A method for detaching or installing a rotor blade from or to a hub of a wind turbine includes positioning the rotor blade toward a ground location between a three o'clock position and a nine o'clock position. The method also includes mounting a mechanical arm to an uptower location of the wind turbine. Further, the mechanical arm includes a torqueing tool at a distal end thereof. Thus, the method also includes removing or installing, via the torqueing tool, each of the plurality of hub fasteners so as to detach or attach the rotor blade from or to the hub.

A borescope is received within a housing. The borescope includes a flexible end portion carrying the video head and a housing includes a flexible end portion comprised of ball-socket segments and a tip for following the movement of the flexible end portion of the borescope. Cooling air is provided in an annular passage between the borescope and housing for flow about the borescope to maintain the video head temperature below its temperature limitation. Two cables maintain the ball-socket segments and tip in contact with a transition piece and with one another to enable the flexible borescope end portion to follow the movement of the directionally controlled video head.
