EASA 2020-0217-E (Emergency)

Requires installation of a dedicated placard in the cockpit to prohibit in-flight use of the UP/DOWN switches for rescue hoist control, which are installed on Dunlop cyclic stick grips, and to amend the applicable rotorcraft flight manual accordingly. Prompted by an occurrence that was reported of unintended release of the rescue hoist hook during a ground check. The operator was using the UP/DOWN switch when the hoist’s electrically-actuated cable cutter function was activated.
