JAKARTA, Indonesia -- A passenger plane carrying 27 people plunged into the ocean Saturday as it approached an airport in bad weather in Indonesia's eastern province of West Papua, killing at least 17, officials said.

Herry Bakti Singayuda, director general of air transportation, said the Chinese-made Xian MA60 twin turboprop plane went down just before landing in Kaimana. The flight, operated by state-owned Merpati Nusantara Airlines, originated in Sorong, another town in the province.

He said rescuers had recovered 17 bodies from the wreckage of the aircraft, which crashed into Kaimana Bay about 500 yards (meters) from the end of the runway. Searchers were hampered by heavy rain.

"Technically there was no problem with the plane," Singayuda told a news conference. He said the plane had only 615 flight hours and had been purchased in October. It was one of 13 MA60s currently used in Indonesia, he said.

Nuno Sampurno, chief of the National Search and Rescue Agency, said the crash was probably caused by bad weather which limited visibility.

Bambang Ervan, a spokesman for the transportation ministry, said it was unlikely that anyone survived.

"Given the condition of the wreckage of the ill-fated plane, it is hard to say that there are any survivors," Ervan said.

The passengers included an infant and two older children, Ervan said.

The Kompas newspaper said the plane was one of four MA60s owned by the airline.

Indonesia, an archipelago nation with more than 17,000 islands and 235 million people, has been plagued by a string of transportation accidents in recent years, from plane and train crashes to ferry sinkings. Overcrowding, aging infrastructure and poor safety standards are often to blame.
