Keep flight controls centered.

After flight operations, the pilots center the cockpit controls during shutdown. If you change the position of these controls during maintenance, the rotor blades and rotor head pitch varying housings are adjusted to a pitched angle position.

When mechanics rotate the angled rotors during maintenance, damage could result. The aft rotor can smash into the anti-collision light. The forward rotor can smash into the forward maintenance platform latches if they are left open.

Save yourself the agony of unnecessary light repair and latch damage or maybe even rotor replacement. Check the clearance of the forward and aft rotors whenever the flight controls are moved from the centered position during maintenance. Center the flight controls again before you exit the aircraft.
