Information on the location and the very clash of Yak-42. Aerosvit. 1997 year.

The collision area is located in the district of Katerini at a distance of 37 nautical miles south-west of the airport "Macedonia". This is an inclined section, covered to 40% with trees that reach 10-12 m., Exceeding 3300 feet (above sea level), on a mountainside slope with a peak at 4100 feet. The coordinates of the collision site: 40 13 33 north latitude - 22 15 03 east longitude. The surrounding area is a mountainous area with numerous ridges. Heavy snowfall a few days before the incident, on the day of the incident and the next day after the incident covered this place with snow with the thickness of the passage to the 1 meter. The area was covered with heavy fog to the height of 4500 feet.

Initially, the aircraft was close to the site from the south-east at a slight right turn on the course at an altitude of 290e 3300 feet between mountain slopes, which converge to the north. After ZSPS signaling (localizer 19: 12 *: 33 ") the flight crew try to gain altitude. Initially, the aircraft hit the trees with a roll 20 and the bow of a raised about 15-20.

The disaster at Thessaloniki. Yak-42. Aerosvit. 1997 year.

Investigation showed that at the first collision the aircraft was structurally intact and was in controlled flight mode.

Initially, the right wing hit the tops of trees, which were cut at an altitude of 10 meters from the ground. Later, the fuselage collided with trees that were broken at an altitude of 6,4 and 1 meter from the ground. The last trees were torn down and torn up with a root. Finally, the aircraft hit the ground at a distance of 100 meters from the place of first contact with the treetops. After the collision, the lower part of the fuselage collapsed, while the upper part with the left wing and part of the right wing rebounded and continued moving in the same direction, crossing a small rural road along the diagonal. After 70 meters, most of the wreckage fragments were donated to the opposite side of the small road. On this site the terrain forms 60% slope upwards. Continuing the movement, the remains of the wreck turned over to 180 ° around its horizontal axis advanced by 30 meters with a slight turn to the left and stopped in a state with the leading edge of the wings in the direction of the initial trajectory of the road turn.

From the starting point touch the treetops to the major collapse of the remnants left off distance is 200 meters, at this point formed a corridor width 15 meters, which extends up to 25 meters in place the final stop major crash debris.

After the first contact with the right wing of the treetops and over the next 100 meters up to the impact with the ground plane smashed trunks of trees with a diameter of up to 25 35 centimeters. At this stage, a blow fell on the front part of the fuselage, and there was a separation of the right wing. At the same moment there was destruction of the cabin. In this place were found 3 / 4 right wing of the front lower part of the fuselage, radome, yoke, multiple units of the cab and the body of the second pilot.

Discovered piloting and navigation devices have such a strong impact damage that their inspection was not possible. However, some evidence, "the stuck" during the clashes, were supported by appropriate indications on the PSC. For example, a course 290 ° (one of the most damaged PNP11) 20 * and right turn from 12e 15e to raise the bow (both heavily damaged flight director), as well as 0,347 Mach (both airspeed indicator). Taking into account indications PSC and PFC can be assumed that the instruments in the cockpit, with the exception of the PPP leader.

Right fuselage engine, the air-conditioning unit and the left engine were left from the place where there was a rebound crash debris. All the engines are tested on the spot. The right and the left engine revealed the presence of earth and foliage drawn at a distance from the blades of inlet guide vanes of the compressor to the middle section. There was a significant bend the fan blades. None of the engines have not been found by fire damage marks.
