MANHATTAN - The National Transportation Safety Board (NTSB) is working to determine if equipment aboard the helicopter that crashed into the East River yesterday, killing a woman and injuring three other people, stored any useful information on what led to the crash.

"An aircraft like this could have something that records information, possibly GPS information," says NTSB member Mark Rosekind. "It wouldn't be standard for some kind of black box that you'd expect."

At around 3 p.m., the pilot of the Bell 206 aircraft reported problems just after taking off from Manhattan's East Side with four passengers aboard.

Australian tourist Sonia Marra was trapped and died when the chopper sank. Marra was in New York to celebrate her 40th birthday.

Rescuers were able to save her partner, her parents and the chopper pilot, Paul Dudley.

Dudley, who owns a home in Southampton, was not hurt in the crash and is cooperating with investigators.

Dudley is no stranger to emergency situations. In 2006, he landed a plane near Coney Island after engine failure.
