4.55 In evidence to the inquiry the Ansett Pilots Association expressed strong support for the actions taken by Ansett to deal with the problem of fumes on the BAe
146. Mr Michael Egan of the Association stated:
… based on the reports that we have received from our members who operate the British Aerospace 146 aircraft, that the actions that Ansett Australia has taken to improve the quality of air provided to the cabin and cockpit of the aircraft have been very successful. Over recent months, we have received no complaints of fumes in the cabins or cockpits of British Aerospace 146 aircraft. On questioning crews, we have been informed that mild cabin smells have been noticed on a small number of flights and that the aircraft in question has had engineering attention at the first available moment to investigate the source of the odour. These odour occurrences generally appear to be related to the efficiency of the cabin air filtration systems fitted by Ansett Australia. As noted in the Queensland Government Health Department report, these filters are very efficient at reducing contaminants and it becomes difficult to relate a smell event to an engine event. Apart from a major component failure, such as a bearing seal failure that will overcome the filters, the filters provide a significant safety circuit. The completion of the aircraft modifications and the current continuing monitoring of the aircraft air quality seems to be keeping occurrences of contamination of cabin air on the 146 Ansett Australia aircraft to a minimum.54
4.56 Mr Egan later went on to comment:
It would appear that the unmodified British Aerospace 146 seemed susceptible to poorer than normal air quality and that this air appeared to contain a number of contaminants that affected to varying degrees the crew and passengers that they carried. The Ansett Pilots Association believes that the modifications that Ansett Australia has carried out on its British Aerospace 146 aircraft and the ongoing preventive and reactionary maintenance program that Ansett Australia has put into place has significantly reduced the frequency and severity of cabin odours in these aircraft. 55

I think Ansett has been very good about this whole issue. They have investigated a number of different ways of handling the problem. They have looked for pilot input into better ways of operating the aeroplane that may not cause fume smells. They have always been interested in reports of any occasion when there is a smell. I think they have been very proactive. 56
Actions taken by Qantas and National Jet Systems Pty Ltd
4.57 According to National Jet Systems Pty Ltd maintenance and operating procedures have been developed in concert with British Aerospace to enhance the quality of the cabin air in the BAe 146. These initiatives included:
