ABSTRACT:
An access lid for a subsurface aircraft servicing pit is provided with a latch located below a surface across which aircraft roll. The fastening mechanism of the improved subsurface chamber is engaged by the force of gravity when the access lid is closed and when a latch operating element is released. The latch operating element is located in a hand grip cavity, accessible from above and defined beneath the top surface of the lid. Actuation of the operating element overcomes the force of gravity and disengages the latch mechanism. Release of the operating element allows the force of gravity to urge the latch mechanism into an engaged position which prevents the access lid from being opened.
