2.37 The Committee received evidence of continuing health problems since December 1998 experienced by flight crew allegedly exposed to fumes both prior to and after completion of the modification programs.35
2.38 In addition, the Committee has received submissions from several flight attendants employed by Ansett and seven pilots employed by a number of operators reporting health effects from fume contamination.36 This number appears additional to a first officer mentioned by Dr David Lewis of Ansett Australia.37
International experience
2.39 Dr Jean Christophe Balouet in his submission noted:
It is estimated that about 70 major smoke/haze events, no fire but cabin air contamination by aircraft fluid leaks, occur world wide annually (with 25 to 30 for the commercial aviation in the USA) and that the number of severe fume events is over 500 annually (40 000 passengers and crew). Alaska airlines have filed over 1000 complaint flights in the past ten years. In Canada, over 600 complaint reports have been filed for the past 5 years. Over 30 legal cases are censused [sic] world wide.
Some aircraft types, especially BAe 146, MD 80, B 737, A 300, and a limited number of companies (ANSETT/NJS, Alaska Airlines, Air BC, Canadian operating these aircraft) have been the cause of over 90 % of the world wide problems identified today, whereas they represent less than 3% of world flights. …
Ansett NJS and BAe 146 are statistically the highest ranking for cabin air problems, before Alaska.38
2.40 In evidence to the inquiry Dr Balouet said:
If you have at Ansett and NJS one leak in every 160 aircraft flights, that is probably one of the poorest statistics around the world. In 1992 the statistics for Ansett was one flight with an odour every 66 flights, and one flight leaking for every 160 flights. … Eight hundred reports in eight years time is basically 100 reports per year. Alaskan Airlines, which is another company with a high number of very significant problems has a fleet which is about three times the size of Ansett plus NJS and they only have 100 reports per year.
… statistically it certainly is Ansett that ranks first.39
