Jet was cleared for descent, then
crashed

At least one cause of the Cessna Citation
501 jet crash on March 15 between Carey and Hailey apparently can be ruled out.
The jet did not suffer catastrophic
in-flight structural failure and disintegrate before hitting the ground,
according to Tom Little, an investigator for the National Transportation Safety
Board’s regional office in Seattle.
However, Little said it might be months
before the NTSB investigation reaches a conclusion about the actual cause.
Little said the jet apparently struck the
ground at about a 15-degree angle then disintegrated. Wreckage was strewn along
a southwest alignment for about a quarter of a mile, he said.
At the point of impact, Little said a pool
of jet fuel, similar to kerosene in composition, had collected. This indicates
there was no explosion.
Although he declined to discuss pilot Jay
Call’s last radio transmission with controllers at the Salt Lake City Air Route
Control Center, Little said the twin-engine jet was cleared to descend to 15,000
feet from its cruise altitude and the pilot acknowledged the transmission and
began the descent.
As for a report from Mountain Home Air
Force Base controllers that the jet plunged 7,500 feet rapidly in one minute
from 16,500 feet to 9,000 feet, Little said he also would check another report
the jet rapidly lost 9,000 feet of altitude in one minute. Either descent rate
is far faster than recommended and, if true, could point to reasons for the
accident, such as sudden loss of cabin pressure that could physically affect the
pilot and passengers.
(A tragic example of lost pressurization
occurred in October 1999, when championship golfer Payne Stewart and five others
were killed when their Learjet suddenly lost cabin pressure after takeoff in
Florida and flew on autopilot at 45,000 feet for four hours before running out
of fuel and crashing in South Dakota.)
A spokesperson in the Federal Aviation
Administration regional office in Seattle, Holly Baker, said the last
transmission was at 2:10 p.m., about five minutes before the estimated time of
the crash. However, she declined to disclose contents of the last radio contact.
The crash took the life of Call, 62,
founder of the 42-state chain of 160 Flying J roadside service plazas, and
Richard "Buzz" Germer and his wife Ilene, both 56, of Sun Valley. Germer was a
friend of Call and retired executive of Call’s corporation, which is based in
Ogden, Utah. He was returning to Sun Valley after reportedly undergoing
treatment for cancer.
Wreckage pieces have been collected and
will be sent to Phoenix and studied by a joint team of investigators from NTSB,
the Federal Aviation Administration as well from Cessna and manufacturers of the
engines and other onboard flight systems.
Aircraft accident investigators search a
myriad of sources for possible causes--engine and structural failure; fuel
contamination; flight control and system malfunctions; pilot disability;
weather, and air traffic control, aircraft maintenance history, among other
factors.
Call’s last physical was 11 months ago. A
pilot of some 40 years with a commercial license and Air Transport Pilot rating,
Call was rated to fly the Citation jet, which can be operated by one pilot on
non-commercial flights.
Meanwhile, the Idaho Department of
Environmental Quality said a contractor would be hired by the jet’s insurance
carrier to remove contaminated soil and fuel at the crash site beginning next
week.
According to Bill Allred, a supervisor
with DEQ’s Twin Falls office, none of the fuel reached the nearby Little Wood
Reservoir and instead was contained in a stream by absorbent floats that have
been replaced periodically.
Although he could not estimate the amount
of fuel spilled at the crash site, the Citation was airborne only about 30
minutes before crashing.
Blaine County Sheriff Walt Femling could
not immediately estimate the cost of search and rescue personnel as well as
overnight guards at the crash site. But he said the work is generally considered
part of his department’s responsibilities.
