On August 5, 2005, about 1300 Alaska daylight time, a tailwheel equipped Aviat Husky A-1 airplane, N8XJ, sustained substantial damage when it nosed over during the landing roll at the Goose Bay Airport, about 8 miles north of Anchorage, Alaska. The airplane was being operated by the certificated flight instructor as a visual flight rules (VFR) instructional flight under Title14, CFR Part 91 when the accident occurred. The instructor and dual student were not injured. Visual meteorological conditions prevailed, and no flight plan was filed. The flight departed Lake Hood Strip, Anchorage, about 1145. During a telephone conversation with the National Transportation Safety Board (NTSB) investigator-in-charge (IIC) on August 5, the owner of the airplane said the instructor was giving tailwheel instruction, and practicing wheel landings when the dual student applied the brakes too heavily, and the airplane nosed over. The owner said the instructor reported damage to the wing leading edges, rudder and lift struts. The owner said there were no known mechanical anomalies with the airplane prior to the accident. The NTSB Form 6120.1 sent to the flight instructor was returned unclaimed.
