The city is officially banning open-door helicopter flights from taking off within the five boroughs after last month's deadly helicopter crash.

The city's Economic Development Corporation (EDC) was expected to announce the new rule on Wednesday.

"It is our hope that by officially banning doors-off helicopter flights out of New York City, we will help improve air safety within the five boroughs," said NYCEDC President James Patchett. "We are thankful for the leadership and advocacy of the City Council on this important issue."

The new rule will not, however, affect helicopters that take off from New Jersey, like the one that crashed into the East River on March 11.

Five people died when they were unable to free themselves from their harnesses after the aircraft rolled over into the water. The pilot, who was not wearing a harness, escaped with only minor injuries.

"By calling for today's hearing of the Committee on Economic Development, we were hopeful that immediate positive safety changes would occur for helicopter aviation in the city," said Queens City Councilman Paul Vallone, the chair of the city's Economic Development Committee. "This agreement is very welcomed news and takes a huge step in the right direction."
