the Failure of the system of retracting the flaps caused the crash of Tu-154
the flight data recorder, which was recovered from the crash site of Tu-154, registered the failure of the system of retracting the flaps, during takeoff provides extra lift on the wings of the plane, writes “Kommersant” with reference to close to investigate the source.
However, according to respondents edition experts, newboro flap is at least unpleasant, but not catastrophic incident. This situation and the necessary actions of the pilots when it occurs is described in the operating manual of the aircraft and the pilots practiced on simulators. The crew of the crashed Tu-154 for some reason was not able to solve this problem and, moreover, their actions only exacerbated the situation.
As suggested by the sources, the pilots, trying to compensate for a smooth departure of the aircraft into a dive, started to pull the wheel itself, increasing the operation of engines. This could cause the exit of the plane in the so-called supercritical angles of attack, to lose speed and crash into the sea.
Despite the likely versions that are consistent with the eyewitness testimony and video of the short flight, the experts do not intend to abandon those assumptions about the causes of the disaster. According to “Kommersant”, did not completely rule out terrorism, violations of alignment at take-off or, for example, the collision of the aircraft with a flock of seagulls. To put an end to the latest version, by the way, prevents a large number of bird feathers found on the surface of the water at the very beginning of the operation. In addition, the dominance of birds over the sea complained and the pilots of rescue helicopters.
the version with the birds will be confirmed or rejected finally after experts will find and study the engines of the aircraft, which can stay Biologicals.
As earlier reported “Газета.Ru” Tu-154 crashed into the Black sea at speeds over 500 km/h.
