A WING from an aircraft, suspected to be from MH370, is being analysed by the Australian Government, officials have confirmed.

Australian Infrastructure and Transport Minister Darren Chester said the wing part was found on Pemba Island off the coast of Tanzania.

He said the aircraft part had arrived in Australia and was currently being examined at the Australian Transport Safety Bureau.

He said experts from Malaysia and Australia were analysing the part at the bureau's labs in Canberra.

Malaysia Airlines flight MH370 disappeared on March 8 2014 when it was en route from Kuala Lumpur to Beijing. A total 239 passengers and crew were on board.

It is believed the plane plummeted into the Indian Ocean and authorities have been searching underwater for the missing plane.

In the latest search update this month, officials said poor weather conditions had severely impacted search operations and resulted in six to eight week delays in search operations.

Deep tow equipment can be used to search the ocean in marginal weather conditions but an underwater vehicle, which is used to survey some of the most difficult parts of the search area including underwater canyon areas, can only be launched in calmer conditions in spring and summer.

More than 110,000 square kilometres of the seafloor has been searched so far. The target is to search 120,000 square kilometres.
