Analysis

The pilot said he made a wheel landing on runway 17 with a crosswind from the left at 5 knots, gusting to 12 knots. He said that during the landing, the right main landing gear collapsed. An inspection of the airplane after the accident revealed no preexisting anomaly, and the right main gear collapsed from what appeared to be a side load.

Factual narrative

On July 19, 1997, at 1030 central daylight time, a Weatherly 201C, N9054W, operated by a commercial pilot, sustained substantial damage during rollout on landing on runway 17 (2700' x 60' dry/asphalt) near Stephen, Minnesota. The 14 CFR Part 137 aerial application flight was operating in visual meteorological conditions. No flight plan was on file. The local flight departed at 1000.

The pilot said that he made a wheel landing and that during rollout the right main landing gear collapsed. He said that there was a crosswind from 110 degrees at 5 knots with gusts to 12 knots.

An inspector from the Federal Aviation Administration said that he inspected the airplane and found no preexisting anomalies with the airplane. He stated that the failure appeared to him to be from a side load applied to the landing gear.
