Since 1954, Boeing, the leading manufacturer of commercial airplanes, has used a "bleed air system" for cabin air in most of its planes. This means that the air breathed by passengers and the flight crew comes from the outside, then through the heated jet engines and into the cabin. If the jet engine leaks oil (for one of a number of reasons), the toxic by-products of that oil get into the cabin air system. These are known as “fume events,” and studies estimate that one fume event occurs every day. These events can be very dangerous to the health of passengers and crew members, causing both short and long-term injuries.  If you or a loved one have been injured in a fume event, you can contact Leckman Law for a free evaluation of your case.
