NTSB Chairman Deborah A. P. Hersman testified today on the status of the ongoing investigation into the mid-air collision over the Hudson River. The collision occurred on August 8 between a helicopter and an airplane. All 9 persons on board both aircraft were killed.
Chairman Hersman provided an overview of the ongoing investigation based on facts that have been identified to date. The testimony did not provide any analysis or conclusions on what may have caused the accident.
At the hearing before the Subcommittee on Aviation on Transportation and Infrastructure, Hersman noted that the Safety Board has identified some areas of concern that have prompted the Board to issue safety recommendations early in its investigation.
"We issued early recommendations prior to the conclusion of our investigation because this accident demonstrated that there is a need for new procedures to be put in place to minimize the risk of collision," said Chairman Hersman. "The Federal Aviation Administration has taken quick action to address operational changes in the Hudson corridor. We are reviewing their proposal to determine if it meets the intent of our recommendations."
Also during her testimony, Chairman Hersman presented an animation depicting the accident sequence. The animation was created based on radar data and audio from Air Traffic Control communications.
