Excerpt from FAA NOTICE N 8000.301
A preliminary review of the commercial HEMS accidents from January 1998 through December 2004 revealed that
•CONTROLLED FLIGHT INTO TERRAIN (CFIT),
•INADVERTENT FLIGHT INTO INSTRUMENT METEOROLOGICAL CONDITIONS (IMC), AND
•LACK OF OPERATIONAL CONTROL
are predominant factors, particularly at night and during low visibility conditions.
Excerpt from FAA NOTICE N 8000.301Continued
Of the 27 fatal HEMS accidents, 21 occurred during night operations. Of the 21 night accidents, 16 of the operations originated under visual flight rules (VFR); the pilots inadvertently flew into IMC conditions, resulting in a CFIT accident.
