Sukhoi Civil Aircraft Co. plans to improve the landing gear on the entire fleet of Sukhoi Superjet 100s following two incidents on Aeroflot-operated aircraft that suffered broken rods on the actuator of the landing gear bay door. The first incident took place in Minsk in December 2011. On March 16, another Aeroflot’s SSJ 100 flying from Moscow to Astrakhan was forced to return to Sheremetyevo Airport for the same reason. According to a spokesman at United Aircraft Corp. (UAC), Sukhoi’s parent, the aircraft have been repaired. The manufacturer planned to install the reinforced actuator rods on all other aircraft of this type by March 25 without taking them out of operations. The other four SSJ 100s operated by Aeroflot will be repaired at the airline’s home base in Sheremetyevo, Armavia’s lone aircraft will be repaired in Yerevan.

“The designer and manufacturer of the SSJ 100 landing gear, Messier-Bugatti-Dowty, will take part in these activities,” said a UAC representative, adding that this defect didn’t show itself during the aircraft’s testing and it doesn’t threaten the passengers’ safety.
