THE RECENTLY CERTIFICATED 200-POUND PILOT AND HIS 190-POUND PASSENGER LANDED WITHOUT DIFFICULTY AT A 4000-FOOT MSL SITE. ABOUT 15 MINUTES LATER, WITH AN AIR TEMPERATURE OF 92 DEGREES F, THE PILOT AND PASSENGER ATTEMPTED TO TAKEOFF. THE HELICOPTER CLIMBED 30 FEET ABOVE THE GROUND AND THEN LOST ROTOR RPM. THE PILOT LOST CONTROL AND DESCENDED INTO TREES. THE COMPUTED DENSITY ALTITUDE WAS APPROXIMATELY 6950 FEET.
Probable Cause: THE PILOT'S FAILURE TO MAINTAIN ADEQUATE ROTOR RPM DURING AN ATTEMPTED TAKEOFF. A CONTRIBUTING FACTOR WAS THE HIGH DENSITY ALTITUDE.
