 Avro 146-RJ100, HB-IXN, Flight LX1103, Approach to Zurich-Kloten Airport, 19 April 2005
“The aircraft was released for flight operations several times, even though the defect had not been rectified.” “The copilot was limited in his capability of acting during the approach and landing due to the effects of fumes.” “The medical examination of the copilot after the flight showed that during the flight toxic exposure took place.”

“Cause: The serious incident is attributable to the fact that on approach to Zurich Airport the cockpit filled with fumes which caused a toxic effect, leading to a limited capability of acting of the copilot. These fumes were caused by an oil leak …”

Aerotoxic Association Comment: It is significant that the Swiss Air Accident Investigation Bureau have acknowledged the TOXIC effects of cabin air contaminated by engine oil. Other reports have usually described these fumes as an “irritant” only".
