A hatch assembly comprising a frame presenting a frame opening, a hatch for opening and closing the frame opening, a plurality of pivot assemblies. At least two pairs of the pivot assemblies each provide a hatch pivot axis at or adjacent a side of the hatch, an engagement mechanism engagement mechanism configured to releasably engage the pivot assemblies to couple the hatch to the frame, and an actuation mechanism. The engagement mechanism comprises a plurality of pins, each pin movable between an extended position to engage a said pivot assembly and a retracted position to disengage from the pivot assembly. The pins are oriented so that longitudinal axes of the pins in each pair of pins converge enabling the hatch to remain coupled to the frame when the hatch is pivoted between the closed position and an open position.
