Analysis

The pilot of the amateur-built Dakota Hawk DH23 had just landed and had slowed the airplane to about 20 mph during the rollout when the right main landing gear collapsed rearward. The airplane ground-looped, and the right wing impacted the pavement. A subsequent Federal Aviation Administration examination of the airplane revealed that the landing gear tubing, under a flange in an area that was difficult to see, appeared to have been cracked prior to the accident. The airplane was manufactured in 2006 and had 90 hours of operation.
