Deadly crash may be
linked to ice buildup on plane wing
Farmington pilot, co-worker were killed in Idaho accident
The type of airplane that crashed near
Salmon, Idaho, during a light storm Monday is the subject of a review
by U.S. and Canadian authorities for its vulnerability to accumulate
ice on its wings.
The
U.S. National Transportation Safety Board and Canada's Transportation
Safety Board are investigating eight separate accidents involving the
Cessna Caravan since 2001 that have killed 37 people. In each case,
the Caravan, also known as the Cessna 208B, lost airspeed and crashed
in weather conditions known to cause icing, according to the NTSB.
A
"safety recommendation letter," the culmination of more than a year
and a half of review, is expected to be released next week, said NTSB
spokesman Paul Swan.
The
Cessna 208B also is the subject of at least two icing-related lawsuits
filed against Cessna Aircraft Co. and operators of the aircraft. The
Chicago-based Nolan Law Group says more than 50 people have died since
1990 in Cessna 208B crashes in which icing was a factor. Pilot Fred
Villanueva, 60, of Farmington, and co-worker Raymond Ingram, 32, of
Salmon, died Monday when their Cessna 208B, owned by Idaho-based
Salmon Air, crashed about 10:30 a.m. The plane had departed Salt Lake
City at 8 a.m.
The
plane was purchased new in 2001, said Salmon Air president JoAnn
Wolters. It was the first plane the company purchased new and was its
only Caravan, she said. Salmon Air is a passenger and cargo service
that operates its 11-plane fleet in Utah and Idaho.
"We
are just a mom-and-pop operation that has grown up over 24 years. This
has been a blow to the great people that work with us," Wolters said.
NTSB
investigators were on the scene of the Idaho crash this week to piece
together the cause, which was still unknown on Thursday. A preliminary
report, expected to be released soon, will not conclusively link the
crash to ice buildup on the wings, said Debra Eckrote,
NTSB spokeswoman.
"We're
still working on gathering all the facts," she said.
Icing
conditions - cold temperatures and cloudy skies - were reported at the
time of the crash, Eckrote said.
The
National Weather Service reported clouds, light snow and temperatures
in the low 20s at the Salmon airport Monday morning.
Though
the Cessna 208B meets the minimum standards set by the Federal
Aviation Administration for flying in icing conditions, the plane is
vulnerable to ice buildup on the wings, said Nolan Law Group attorney
Tom Ellis, whose firm represents the families of victims in four
Cessna 208B crashes.
Nolan
Law Group to date has filed lawsuits in Alabama and Ohio, alleging the
maker and operators of the plane knew about its icing problems and
failed to correct them.
A
civil complaint filed earlier this year claims that the March 15,
2002, death of pilot Mark Stephen Blevins, who was killed when his
plane went down in Alma, Wis., was caused by a faulty wing design that
gave the airplane "a dangerous propensity for degraded performance in
icing and frost conditions."
A
lawsuit filed in July alleges that a Dec. 1, 2001, crash near
Bessemer, Ala., also implies that the plane's inability to handle
icing caused the deaths of Michael O'Neill and Dimitri Tohovitis.
Ellis
said he and his colleagues are "trying to effect a change to this
aircraft in the interest of public safety." He said "it's a shame" the
Cessna Aircraft Co. has not earlier addressed the problem, which he
said was first discovered in the early 1990s.
"Why
do we have to wait for the pain of the federal government to make the
change?" he asked.
A
spokesman for Cessna declined to comment on the lawsuits or Ellis'
allegations.
As ice
builds up on the wings, the friction that creates lift from the air
going over the top of the wing is reduced, which can cause the
plane to lose airspeed and, in extreme
conditions, stall, according to a supplemental pilot safety and
warning manual produced by the Cessna Corp.
"The
best course of action is to avoid icing conditions," the manual
states.
Wolters said Villanueva was properly trained to fly the 208B and was
aware of the procedures necessary for flying the Caravan in icing
conditions.
According to the FAA, there are 584 Cessna 208Bs licensed in the
United States, including six in Utah. The $1.5 million plane, which
comes in four models, is used for freight or passengers and can seat
up to 10 people.
Other
than concerns about icing, the Cessna 208B has an excellent flight
record, pilots say.
Ontario pilot Shawn Harmon, who has flown the Cessna 208B for about
five years, said the plane's redundant fuel and electrical systems,
along with a user-friendly setup and excellent navigation systems,
make it reliable and easy to fly.
"It's
a terrific single-engine airplane," Harmon said. He acknowledged,
however, that the plane has too many unprotected areas to sustain
flight in moderate to heavy icing conditions.
"It
can happen instantly, but you train for it," Harmon said. "We have
enough experience with it to accept the limitations of the airplane."
