Paris/Johannesburg  - Searchers have recovered the second flight recorder from the Yemenia Airways plane which crashed in the Indian Ocean two months ago, killing 152 people, officials said Saturday.

The cockpit voice recorder was recovered off the Comoros Islands, a day after the flight data recorder was retrieved. Both pieces of equipment will be sent to France for analysis, the team investigating the accident said.

Experts hope the data will provide clues as to what caused the accident, in which a teenage girl was the only survivor.

The flight data recorder, which stores technical information about the plane's operation, was first detected from signals it emitted a few days after the June 30 crash.

But the recorder - also often referred to as the black box - was difficult to pinpoint at a depth of 1,200 metres and its recovery was extremely difficult, officials said.

The Airbus A310 plane, en route from Yemen to Moroni, the capital of the Comoros Islands, went down about 10 kilometres offshore in the early hours of June 30.

Most of the passengers were natives of the Comoros or French nationals on their way to visit relatives on the islands.(dpa)
