but not catastrophic
occurrence at O'Hare International Airport.
But on July 19, one of those common incidents set off a chain reaction that
brought two commercial jets to within seconds and 70 feet of colliding.
About 10:22 a.m. that day, a regional jet powered off the runway and hit
birds as it climbed into the air. A Boeing 737-300 waiting in line behind
the jet asked crews to check the runway for any resulting debris that could
choke its engines or affect its wheels.
The 737 was then told to leave the runway and head to a taxiway called S-4.
Instead, the pilot moved the plane to a nearby taxiway called Quebec --
right in the path of another Boeing 737-300 in the process of landing.
Controllers in the tower quickly issued an emergency order to the incoming
plane to abort its landing, and the jet pulled out of its descent, sheering
just 70 feet above the waiting Boeing 737-300.
The nail-biting close call will go down in the books among some of the worst
in O'Hare's history. Last year, a large jet came within 35 feet of hitting
another in a somewhat similar incident.
Close calls like these are not immediately reported to the public and often
are available only when the Federal Aviation Administration is questioned
about them.
The lone "high risk" near collision this year tarnishes a so-far better
safety record at O'Hare than last year's three high-level near collisions.
But it also underscores how difficult it is to account for and prevent all
the various human and mechanical errors that can lead to catastrophes.
The July 19 near collision ultimately was blamed on the pilot who changed
runways, who was not named in the report. The FAA refused to release the
names of the airlines involved.
National Transportation Safety Board and FAA officials have made preventing
near accidents on airport runways one of their top priorities for more than
decade. Still, the needed technology appears to be lacking to patch all the
perceived holes in the aviation industry's safety net.
For example, after several years of numerous runway close calls on O'Hare's
crisscrossing landing strips, the FAA installed a new multi-million dollar
ground radar system this month to provide better warnings of such incidents
to air traffic controllers.
Still, Joseph Bellino, head of the air traffic controllers union at O'Hare,
said that system wouldn't have helped in this latest situation.
The new system detects near collisions on runways. The 737-300 in the path
of the landing jet was actually on a taxiway in front of the runway.
Meanwhile, the FAA is overseeing tests of a new system that sends audio
warnings of pending collisions straight into the cockpit. That product is
years away, even if it wins the agency's final approval.
FAA spokeswoman Elizabeth Isham Cory said reducing near collisions on
runways will take multiple approaches and an ongoing effort.
"Runway incursions occur for a variety of reasons," she said. "This is
something we take very, very seriously."
Airport Layovers: Look For The Wildlife
Refuge
The Boston Globe
Sept 2, 2007
Oh, those dreaded layovers. You have a few hours or longer between flights
and find yourself wondering how much longer you can watch the repeating news
reports or stare at T-shirts in the souvenir shop.
It so happens that at many airports, you don't have to do either, because
close by is a world of wonder: a national wildlife refuge.
For information on all national refuges, see www.fws .gov. Here are some
refuges near big airports:
John Heinz National Wildlife Refuge at Tinicum is just a mile from
Philadelphia International Airport.
More than 280 species of birds can be found there, as can fox, deer,
muskrat, turtles, fish and frogs, along with wildflowers.
Contact: 215-365-3118; heinz.fws.gov.
Patuxent Research Refuge in Laurel, Md., is 30 minutes from
Baltimore-Washington International Airport.
A large visitor center offers exhibits and views of a lake that is often
full of waterfowl.
Contact: 301-497-5763; patuxent.fws.gov.
Minnesota Valley National Wildlife Refuge, a floodplain where bald eagles
nest, herons and egrets wade, and mallards swim, is two miles from
Minneapolis-St. Paul International Airport.
You can take a half-mile loop trail or hike up to 12 miles along a trail
through floodplain forests, native prairies and large lake marshes.
Contact: 952-854-5900; www.fws.gov/midwest/Minne sotaValley.
San Diego Bay National Wildlife Refuge is a short taxi and then trolley
ride from San Diego International Airport.
The refuge's Sweetwater Marsh is where endangered light-footed clapper rail
and California least tern raise their young.
In all, Sweetwater is a habitat for more than 200 species of birds.

