When a helicopter crashes, the wreckage can leave a trail of clues that leads all the way back to the aircraft's design and manufacturer. In 2012, civil helicopters flew more than 3 million hours in the United States, resulting in 153 accidents. Of that number, 22 were fatal and 23 resulted in serious injuries. Prompt investigation of the crash site and knowledge about common causes of these crashes are critical. Abraham Watkins has handled many aviation cases through the years.
