SINGAPORE — Investigators scouring the Indian Ocean for traces of the Malaysian Airline System jet that disappeared March 8 will announce a new search area by the end of this month.

A group including investigators from the United States, Britain and Australia and representatives of Boeing and Inmarsat has been analyzing satellite and plane data “to arrive at a consensus on the area that offers the highest probability of finding the missing aircraft,” Australia’s Joint Agency Coordination Centre said in an emailed response to questions from Bloomberg News Wednesday.

“That work is nearly complete and the revised search area, as agreed by the specialists, is expected to be announced before the end of June,” according to the email.

The defined area will help focus the longest search operation in passenger aviation history, as Australia prepares to hire a private company to scour the ocean. No trace of the Boeing 777-200 with 239 passengers and crew aboard has been found since flight MH370 vanished more than three months ago, and communications with an Inmarsat orbiter remain the only clues to its location.
