A pressure equalization vent for use in an aircraft assembly is provided. The pressure equalization vent includes an opening having a first end and a second end opposite the first end, and a first side and a second side opposite the first side. The vent further includes a plurality of louvers positioned within the opening. Each louver is positioned a predetermined distance from an adjacent louver to form a gap therebetween. Each louver includes an airfoil-shaped cross-section configured to increase airflow efficiency across the vent.

A fairing panel retainer can include a retainer strip that is configured to conform to the contour of a vehicle body. The retainer strip includes alternating body attachment segments and raised panel attachment segments in a generally corrugated configuration. In addition, each of the body attachment segments includes a body fastener interface configured to accept a permanent fixed fastener to attach the fairing panel retainer to the vehicle body. Each of the panel attachment segments can include a panel fastener interface, for example, a bore through the panel attachment segment and a fastener plate slidably attached to a lower surface of the panel attachment segment. The body fastener interfaces and the panel fastener interfaces can be closely aligned along a longitudinal line or arc of the retainer strip. The fairing panel retainer can also include a transition surface to provide a smooth transition from the vehicle body surface to a fairing panel.
