(CNN) The National Transportation Safety Board on Monday released a preliminary report on a deadly helicopter crash in New York's East River . "The information in the report is preliminary and subject to change as the NTSB's investigation progresses," the NTSB said. The pilot told NTSB investigators he provided a safety briefing to the passengers before takeoff. An NTSB examination of the helicopter found the engine was not impacted by "oil or fuel leaks, fire, or uncontainment," according to the report. But NTSB Chairman Robert L. Sumwalt said "the FAA has not outlined how or when they plan to take action."
