Claim:
1. A method for inspection of a gas turbine comprising: activating an inspection apparatus, the inspection apparatus comprising one or more inspection tools arranged on a track, each inspection tool comprising an extendible shaft having a proximal end that is attached to the track and a distal end carrying a sensor; and operating the inspection apparatus to move the one or more inspection tools to an inspection position, wherein the respective shaft of the one or more inspection tools is extended outward from a retracted position to guide the sensor into a respective inspection port of the gas turbine, wherein the track comprises a rail track that is positioned parallel with respect to a longitudinal axis of a turbine section of the gas turbine, wherein the inspection tool arranged on the rail track is controlled by the control system for insertion into the inspection port of the turbine section of the gas turbine with respect to an radial direction of the turbine section, wherein the track comprises a ring track that is positioned coaxially with respect to a combustion section of the gas turbine, and wherein the inspection tool arranged on the ring track is controlled by the control system for accessing into the inspection port of the combustion section of the gas turbine with respect to an radial direction of the combustion section.
