Question 92Gas Turbine - 1st Asst/Chief

The correct answer is B) The engineer's experience. When conducting a borescope inspection, the key factors to be aware of are the inspection areas and ports, the internal reference points, and the limitations of the borescope equipment being used. The engineer's experience is not a direct factor that needs to be considered during the inspection itself, as the focus should be on properly using the borescope tool and interpreting the observed conditions, regardless of the engineer's level of expertise. The other answer choices (A, C, and D) are all important factors that must be taken into account to properly perform and evaluate a borescope inspection, which is why they are not the correct "exception" in this case.
