The Federal Aviation Administration said it's allowing sightseeing helicopters to descend through an airspace corridor over the Hudson River that's supposed to be off-limits to local air traffic.
The FAA barred helicopters and other aircraft from flying between 1,000 and 1,300 feet above sea level after a 2009 helicopter crash that killed nine people.
But the federal agency said it struck a deal with five tour companies in 2010, allowing them to pass through the air space near 79th Street in Manhattan.
An FAA spokesman said aeronautical charts do not warn other pilots about the exemption and that there are no plans to issue such a warning.
