Ukraine's Ministry of Transport reported in their monthly bulletin that the cause of the runway excursion was determined to be asymmetrical thrust by the engines due to different mechanical propeller angle limits. Due to the wrong setting of the mechanical stop the left propeller continued to produce forward thrust despite being commanded into beta. The wrong mechanical stop was the result of false installation.
The investigation recommended to UTAir Ukraine to examine the structure and possible failure management of the propellers especially in beta range. The operating procedures should be reviewed to identify asymmetrical thrust.
