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

During a local sightseeing flight, the pilot descended through an altitude of 1,000 feet to be able to see a waterway below him. As the pilot performed the low flight maneuver, the airplane impacted a power line, causing the vertical stabilizer to separate from the airplane. The pilot reported experiencing resistance and a vibration with the airplane, followed by a loss of control. He was able to subsequently perform a forced landing straight ahead, during which the airplane sustained damage to the nose gear and to the rudder. A witness stated that he heard a low flying airplane, followed by a loud noise similar to a "pop," and then he observed the airplane dragging a cable. Examination of the accident site by a Federal Aviation Administration inspector, revealed the vertical stabilizer, with 150 feet of power line still attached. It was located approximately 300 feet aft of the wreckage. No pre-impact malfunctions were reported by the pilot or identified during the post-accident examination.
