Mountain Crash After Asymmetrical Power During Visual Approach (B-2523)

Approach and Loss of Control 40 km from the airport, the crew was cleared for a visual approach and to descend to 7,000 feet while at 7,800 feet. Three minutes later, the aircraft went out of control and crashed on a mountain slope 1,600 metres high, located 27 km south of runway 36. The aircraft was totally destroyed, and all 141 occupants were killed. ## Reported Sequence of Events It was reported that the captain attempted to level off the aircraft by raising its nose. The autothrottle responded by advancing the throttles, but the number 2 power lever remained at idle. The crew apparently did not notice this. With the right engine at idle, the autothrottle further advanced the left engine power lever to obtain the correct airspeed. The asymmetrical power condition was not corrected, and the airplane rolled to the right and crashed.
