Beschrijving:
A CSA Ceskoslovenské Aerolinie Ilyushin 18 passenger plane was destroyed when it crashed into a lake near Bratislava-Ivanka Airport (BTS).
Flight OK001 departed Prague (PRG) at 08:52 on a domestic service to Bratislava (BTS).
The ILS approach to runway 22 at Bratislava was unstabilized with a rate of descent of 22 m/s instead of 10 m/s. The speed varied from 435 to 225 km/h instead of 269 km/h, and the flaps were selected down from 0 degrees directly to full flaps. Below an altitude of 1000 m the crew used no. 2 and no. 3 engine reverse thrust. The no. 3 engine failed during this operation and the no. 4 prop was feathered by mistake. At 50 m above the threshold the crew decided to overshoot. The no. 4 engine was restarted at 40 m, but the right bank increased. The crew lost control and the Il-18 struck the water of the Zlaté piesky lake in a 60 degree right bank and a 60 degree nose down attitude. Four passengers were pulled out the wreckage alive, but one of them later died in hospital.

Probable Cause:

CAUSES:
- Use of thrust reversal at altitude under 1 000 m (3280 feet)
- Improper manipulation of the thrust levers of the inner engines
- Reducing speed under the allowed limit on final approach
- Erroneous feathering of the engine number 4 propeller
- Failure to bank the plane towards the working engines side
- The immediate cause was the attempt to start engine number 4 at low speed and altitude
