- Mechanical failure within left engine resulted in failure, led to engine being shut down.
- Aircraft made final approach on single engine but this was never stabilised.
- A little before the threshold and increase of thrust on the right engine was requested.
- The aircraft banked heavily to the left and struck the ground.
Probable cause: loss of roll control apparently owing to lack of monitoring of the flight symmetry at the moment that additional thrust was requested on the right engine, following non-stabilised approach.
