NTSB Narrative Summary Released at Completion of Accident
The pilot-owner of the amateur-built airplane completed an oil change and was seen performing other maintenance on his airplane. The airplane subsequently departed the uncontrolled airport at an unknown time, and was seen impacting an estuary, approximately 4 miles from the departure airport, after a near-vertical descent. The wreckage was highly fragmented. The engine, propeller, and several other components were not located or recovered. Examination of the recovered wreckage did not reveal any pre-impact failures. Toxicological tests on the pilot detected quinine (a medication used to treat malaria, found in tonic water, and available in non-prescription nutritional supplements marketed to reduce the frequency of nocturnal leg cramps) in the liver tissue. Side effects of quinine can include disturbances of vision, hearing, and balance, and the use of quinine by pilots is usually contraindicated, since it may contribute to spatial disorientation under some conditions. No information was obtained regarding the pilot’s possible use of quinine, and it was not possible to determine from the toxicology tests when the pilot might most recently have ingested quinine, or whether he may have been impaired by such use.
NTSB Probable Cause Narrative
An in-flight loss of control for undetermined reasons.
