This Is Wrong.

Several published reports show that ice can accumulate on the main rotor without any detectable ice on the fuselage. The following is one example:
Two helicopters flew below clouds for a short time. The lead helicopter had a two-man crew and, for this reason, could maintain lower altitude than the second (the non-flying crew member kept a sharp lookout for wires). However, the alti-tude difference was only a few meters, with the second heli-copter following closely behind and above the lead aircraft. The flight proceeded close to the cloud base.
At one point, when the pilot of the lead helicopter had to slow down, the second pilot found that he did not have sufficient power to maintain altitude and made an emergency landing. The same maneuver had been made a moment earlier without any problem. No vibrations were felt during the flight. Two to three minutes after the second helicopter had landed, the lead aircraft had to make an emergency landing because of a rapidly increasing demand for additional power to remain at level flight.
Both crews found that the main and tail rotor blades of their helicopters had glass-clear layers of ice varying in thickness from about one to 10 millimeters on the outboard two thirds of the main rotor blades. No ice was found on the fuselages or the landing gears.
Helicopter pilots cannot be sure that they will be warned of blade icing by ice formations on the fuselage. They also should be aware that ice may accumulate very rapidly on the blades. .
