Probable cause
The pilot’s improper landing flare, which resulted in failure of the right main landing gear and a subsequent loss of control.
Findings · 3
NTSB’s coded findings. Those marked are part of the probable cause; the rest are factors or other findings. Under each, the cases with the same finding.
Sequence of events
The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.
Analysis
The pilot stated that the final approach and touchdown were uneventful, but then the airplane's right wing “dipped,” the nose veered left, and the airplane departed the runway surface. Witnesses reported that, during the landing, the nose gear contacted the runway first and then the airplane became airborne again. After the second touchdown, the airplane veered left into the grass. Examination of the airplane revealed that the right main landing gear sustained damage consistent with an excessive side load during landing. There was no evidence of a preimpact mechanical malfunction that would have precluded normal operation. Based on the available information, the accident is consistent with the pilot’s improper landing flare, which resulted in touchdown on the runway with a side load on the landing gear, failure of the right main gear, and a loss of control.
Factual narrative
On June 24, 2019, about 1025 mountain daylight time, a Piper PA-24 airplane, N5866P, was substantially damaged when it was involved in an accident near Greeley, Colorado. The private pilot and passenger were not injured. The airplane was operated as a Title 14 Code of Federal Regulations Part 91 personal flight. The pilot reported that he completed a touch-and-go landing, which was uneventful, and he planned his next landing to be a full-stop landing. The pilot stated everything "was good" until touching down, when the airplane's right wing “dipped” and the nose veered left, causing the airplane to exit the runway surface. The airplane hit a taxiway light and continued into the grass on the south side of the runway, where it came to rest. A flight instructor who witnessed the accident stated that, during the landing, the nose landing gear hit the runway first and the airplane bounced and became airborne again before he lost sight of it. Examination of the airplane revealed that the side brace stud of the right main gear side brace upper link assembly was disconnected from the main gear side brace support fitting assembly. The roll pin inserted through the threading on the stud that connected to the support fitting was sheared and the threads of the stud were stripped. The push/pull (conduit) cable assembly arm that connected to the main gear side brace upper link assembly and actuated the landing gear was bent upward. No mechanical anomalies that would have precluded normal operation of the landing gear were found.
