On October 27, 1998, about 1400 eastern standard time, a Cessna 152, N48875, registered to the U. S. Navy and operated by the Atlanta Navy Flying Club, collided with a parked aircraft when the pilot lost directional control during landing roll, while on a Title 14 CFR Part 91 instructional flight. Visual meteorological conditions prevailed at the time and a visual flight rules flight plan was filed. The aircraft received substantial damage and the student-rated pilot was not injured. The flight originated from Naval Air Station Atlanta, the same day, about 1330. The student stated that landing flare and touchdown were normal. During landing roll the aircraft started moving to the left and he lost total control, even when he applied right rudder. He stated he was distracted by raising the wing flaps and was slow to apply the right rudder. He stated he also continued to hold aft pressure on the control wheel. The aircraft ran off the left side of the runway, crossed over a taxiway in front of a taxing aircraft, and collided with a parked aircraft on the parking ramp.
