Aviation safety reports, made easier to study

NTSB Reports is an independent research and search tool for public aviation accident and incident records. It brings NTSB aviation reports, structured fields, docket files, extracted figures, photos, videos, and update history into one searchable interface.

The goal is practical safety education: make it faster to find relevant investigations, compare similar events, review factual records, and understand the evidence behind probable-cause and preliminary reports.

The investigative work and source records belong to the National Transportation Safety Board and the published investigation record. This site is not affiliated with or endorsed by the NTSB.

The student pilot reported he was on a solo flight to a local gravel-covered airstrip. During the landing roll, he lost control of the tail wheel equipped airplane, and it ground looped/swerved to the left side of the runway. The right main landing gear collapsed, and the right wing struck the ground. The student pilot noted in his report to the NTSB that there were no preaccident mechanical problems with the airplane.

NTSB Probable Cause

The student pilot's inadvertent ground loop/swerve during the landing roll.

Full Narrative

On August 23, 1998, about 1600 Alaska daylight time, a wheel equipped Cessna 170A airplane, N9754A, sustained substantial damage while landing at the Bradley Sky Ranch airstrip, North Pole, Alaska. The solo student pilot was not injured. The 14 CFR Part 91 local instructional flight operated in visual meteorological conditions without a flight plan. The flight last departed Fairbanks International Airport on August 23, time unknown. FAA Fairbanks Flight Standards inspectors interviewed the pilot August 28. The FAA inspectors reported the pilot told them he was practicing landings in calm wind conditions at the Bradley Sky Ranch airstrip. The student pilot related that shortly after touchdown on runway 15, he lost directional control, the airplane ground looped/swerved to the left, and the right main landing gear collapsed. In the pilot's written statement to the NTSB, he reported a crosswind caught the left side of the airplane while landing, and pushed it off the right side of the runway, collapsing the right main landing gear, and striking the right wing on the ground. He did not indicate the estimated direction or velocity of the wind. At 1553, wind conditions at Fairbanks International Airport,16 miles west of the accident site, were reported to be from 124 degrees magnetic, at 8 knots. An inspection of the airplane by an FAA airworthiness inspector disclosed substantial damage to the right main landing gear's gear box, the bottom of the airplane's fuselage, and the aileron on the right wing. The pilot noted in his report to the NTSB that there was no preimpact mechanical malfunction with the airplane.
