Collective pitch reduction must be immediate but not a panic reduction. The pilot who is ham-fisted and slams the collec-tive down runs the risk of blade-to-fuselage contact or a rollover in the opposite direction, either of which can ruin a pilot’s whole day.
Prevention of dynamic rollover is simple. Control the roll rate. Prevent the roll rates from becoming excessive by judicious use of collective. Control the roll rate. And, if control seems marginal, lower the collective.

Insidious Rotor Ice

Pilots should be particularly aware of blade icing. With barely any warning, ice can form quickly on the rotor with no sign of it on the fuselage.

Aage Roed
During the analysis of a helicopter accident, an investigative team speculated that rotor ice, which accumulated while the helicopter was hovering immediately below a cloud base, may have been a contributing factor. In the post-accident report it was also stated that ice may have accumulated on the rotor blades, although no ice could be detected on the wind screens or the fuselage structure.
In response to the analysis, operators have noted that ice will always show on the wind screens and fuselage structure at the same time that it accumulates on the rotor.
