Final Report Boeing 747-412F TC-MCL 61
Judging by the aircraft fragments in this area, the impact was done by the main landing gear struts and wheels and by the engines. As a result of the impact, the RH wing flight control surfaces started to disintegrate.
At the distance of approximately 160 – 170 m from the first touchdown place, the second terrain touchdown occurred. The aircraft impacted the buildings with its RH wing and engines No.3 and No.4. The RH wing tip with the winglet as well as small RH wing fragments were found in this area (Figure 29).

As the aircraft continued to move further, the RH wing disintegrated, and engines No.3 and No.4 were torn apart from it.
Then the aircraft started to turn to the right in respect to the direction of its movement, and at the same time, judging from the damage caused to the trees at a considerable height, by turning, the aircraft developed a significant bank to the right. The LH wing fuel tanks partially disintegrated. The RH main landing gear was also found in this area.
The aircraft movement along the ground surface still was of a straightforward character. The aircraft was moving forward with its LH side at the front, touching the ground with its lower fuselage. As a result, almost all the buildings, located in this area, were completely destroyed (Figure 30).---- INTERSTATE AVIATION COMMITTEE
