Analysis
On June 12, 2005, about 1030 Alaska daylight time, a Cessna 170B, N2830C, sustained substantial damage when it ground-looped following a loss of control during landing at Merrill Field, Anchorage, Alaska. The airplane was being operated by the pilot as a visual flight rules (VFR) personal local flight under Title 14, CFR Part 91, when the accident occurred. The private pilot and passenger were not injured. Visual meteorological conditions prevailed, and a VFR flight plan was filed.
During a telephone conversation with the National Transportation Safety Board (NTSB) investigator-in-charge (IIC) on June 6, the pilot said he landed on runway 06. He said the Automatic Terminal Information Service (ATIS) was reporting the wind from 040 degrees at 6 knots, but he thought it was more of a direct crosswind, and gusting. The official weather observation for Merrill Field at 1030 reported the wind was from 030 degrees at 9 knots. The pilot said that during the landing roll, the left wing lifted, and he lost directional control. The airplane ground-looped to the left, and the right main landing gear collapsed. The airplane sustained damage to the propeller, main landing gear, fuselage, and left wing.
