The Federal Aviation Administration is proposing stricter flight rules for helicopters, including requiring all craft be equipped with an electronic system that warns of terrain or other obstacles.
The proposals were released Thursday.
The FAA says helicopter crashes are on the rise. In 2008, six accidents involving medical helicopters killed 24 people in the deadliest year recorded.
Since the mid-1990s, more than 200 people have died in accidents involving commercial helicopters or helicopter air ambulances.
A crash in Arkansas in August killed a pilot, flight nurse and flight paramedic.
Among the FAA's proposals are a rest requirements and flight time limitations for flight crews operating with medical personnel on board.
