Abstract: Maintenance steps on helicopters (10) comprising a casing (1), integrated into a lateral shell of a fuselage of a helicopter (11) for access from outside and a step (2) being pivotably mounted in the casing (1). The invention relates as well to methods for mounting and dismounting of such maintenance steps.

Abstract: The invention relates to a door lock comprising a door catch system for double door-type helicopter doors that can, when being closed, additionally be displaced perpendicularly to the plane of the door opening into the closed position (flush fitting). Said door lock comprises a catch element (30) associated with the latch element (31) and actively linked therewith, said catch element maintaining the door ‘caught’ directly in front of its locked position when the door is manually closed until the door is translated to its final closed position via the latch element (31).

Abstract: A locking device having a door catch system for helicopter doors, which are embodied as sliding doors, which are to be additionally moved (flush-fitted) into the closed position at right angles to the plane of the door opening in response to their closing movement, consisting of a catch (15a), which is associated with the latch (13) and which is in active connected therewith, by which catch (15a) the sliding door is “caught” directly in front of its locked position in response to a manual closing process until the sliding door has been transferred into its final closed position via the latch (13).
