A police sweep of residential areas Saturday in the city of Fukuoka found some 600 metal fragments believed to be from a Japan Airlines group jetliner that saw one of its three engines burst into flames after takeoff the night before.
After the engine trouble, the Honolulu-bound DC-10 operated by low-cost carrier JALways returned to Fukuoka Airport.
The Land, Infrastructure and Transport Ministry had warned airlines of the possibility of an accident resulting from damage in that type of turbofan engine, according to industry sources.
