Toxicology testing revealed diphenhydramine, an impairing medication that causes sedation, altered mood, and impaired cognitive and psychomotor performance in blood and urine specimens. Although the airplane's operating instructions called for the pilot to jettison the canopy before ditching, the pilot did not do so, and was subsequently unable to fully open the canopy and egress the airplane as it sank. Although the supercharger may have failed as the initiating event, the reason for the engine failure could not be determined due to the excessive internal damage to the engine.Įxamination of the pilot's seat belt/shoulder harness restraints and canopy operation, including a functional test of the jettison T-handle, did not reveal evidence of any in-flight anomaly or failure. ![]() Oil and metallic fragments were found inside the engine's supercharger. Damage to the inside of the crankcase prevented the removal of cylinders and disassembly of the engine. The pilot was unable to egress the airplane and drowned.Įxamination of the engine revealed evidence of internal seizure. Another pilot in the formation reported that the canopy was partially open before the ditching. The airplane landed on the water and subsequently sank. About 1,000 ft above the water, the pilot of the accident airplane made a distress call to air traffic control, stating that he had "smoke," and he subsequently ditched the airplane. ![]() The World War II-era fighter airplane was part of a three-ship formation performing a photo shoot.
