Hours after the crash, emergency crews still swarmed around the plane's cockpit.

At first, the airline said everyone survived. But at a news conference later, Michel Bezuijen, acting mayor of Haarlemmermeer, reported the fatalities.

"At this moment there are nine victims to mourn and more than 50 injured," he said. At least 25 of the injured were in serious condition and crew members were among the injured.

He said there was no immediate word on the cause of the crash.

The Turkish ambassador to the Netherlands, Selahattin Alpar, told the Anatolia news agency there were 72 Turks and 32 Dutch people on board. There was no information on the nationality of other passengers.

Candan Karlitekin, the head of the airline's board of directors, told reporters that visibility was good at the time of landing.

"Visibility was clear and around 5,000 yards (4,500 meters). Some 550 yards (500 meters) before landing; the plane landed on a field instead of the runway," he said.

"We have checked the plane's documents and there is no problem concerning maintenance," he added.

Turkish Airlines CEO Temel Kotil said the captain, Hasan Tahsin, was very experienced and a former air force pilot. Turkish officials said the plane was built in 2002 and last underwent a thorough maintenance on Dec. 22.

Gideon Evers, spokesman of the International Federation of Airline Pilots Associations, said the cause of the crash remained unclear. There was no indication that the crash had anything to do with fuel levels, Evers said, adding that regulations require all commercial flights to carry ample reserves.
