This rulemaking would extend the expiration date of the final rule requiring pilots operating civil helicopters to use the New York North Shore Helicopter Route when operating along the north shore of Long Island, New York, for 2years until August 6, 2016. The purpose of the rule is to protect and enhance public welfare by maximizing utilization of the existing route flown by helicopter traffic 1 mile off the north shore of Long Island and thereby reducing helicopter overflights and attendant noise disturbance over nearby communities.