Birds a Threat to Jets
The Record (Kitchener, Cambridge and Waterloo)
August 24, 2007
Passenger jets have been experiencing a spate of aircraft striking birds at
Waterloo Region's airport, a worldwide problem that has crashed planes and
caused billions of dollars in damages.
Transport Canada has recorded at least 10 incidents of the so-called "bird
strikes" while landing or taking off from Waterloo Region International
Airport since late June. Half of the incidents involved Boeing 737s operated
by WestJet, which launched flights to Calgary in May.
None of the strikes caused significant damage, but on July 3 a bird hit a
landing-gear door of a WestJet plane that landed in Breslau, according to a
Transport Canada report.
Wildlife is increasingly becoming a problem for aviation across North
America. [or it coud be that it is now being reported and tracked more
efficiently]
In Canada, annual reports of bird strikes have nearly doubled since 1999
-- to 1,414 from 724. Last year, Transport Canada recorded 16 incidents of
planes and birds colliding at the Waterloo Region airport -- the highest
number in recent years.
In most cases, planes collide with birds causing little or no damage to
the aircraft or injury to their passengers. But bird strikes have also
brought down aircraft, including a military jet that crashed in Alaska in
1995, killing 24 on board, including two Canadians.
The damage caused to aircraft by bird strikes reaches $1.2 billion a year
globally, and at least $12 million a year in Canada, said Bruce MacKinnon,
Wildlife Control Specialist at Transport Canada and chair of Canada's Bird
Strike Committee.
"Some airlines are very forthcoming in telling us how much it cost them to
deal with wildlife damage," he said.
"It's quite staggering. It makes the $1.2 billion per year internationally
very conservative."
The problem has become such a focus of the airline industry that experts
from around the world will convene in Kingston next month for a conference
on the topic.
While birds haven't brought down a major commercial airliner in North
America, there have been close calls.
Last month in Rome, a Delta airliner bound for the U.S. had to make an
emergency landing after flying through a flock of gulls on takeoff, damaging
both engines.
In March, a United Airlines Boeing 767 with 200 passengers struck at least
15 ducks while taking off from Chicago's O'Hare International Airport. The
birds damaged both engines, setting one on fire.
Closer to home, a Snowbird Tudor jet made an emergency landing at the
Waterloo Region airport in 2004 after a bird smashed a "grapefruit-sized
hole" in the canopy -- the transparent cockpit cover, according to a
Transport Canada incident report.
Also in 2004, two military pilots ejected from their British Aerospace
Hawk training jet at CFB Moose Jaw when they couldn't restart their engine
after it had struck a bird. The pilots survived with minor injuries but the
plane crashed and burned.
In 2005, a flying instructor was rushed to hospital after a goose
shattered the windshield of his Cessna Skyhawk and struck him in the face
during a training flight near Orillia.
It's only a matter of time before birds cause the crash of a major
commercial airline in North America, said Paul Eschenfelder, a Boeing 757
captain with a major U.S. carrier who has consulted for Transport Canada on
wildlife issues.
"You've got a 767 coming out of Rome that has both engines damaged and
you've got one coming out of O'Hare, one's on fire and the other had bird
remains in it," he said. "The facts speak for themselves."
Global warming and successful conservation efforts have caused bird
populations to explode across North America -- particularly larger birds
that travel in flocks and pose the greatest risk to planes. For example, the
Canada goose population tripled across the country between 1990 and 1999. A
single 6.8 kilogram (15-pound) goose can pack 37,000 kilograms worth of
force if it hits a plane going 555 km/h.
Milder winters mean more geese are staying in Canada longer, causing
year-round problems for aircraft.
Birds have become more accustomed to living in urban environments but are
still attracted to the large empty tracts of land at airports.
New technology has also created faster, quieter jet engines, which are
more difficult for birds to detect but weren't designed to withstand the
impact of large birds as Canada geese.
Most bird strikes happen around airports because most birds fly below
3,000 feet. Planes are most vulnerable to birds on takeoff because they need
to quickly gain speed, which they may not be able to do if their engine is
damaged by a bird.
Summer is traditionally the active season for birds and it's typically
smaller species, such as sparrows and starlings, that are an issue at
Waterloo Region's airport, said operations manager Kevin Campbell. "We're
not seeing any higher than normal activity for this time of year," he said.
