Seems I have touched a raw nerve on this subject…
Please can I respectfully ask on what you base your premise on for denying the existence of Toxic Air Syndrome? Are you in the aviation industry?
It is widely known that that air is taken in to the cabin via the Bleed Air intakes off the side of the engines (except on the Boeing 787). If engine oil leaks through the seals it contaminates the air. Engine oil contains a neuro-toxin (Tri-Crysl-Phosphate or TCP) which then attacks the body’s neuro system causing severe damage to cognitive responses, eg blinking, breathing, swallowing & decision making!
Many pilots I know do acknowledge the problem however find it difficult to get anybody in the industry to listen (CAA is now mainly funded by the airlines rather than the Government), Airlines do not want to admit to its existence as it lead to legal claims by both crews and passengers (Too late for Richard Westgate BA RIP), also the cost of either changing engine oils without the TCP or fitting of special air filters to aircraft. I spoke to a BA pilot about getting different oils used in the engines however he said that the engine manufacturer will not guarantee the engines without the TCP additive, so they are not co-operating. BALPA (pilots union) are being half hearted about the whole issue as they are concerned that thier members could be impacted by the airlines going bust if the issue is brought to the public conciousness. Other pilots I have spoken to as you say do not give a ‘second thought’ to it as they are concerned about rocking the boat & losing favour with their employers. Your statistic of 99.8% should be qualified, thus my challenge as to your industry.
Many pilots are most concerned but do not/cannot make it an isue!
Yet passengers as well as crew are bing potentially posioned every time they fly.
Some legal challenges have been successful including a cabin crew member who used to fly for Ansett (in administration) Australia and another by a cabin crew member who sued Boeing direct. (Please google them?). The Boeing case was settled out of court for an undisclosed sum and rigid caveats on disclosure.
A sure sign that the industry is rattled!
The awareness of this issues needs to be highlighted in order to change the dogmatic views of the aviation industry! (www.aerotoxic.org)
