Analysis

The accident airplane overrotated and struck the runway with aircraft fuselage during a no flap landing. The first officer was flying the approach and when he asked for flap extension both pilots stated they did not extend. The captain elected to continue the approach. The final approach was flown with the captain manipulating the throttles and the first officer on the flight controls. The airlane bounced on touchdown. The captain assumed complete control of the airplane and completed the landing.
