Required Actions
Accomplish a ground test of the UP/DOWN switches of DUNLOP cyclic stick grip MP/N AC66444 for proper function before each hoist operation. If there is any uncommanded hoist action, remove the DUNLOP cyclic stick grip from service. If DUNLOP cyclic stick grip MP/N AC66444 is installed, before the next hoist operation, install a placard and revise the existing Rotorcraft Flight Manual (RFM) for your helicopter to prohibit the use of the UP/DOWN switches of the DUNLOP cyclic stick grip. Alternatively, remove DUNLOP cyclic stick grip MP/N AC66444, but before re-installing, accomplish the ground test of the UP/DOWN switches and install the placard and revise the existing RFM for your helicopter.
