This Airworthiness Directive becomes effective on 4 August 2005.
Background:	The United States Federal Aviation Administration (FAA) has received reports of injuries to catering personnel and flight attendants who were loading or unloading galley carts on one deck when, due to a disabled or malfunctioning safety interlock door switch, the galley cart lift unexpectedly moved when it was activated from the control panel on the other deck.

This Directive requires replacing or modifying the control panels for the galley cart lift and modifying related electrical cable assemblies, as applicable.  The Directive is issued to ensure that the galley cart lift can only be sent from the deck on which it is in use, which will prevent unexpected movement of the cart lift that could result in possible injury to catering personnel or flight attendants.
