To ask the Secretary of State for Transport whether he has received evidence of aircraft engine testing which has confirmed the presence of organophosphates in the engine bleed air. (127360)

[holding answer 14 March 2007]: No. The Department for Transport (DFT) has asked the Department of Health (DH) to undertake an independent scientific review of data submitted by the British Airline Pilots Association (BALPA). BALPA submitted data relating to organophosphates, the cabin air environment, ill-health in aircraft crews and the possible relationship to smoke/fume events in aircraft. Consideration continues in the Committee on Toxicity of Chemicals in Food, Consumer Products and the Environment (COT). The next meeting of the COT is on 20 March 2007.

To ask the Secretary of State for Transport by what procedures pilots should report any contaminated air events on a UK registered commercial aircraft. (127361)

[holding answer 14 March 2007]: Pilots are required to report contaminated air events to the Civil Aviation Authority, where they meet the criteria for a Mandatory Occurrence Report. The definition of a reportable occurrence is contained in Article 142 of the Air Navigation Order.

In addition, airlines have their own reporting systems for non-mandatory occurrences for their pilots to follow.
