Incident Overview

Description
China Yunnan Airlines flight 5210, a Canadair CRJ-200, crashed following a loss of control after takeoff from Baotou Airport, China, killing all 53 occupants and 2 persons on the ground. Regional Jet B-3072 was parked overnight at the Baotou Airport in cold weather conditions. Prior to departure on the morning service to Shanghai (SHA), flight MU5210 was not de-iced. The wings were contaminated by the overnight frost, which severely degraded the aerodynamic characteristics of the wing. Shortly after the airplane rotated, it entered a stall. The pilots were not able to regain control. The CRJ200 crashed into a frozen lake in Nanhai Park just two kilometers past the runway. The aircraft struck a park ticket office, killing two park employees, before it crashed into the water.