WestJet spokesperson Gillian Bentley said the number of bird strikes
doesn't concern the airline.
"Certainly, we're not concerned overly with the bird strikes in
Kitchener," she said. "There are not any more than any other airport of that
size."
Any plane that hits a bird gets a maintenance check, Bentley said.
> The Waterloo Region airport spends about $10,000 to $20,000 a year on
wildlife programs, Campbell said.
Officials fenced off the runways after noticing deer frequently crossing
at night. Infield grass is kept long to deter larger birds afraid of the
predators that may hide there.
But the longer grass attracts smaller birds who feed on insects.
In July 2006, the airport got a verbal reprimand from Transport Canada for
allowing its grass to grow too long, attracting starlings, which are known
to travel in large flocks.
Airport staff found 29 dead starlings on the runway after pilots on a
Northwest Airlines flight landing from Detroit noticed "a flock of birds
flew out of the long grass," reads a Transport Canada report of the
incident.
Pearson International in Toronto uses falcons to chase away flocks of
birds, while some other airports have taken to shooting a few birds in front
of their friends to reinforce the message they're not welcome.
It all adds up to piecemeal work by industry and government that isn't
going far enough to address the issue, Eschenfelder said. There are no joint
working groups between industry and regulators to develop better practices,
and lax reporting requirements mean wildlife is one of the least understood
hazards in aviation, he said.
"We mitigate problems everyday. Wind shear is out there, we operate.
Thunderstorms are out there, we operate. Icing is out there, we operate. But
we have strategies to mitigate those.
We don't have a strategy here."
Transport Canada began requiring airports to report bird strikes last May,
as well as develop local wildlife risk- assessment plans.
Despite some regulatory gains, pilots still don't receive enough training
to manage and avoid bird strikes, Eschenfelder said.
"They don't have a clue. You show them some of these serious incidents and
their jaws drop open and their eyes pop out. Were talking about basic
rudimentary stuff that's not even there."
Governments are working to change that, MacKinnon said.
Officials are planning to set a up committee of aircraft designers,
maintenance personnel and pilots to look at the issue during the Kingston
conference.
Transport Canada and the U.S. Federal Aviation Administration are also
jointly creating an interactive bird-strike training CD-ROM for pilots.

Latest Bird-plane Collision Causes Worry
Among Airport Officials
The Columbus (OH) Dispatch
August 25, 2007
Airport officials are examining their wildlife hazard
management plan after a jet struck a flock of starlings on takeoff and had
to return to the airport for an emergency landing.
The jet, an American Eagle regional flight carrying 55 people, lost thrust
in one of its engines on Aug. 17 before returning safely to Port Columbus
International Airport, said Rod Borden, chief operating officer of the
Columbus Regional Airport Authority.
"We periodically get bird strikes, but I can't recall one that we would view
as being that serious," Borden said.
It took workers about 40 minutes to remove about three dozen dead starlings
that had fallen onto a runway.
Starlings, which generally weigh less than four ounces and travel in large
numbers, can seriously damage aircrafts. In 1960, an Eastern Airlines plane
crashed into the Boston Harbor after a flock of starlings damaged its
turboprop engines, killing 62 people.
"They are sort of like feathered bullets. They are a dense bird and they fly
in dense flocks," said Richard Dolbeer, who heads the U.S. Department of
Agriculture's airport wildlife hazards program.
There are typically around 100 million starlings in North America at the
beginning of the nesting season in the spring. By late summer, the starling
population rises to an estimated 250 million.
Airport officials in Columbus have noticed an increase in the pesky birds,
and might ask the USDA or an outside consultant to help develop ways to
reduce the numbers living on or near airport grounds, Borden said. He
speculated that new construction at the airport might turn over fresh dirt,
exposing insects that attract the starlings.
Statistics from the USDA's Wildlife Services Division indicate that, from
1990 to 2006, starlings were involved in 1,686 out of a total of 71,670 bird
strikes by aircraft.
Growing tall grass on airport grounds and setting off loud pyrotechnics like
propane cannons can deter birds from nesting at airports, Dolbeer said. Port
Columbus uses some of those methods and also is considering cutting some
trees.
The airport would consider culling some of the bird population only as a
last resort, Borden said.
