A Spirit Airlines Airbus A319-100, registration N531NK performing flight NK-424 from Los Angeles,CA to Minneapolis,MN (USA), was enroute at FL330 about 230nm northeast of Las Vegas,NV (USA) when the crew decided to turn around and divert to Las Vegas reporting smoke in the cockpit. The aircraft landed safely on Las Vegas' runway 26R about 40 minutes later.

The FAA reported three flight attendants were transported to a hospital with unknown injuries.

On Mar 12th 2019 The Aviation Herald was informed that shortly after the occurrence one of the affected cabin crew members suffered cerebral haemorrhage, a stroke resulting in hemiplegia as well as additional nerve damage. Laboratory results suggest a critically low value of cholinesterase enzymes (neurotransmitters). A preliminary scientific assessment suggests a causal link between the smoke event and the health issue. After verifying the documents The Aviation Herald inquired with the NTSB on Mar 17th 2019, stating the information as portrayed above, about whether the occurrence is being investigated by the NTSB. On Mar 21st 2019 the NTSB responded: "At this time, we are not investigating. I will update if that changes."

In 1989 the FAA had released a paper by FAA's AAM, the FAA's Aeromedical Research Institute, produced in 1963 under the title "Central Nervous System Effects of chronic exposure to organophosphate insecticides" stating in the discussion on page 4 amongst others: "It is commonly accepted that the toxic actions of the organophosphate pesticides result from their inhibition of the cholinesterase enzyme. Unlike the carbamates and a variety of other chemicals and drugs which exert a temporary or transient effect on the activity of this enzyme, the organophosphates exert a persistent action because of the formation of a chemical bond between the phosphorus-containing radical and a receptor site on the enzyme itself."
