The crash occurred about 6:30 a.m., only a few miles from the Van Sant Airport, which is owned by the Bucks County Airport Authority.
But officials said they are not certain where the helicopter's flight originated. It appears it took off from private property, not an airport.
A number of witnesses reported hearing a loud explosion near Uhlerstown Road and Everbreeze Drive. Then they saw flames.
It was unclear if the pilot was still with the aircraft when it went down. The helicopter was mostly destroyed.
Jim Peters, a spokesman for the Federal Aviation Administration, said it has been difficult for investigators to get information on the aircraft since the tail was so badly burned.
"We don't know how many people were on board the helicopter," Peters said.
The National Transportation Safety Board will assume responsibility for investigating the crash, he said.
The helicopter likely did not have to file a flight plan, according to Peters, so information about the route or purpose of the flight was not immediately available.
The FAA requires all aircraft to be registered and that number is placed on the tail.
It's most likely that the helicopter was flying under visual flight rules, which operate under certain conditions such as clear, bright days.
"Our information is very preliminary and subject to change," Peters said.
