After rescuers found a child survivor who was pulled alive from the sea, the cause of the crash of an Yemeni jetliner with more than 150 people on board off Comoran coasts remains elusive.

The jetliner, an Airbus A310, crashed early Tuesday into the Indian Ocean as it approached the airport on the Comoros islands in heavy winds and bad weather. The plane was carrying 153 people -- 142 passengers and a crew of 11.

France's Transport Minister Dominique Bussereau said on Europe 1 radio Tuesday that the plane was "not at fault" in the crash. "It has nothing to do with the plane."

However, the minister also pointed out that the jet had been found to have "faults" in a 2007 inspection.

Bussereau told France's i-Tele television that the Airbus A310 was inspected by France's civil aviation agency DGAC in 2007, and "they noticed a certain number of faults."

Those failings, the minister said, had been pointed out to the company by the French authorities and by coincidence, this plane had never reappeared in European airports since then.
