Britten-Norman BN-2A N906GD accident near Ceiba, Puerto Rico

Probable cause

The pilot’s loss of consciousness during taxi for reasons that could not be determined based on the available information.

NTSB analysis

The airline transport pilot was taxiing the airplane for takeoff for the on-demand air taxi commuter flight. The pilot reported that, while taxiing to the runway, he felt dizzy and lost consciousness. The airplane subsequently veered off the taxiway into a ditch with the engines were still running. The pilot shut down the engines and instructed the passengers to exit the airplane.

The pilot reported that it was hot and that he hadn't eaten breakfast before the accident flight; however, neither of these things should have caused the pilot to lose consciousness without other health issues involved. A review of the pilot's medical history revealed no evidence that he was taking any medications or that he had visited health care providers for any medical issues. The reason that the pilot lost consciousness could not be determined based on the available information.
