1.   At those altitudes, the temperature was probably below freezing, and rain was heavy at the time, conditions that can lead to ice buildup.

2.   All ATR aircraft wings have since been modified to better protect against ice buildup.

3.   But it did not say that an ice buildup could make an aileron pop up, leading to a sudden roll.

4.   But three experts in accident investigation who are not working on this crash said that uncommanded rolls can be caused by ice buildup.

5.   In those tests, unusually shaped mockups of ice buildup were placed on the wing and were found to disrupt roll control.

6.   It is vulnerable to sudden temperature swings, ice buildup, water torrents and acid rain, and over time even corrosion-resistant metals can succumb.

7.   Just three weeks after the crash, safety board officials said ice buildup on the wings was a major contributor.

8.   Now I am getting a lot of ice buildup on the edge of the roof.

9.   Should I take off the gutters to prevent the ice dam buildup?

10.   Subsequent ice buildup at drip edges and in gutters creates dams that cause water to back up under shingles and sometimes cascade into attics and down walls.
