PITTSBURGH – A federal judge has denied a request for entry of default judgment from a pilot who worked for a California airline and allegedly suffered sustained negligent and prolonged carbon monoxide exposure in the planes he was flying. Jeremy Ravotti of Leechburg first filed suit in the U.S. District Court for the Western District of Pennsylvania on Nov. 28, 2018 versus OneJet, Inc. of Larkspur, Calif. The suit concerns the airplanes’ allegedly defective “bleed air” system, one that regulates the air entering the cabin and cockpit after making contact with the plane’s engines. It can become contaminated with heated jet engine oil and toxic byproducts, increase the temperature throughout the airplane and produce fumes having a “dirty” or “wet sock” smell.
