A limited evaluation of the production UH-60A Black Hawk anti-ice and deice systems was conducted to determine the capability to operate safely in a moderate icing environment. Artificial and natural icing tests were conducted at St. Paul, Minnesota, from 11 February through 31 March 1980. Testing was performed by the United States Army Aviation Engineering Flight Activity and consisted of 27.1 productive flight hours. During these tests, three deficiencies and fourteen shortcomings were noted. The two icing related deficiencies are: failure of the droop stops to return to the shutdown position after ice accumulation on the main rotor head and failure of the anti-flapping restrainers to return to the shutdown position after ice accumulation on the main rotor head.
