Australia will ban older and noisy aircraft from the country's major airports from 1 September, as it seeks to reduce the impact of aircraft noise on homes.
Under the new law, the Boeing 727-100, 727-200, DC86 and Antonov An-124 will be disallowed.
Classified as "marginally noise-compliant" jets, they are mostly used in the air freight industry and are "an ongoing source of concern for residents around Sydney, Melbourne, Brisbane and Perth airports", says Australia's transport minister Anthony Albanese.
"These aircraft were certified to operate following modifications to meet aircraft noise standards issued in the 1970s. Most have been fitted with 'hush kits' which entitles them to a 'marginally compliant' rating under the 1977 regulation," he adds.
The ban on the aircraft will be phased in at Australia's airports.
From 1 July, no new services using such aircraft will be allowed at Sydney, Brisbane, Melbourne, Perth, Adelaide, Hobart, Darwin, Cairns, Gold Coast, Essendon, Newcastle, Avalon and Canberra airports.
From 1 September, all existing services operated with such aircraft must cease at Sydney, Brisbane, Melbourne and Perth airports, says Albanese.
Such aircraft make an average of 620 movements to and from the four airports every year, he adds.
The new law, however, allows for such aircraft to operate in cases of emergency and "in limited cases, where a flight is in the public interest", says Albanese.
