Airworthiness Directives; Boeing Model 747-100, 747-100B, 747-200B, 747-300, 747-400, 747-400D, 747SR, and 747SP Series Airplanes

摘要

The FAA proposes to adopt a new airworthiness directive (AD) for certain Boeing Model 747-100, 747-100B, 747-200B, 747-300, 747-400, 747-400D, 747SR, and 747SP series airplanes. This proposed AD would require replacing or modifying the control panels for the galley cart lift and modifying related electrical cable assemblies, as applicable. This proposed AD is prompted by reports of injuries to catering personnel and flight attendants who were loading or unloading galley carts on one deck when the galley cart lift unexpectedly moved when it was activated from the other deck. We are proposing this AD to ensure that the galley cart lift can be sent only 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.
