After entering the runway, the tail was behind the threshold lights. Applying takeoff thrust, parts of asphalt were torn off, striking the left side of the horizontal stabilizer. Takeoff was continued with the crew unaware of the extent of damage. After landing serious damage to the tail was revealed. None of the passengers and crew suffered any injuries. The aircraft was repaired and test flown on May 16 before returning to service on May 17, 2015. On July 5, 2014, a CRJ-701ER of Lufthansa was involved in an incident at the same airport when it landed on the new runway 27 which was still under construction at the time.
