Ukraine's Ministry of Transport reported in their monthly bulletin that the airspeed indication was at 45 knots and did not change. Maintenance discovered the left hand air data unit did not work due to a blocked pitot tube. Sand, dust and a yellow substance of unknown origin were found inside the dynamic pitot tube. The tube was replaced. The aircraft had been parked for a prolonged period of time for maintenance, however, no protective cover had been applied to the pitot tube.
