i Determine the color of the switch unit mounting flange. If the mounting flange color is any color other than red, determine the purchase date. If the purchase date of the switch unit is between April 19 and July 26, 2004, or cannot be determined, do an operational test.
ii If the switch unit fails the operational test, before further flight, remove the switch unit from service.
3 As of the effective date of this AD, do not install a switch unit identified in paragraph c1 of this AD on any helicopter.
