Probable cause

The pilot's failure to maintain adequate airspeed while maneuvering at low altitude, which resulted in the airplane exceeding its critical angle-of-attack and experiencing an aerodynamic stall. Contributing to the accident was the pilot's decision to make a steep turn at low altitude.

Findings · 4

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 and passenger were returning home after attending a fly-in at another airport. The passenger reported that, during the descent to land, the pilot spotted a boat on the lake that they were overflying and began to follow it at low altitude. The pilot then made a steep turn, which resulted in the airplane exceeding its critical angle-of-attack and experiencing an aerodynamic stall. The pilot then lost airplane control, and the airplane subsequently impacted the water. The pilot and passenger were rescued by nearby boaters. The airplane wreckage was not recovered from the water; neither the pilot nor passenger reported any anomalies with the airplane before the accident.

Factual narrative

On July 4, 2014, at 1405 central daylight time, a Slaughter CH601-HDS ultralight airplane, N4263, impacted Lake Palestine, Texas, near Frankston, Texas, while maneuvering at low altitude. The pilot was seriously injured and the passenger received minor injuries. The airplane was substantially damaged. 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 at the time of the accident, and no flight plan had been filed. The flight originated from Mineola Airport (3F9), Mineola, Texas, and was en route to Aero Estates Airpark (T25), Frankston, Texas. According to statements provided to FAA Inspectors and law enforcement officers, the pilot and his son were returning to T25 after attending a fly-in at 3F9. The son said that during their descent to T25, the pilot spotted a boat and began to follow it at low altitude. The pilot then made a steep turn and stalled the airplane, lost control, and impacted the water. The pilot and passenger were rescued by nearby boaters. The wreckage remained in the lake and was not available for examination. Neither occupant indicated there were any system malfunctions with the airplane prior to the accident and indicated fuel exhaustion did not occur.
