Claim:
A method for mounting a maintenance step on a fuselage of a helicopter comprising: a casing, integrated into a lateral shell of the fuselage of the helicopter with access from outside; and a step being pivotably mounted in the casing; the casing being provided with an essentially rectangular frame and a rearward extension with lateral sides, the rearward extension with lateral sides being integrated into the lateral shell of the fuselage of the helicopter; the lateral sides have coaxial borings; the step being provided with corresponding coaxial borings in lateral flanges; two pins being provided for insertion through the corresponding coaxial borings into the coaxial borings in the lateral sides of the rearward extension for pivotable mounting of the step in the casing; and a retaining profile being provided for securing the inserted pins in their position; wherein said method comprises the following steps: inserting the rearward extension of the essentially rectangular casing of the maintenance step into the prepared fuselage of the helicopter; riveting the essentially rectangular frame of the casing flat against the lateral shell of the prepared fuselage of the helicopter; inserting pins from within a mid box through the corresponding coaxial borings into the coaxial borings in the lateral sides of the rearward extension; clipping the retaining profile into the grooves at the inwardly pointing ends of the inserted pins to fix the pins in their position; and screwing the step cover onto the step to fix the retaining profile relative to the grooves in its clipped position.
