KODIAK, Alaska - Petty Officer 1st Class Andy Anderson, an aviation maintenance technician with Air Station Kodiak, reads through a check list for a rotor blade test that is done on MH-60 Jayhawk helicopters Sept. 23, 2010. The rotor test is to correctly check the balance of the blades and give maintenance personnel a finer focus to adjust the blade angles.
