摘要： A swivel access structure for an engine nacelle, including a door plate, a first fastener, second fasteners, a door frame, and one or more flame shields. The door plate is selectively rotatable about the first fastener, and the second fasteners selectively release the door plate to allow its rotation about the first fastener from a closed configuration to an open configuration. The door plate is rotatably attached to the door frame via the first fastener. The door frame has a frame opening covered by the door plate when the door plate is in the closed configuration and exposed when the door plate is in the open configuration. The one or more flame shields cover an inner side of the door plate and/or an inner side of the door frame. The swivel access structure provides access within the nacelle without spring arrangements that are more susceptible to fail fire testing.
