Narrative:
During the descent into Izhevsk Airport (IJK), Russia, the Antonov 24 suffered an elevator control failure. The crew attempted to use the elevator trim during their approach.
The first approach was flown at a speed of 270 km/h and flaps at 15° but the crew decided to abandon the approach because the nose pitched up. The second approach was flown at 250 km/h. flaps 15° and the elevator trim tab at +15°. The airplane fell to the right at a height of 3-5 m on finals and collided with the ground near the runway.
The investigation revealed that a nut of the elevator controls had not been attached correctly during maintenance. In service the nut loosened until the controls failed several days later.
