The Australian Government has said it will ban old and noisy freight jets operating out of major airports as part of an initiative to minimise the impact of aircraft noise over densely populated areas.
The new regulation, which was first projected in an aviation Green Paper published in December 2008, will be effective from 1 September 2010.
Under the new regulation, all existing services of older jets such as Boeing 727s will be banned at Sydney, Brisbane, Melbourne and Perth.
From 1 July 2010, no new services using these aircraft will be allowed at Sydney, Brisbane, Melbourne, Perth, Adelaide, Hobart, Darwin, Cairns, Gold Coast, Essendon, Newcastle (Williamtown), Avalon and Canberra airports.
The new regulation, however, has kept a provision that will allow a marginally compliant aircraft to operate in the event of an emergency.
The transport ministry has advised airports and airfreight operators to implement the new regulation by 1 July.
