Locking apparatus for a service access in an external structure of an aircraft, service access, aircraft and method for producing a locking apparatus for a service access in an external structure of an aircraft

A locking apparatus for a service access in an external structure of an aircraft, the locking apparatus comprising:

• a base structure for fixed attachment in an opening of a service access in an external structure, wherein the base structure has a through opening, which extends along a longitudinal axis;
• a covering device, which is supported to be movable along the longitudinal axis in the through opening and relative to the base structure, wherein the covering device is preloaded by a spring device and is held in a closure position by a stop in interaction with the spring device;
• and
• an actuating shaft, which extends along the longitudinal axis, has a handling end region for rotational handling by a tool, and a transmission end region for transmitting a torque to a lever unit coupled to the transmission end region, wherein the handling end region is surrounded by the covering device, and wherein the handling end region and the covering device are arranged with their surfaces flush in respect of a respective outer side.
