FIELD: aviation.

SUBSTANCE: invention relates to aircraft engineering, in particular to structures of devices and methods for enabling use of temporary inspection door, intended for use during search and rescue operations, in fuselage door opening. Device can be made with central support post made with possibility of attachment to aircraft fuselage interior structure for arrangement of central support post in vertical position in internal space of aircraft fuselage. Device comprises alternative doors, for example sight doors, made with dimensions and configuration, providing for its rapid installation in door opening in aircraft fuselage, when aircraft main door is in its open and retracted state. Both doors are connected to central support post with the possibility of disconnection and with possibility of their displacement for placement in such position, that to close aperture in aircraft fuselage, at their disconnection from central support post.
