3 Passengers on SkyWest Airlines Flight Lose Consciousness

[Tywais]

Three passengers on a SkyWest Airlines flight Wednesday reported a loss of consciousness, the airline said.

SkyWest Airlines Flight 5622 -- operating as United Express -- made an unscheduled landing in Buffalo because of the passengers losing consciousness. The passengers were evaluated after the plane landed, and the flight later arrived at its intended destination of Hartford, Connecticut.

The passengers who reported a loss of consciousness were not hospitalized, the airline said in a news release.

Vanessa Bergmann, a resident of Amherst, Massachusetts, said passengers on the flight were concerned after the pilot plunged the plane nearly 30,000 feet in a matter of minutes.

“We leveled out at 10,000 feet, and that was pretty darn scary,” Bergmann said after the plane landed.

SkyWest Airlines is continuing to investigate the matter -- but the airline says there are no indications of a pressurization problem on the plane.

Gases from the engine providing the pressurization to the cabin - oil or hydraulic fluid in the bleed air from the engine into the cabin?

A "fume event"?

More like a strange event. Reading another source, only people in a few rows were effected as well as a nurse that was there trying to help. What ever it was, very strange to be so isolated to such a small area.

Aircraft Engine Bleed Air and Air Conditioning 101. The air used to provide pressurization for the cabin is Bleed Air for either 8th or 13th Stage of Compression in the engine, depending on power setting of the engine. Occasionally one of the Air Oil Seals will allow a small amount of oil vapor to enter the compressor section.

The Pressurized air from the engine goes through two Heat Exchangers , a Primary before entering the Air Cycle Machines which is both a compressor and then an Expansion Turbine, there is a Secondary Heat Exchanger between the Compressor side of the ACM and the Expansion Turbine side. The expansion of air is where the cooling comes from. It then goes through a Coalescing Filter to remove any particulate matter and oil vapors.

Someyimes some oil fumes will enter the cabin, but you can smell it and the crew can isolate the bad system and shut it down. It would be very rare to have the fumes in only one isolated area as the air enters a Plenum Chamber and the distribution is wide spread from there. The only isolated place could be where the Risers are located carrying air to tghe overhead bins and Gasper Outlets. That row is where you only have one window instead of two for each seat.

.Now we wait and see what the findings are.
