Read the full NTSB narrative

The scheduled commuter flight had been en route for approximately 30 minutes and was in cruise flight at 13,000 feet MSL. Both pilots complained of dizziness and disorientation. After going on oxygen the symptoms dissipated and a normal landing was made at the intended destination approximately 10 minutes after the occurrence. Examination of the aircraft, crew, luggage, and cargo provided no evidence of a problem and neither crew member had any physical manifestations such as smell or irritation. One passenger indicated the possibility of dizziness. No other aircraft in the area at the time reported any difficulty. A test flight was conducted using the same crew, aircraft, route, and altitude. During the flight, tests were performed by a industrial hygienist with negative results. Tracking of the crew and aircraft for several months provided no additional insight.
