1. A wind turbine blade, comprising:
a profiled contour comprising a pressure side and a suction side, and a leading edge and a trailing edge with a chord having a chord length extending therebetween, the wind turbine blade extending in a spanwise direction between a root end and a tip end;
an aerodynamic shell having an outer surface forming at least part of an exterior surface of the wind turbine blade, and an inner surface,
an access window extending through the aerodynamic shell, wherein the aerodynamic shell comprises a recessed portion at the inner surface of the aerodynamic shell adjacent to the access window,
a panel arranged within the recessed portion at the inner surface of the aerodynamic shell for closing the access window, and
one or more sealing members arranged between the panel and the recessed portion at the inner surface of the aerodynamic shell.
