NTSB Determines Cause of Collision

On June 29, 2008, two EMS Bell 407s collided midair during the approach to the Flagstaff Medical Center in Ariz. All seven people aboard the two helicopters died. The National Transportation Safety Board has determined that the probable cause was that both pilots' failed to see and avoid the other helicopter on approach to the helipad. Contributing to the accident were the failure of one of the pilots to follow arrival and noise abatement guidelines and the failure of the other pilot to follow communications guidelines. However, neither helicopter was equipped with a traffic collision avoidance system, nor was such a system required. If the system had been installed, it probably would have alerted the pilots to the traffic conflict so they could have avoided the crash. New FAA EMS regulations may change this policy.
