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

Shortly after takeoff, the pilot felt a vibration in the airplane’s controls and elected to return to the departure airport for a precautionary landing. While on short final, the airplane impacted a fence then made a hard landing on the runway. During the landing, the main landing gear was pushed up through the wing and the nose gear collapsed. The airplane subsequently exited the runway before coming to rest in an upright position. A postaccident examination of the airplane revealed that the bolt holding the rudder trim tab to the actuator connecting rod was missing. The absence of this bolt would have allowed the trim tab to swing freely on its hinge. The pilot reported that during the preflight inspection, he observed that the rudder trim system was inoperative. Unable to center the rudder trim tab, the pilot elected to remove the bolt before takeoff. The pilot further reported that he was planning to have the trim system repaired when he returned his home base.

Factual narrative

On August 22, 2011, about 1600 central daylight time, a Piper Aerostar 601P, N8076J, experienced a vibration after takeoff from the Alpine-Casparis Municipal Airport (E38), Alpine, Texas. Following a return to the airport, the airplane experienced a hard landing and sustained substantial damage to both wings. The private pilot, a second pilot, and the sole passenger were not injured. The airplane was registered to and operated by the pilot under the provisions of 14 Code of Federal Regulations Part 91 as a personal flight. Visual meteorological conditions prevailed and an instrument flight rules flight plan had been filed for the cross-country flight destined for the Houston Southwest Airport (AXH), Houston, Texas. The pilot reported that after takeoff he felt a vibration in the airplane’s controls. The pilot elected to return to the departure airport for a precautionary landing. While on short final the airplane impacted a fence followed by a hard landing to the runway. During landing both main landing gear were pushed through the upper wing skins and the nose gear collapsed. The airplane subsequently exited the runway before coming to rest in an upright position. A post accident examination of the airplane revealed that the bolt holding the rudder trim tab to the actuator connecting rod was missing. The absence of this bolt would allow the trim tab to swing freely on its hinge. According to a Federal Aviation Administration (FAA) inspector, the pilot informed him that during the preflight inspection he observed that the rudder trim system was inoperative. Unable to center the rudder trim tab, the pilot elected to remove the bolt before takeoff. The pilot further reported that he was planning to have the trim system repaired back at his home base.
