JAS39 Gripen flying wrong too often. 21 people were seconds from losing one's life when a Gripen fell to the wrong altitude. Now the Accident Board recommends that the Armed Forces do anything to stop.
Since the early 2000s, an average of 45 Gripen aircraft each year come from the course or who usually ended up at altitudes where they do not have permission to be.
This is contrary to the orders they received from either the military
air battle management or the civil air traffic control, the phenomenon
known as broken clearances.
-In 60-70 percent of cases it occurs during air combat exercises and
other cases to and from the exercise area, "says Christer Westerlund,
commander of headquarters near the pilots who work in aviation safety.
When asked why pilots flying through the specified flight levels, there
are many different answers, "he says.
"There may be forgetfulness, misunderstanding and fell ushering. One
thinks of something else, especially when you are in the exercise areas.
And then when you are on the way home maybe you think too much on the
actual exercise "says Christer Westerlund.
"But that does not depend on bus flinging or attitude problems, but more
on the unconscious act, he argues.
The Accident Board is now common ground for the first time a serious
incident caused by a broken clearance and was recently completed with a
report.
The conclusion is that the Armed Forces must reduce the number of over
and flight levels with Jas39Gripen-plan to a "tolerable level".
This is implemented in cooperation with the Transportation Board,
responsible for civil aviation.
The broken-clear rings are too many and should be taken down. Although
the likelihood of an accident is very small so can the wrong flying they
cause a terrible disaster, "says Goran Rosvall, chairman of the
inquiry.
It was the morning October 3, 2007 as the pilot in the Gripen fighter
plane accidentally dropped X96I 300 feet below the level indicated by
the controller, to FL 150th
Gripen fighter plane was en route from a military drill to land in
Ronneby, where it arrived on collision course with one of Gotland
aircraft, a Saab 340 operator.
The plan, coming together with 460 meters per second and was just two
seconds away from each other, "says Goran Rosvall.
On board the Saab340 were two pilots and 18 passengers. They were en
route from Bromley to Ronneby when Gripen plane turned up its nose at an
angle in front of them.
According to the pilots Gripen aircraft was 200 feet away laterally,
while the technical equipment points to a difference of 1 000 meters in
width and 30 meters in height.
According to air traffic rules would plan to remain separate at least 5
000 m laterally and 300 feet in height.
In the Gripen the pilot came on the wrong flight level ordered the air
traffic controller that he would rise, which he did.
The same orders were pilots in Saab340 through anti-collision system
TCAS as Jas39Gripen no. However, the Gripen is visible through the
transponder on the TCAS system.
Since both the plan step in the sky was still on collision course and
TCAS gave the order "descent".
"It was uncomfortable for passengers," said Agne Widholm, chief
investigator at the crash Commission. They got to ride roller coaster...
The pilot in the Gripen fighter plane has not really been able to
explain why he ran down to a lower flight level than he had permission
to be on.
Naturally, he expresses himself so that the Accident Commission
documents that it was "extremely serious and the term clan".
