Recent industry publications regarding the safety of EMS aviation operations are consistent with the Safety Board’s findings. For example, after an extensive 2-year safety review and risk assessment of helicopter EMS accidents, the Air Medical Physician Association (AMPA) reported in November 2002 that the time of day that flights occur could contribute to accidents.7 The report indicated that even though 38 percent of all helicopter EMS flights occur at night, 49 percent of accidents during a 20-year period occurred during nighttime hours. The report also cited controlled flight into terrain (CFIT), in particular during the takeoff or landing sequence, as a common problem, as well as collision with objects (wires were the most common obstacles for EMS helicopters); inaccurate weather forecasts (about 26 percent of helicopter EMS accidents were weather-related, with most occurring because of reduced visibility and IMC while the helicopter was en route); and communications problems with air traffic control (ATC) or a lack of communications due to remote locations and high terrain.
AMPA’s report also cited time pressures related to the patient’s condition, rapid mission preparation, flight to the patient pick-up location, and low fuel as frequent issues in EMS aircraft accidents. According to a query of the National Aeronautics and Space Administration’s Aviation Safety Reporting System, patient condition was cited in 44 percent of the EMS accidents or incidents reports as a contributor to time pressure leading to inaccurate or hurried preflight planning. In addition, the AMPA report stated that accidents occurred more often when flight crews were en route to pick up a patient than at any other time during flight. A white paper8 published by Helicopter Association International in August 2005 examined many of the same issues as AMPA.

“What an admirable training is science for the more active warfare of life! Indeed, the unchallenged bravery which these studies imply, is far more impressive than the trumpeted valor of the warrior.”
—Henry David Thoreau (1817–1862)
“[B]y going to the College [William and Mary] I shall get a more universal Acquaintance, which may hereafter be serviceable to me; and I suppose I can pursue my Studies in the Greek and Latin as well there as here, and likewise learn something of the Mathematics.”
