A senior official at Indonesia's National Search and Rescue Agency (Basarnas) Friday said the operation to lift the tail of the crashed AirAsia plane was hindered by heavy weather.
"The efforts are yet to succeed due to strong undersea stream and low visibility suffered by the divers as weather has changed fiercely at the location," Director of Operation and Training of Basarna, S.B. Supriyadi told Xinhua news agency over phone.
He said that the military team tasked to lift up parts of the plane's wreckage found that sands and mud has poured into the wreckage, making parts planned to be lifted up heavier than initial calculations by the team.
"The weight of the parts we planned to lift up has increased from 10 to 30 tonnes. Now the team is making new calculations to ensure the success of its operation," Supriyadi said.
The Indonesian military has prepared a crane with a lifting capacity of 70 tonnes and huge balloons to facilitate the operation.
The official said that the operation to lift the tail would resume Saturday should the weather be favourable to the mission. The search for the black boxes has been declared as priority of the operation.
