The Federal Aviation Administration (FAA) is proposing a $304,000 civil penalty against Great Lakes Aviation of Cheyenne, Wyo., for allegedly conducting 19 flights with aircraft that were not in compliance with Federal Aviation Regulations.
Great Lakes operated the aircraft in conditions in which the carrier could reasonably expect frost, snow or ice to adhere to the planes, the FAA alleges. The FAA maintains that Great Lakes flew Beech 1900 aircraft out of Hays, Kan., in January 2011 with deicing fluid that exceeded the maximum temperature of 180 degrees Fahrenheit. The Great Lakes deicing manual states that fluid heated to more than 180 degrees could damage the aircraft or the deicer.
