In January 2011, I was performing a break in maintenance on a GE 1.5 turbine. I was performing the 100% torque portion of the maintenance. My partner and I started torqueing at the bottom working our way up. This left us with the hub as our final portion of torqueing for the day (fatigue). We would rabbit ear the hub and complete the bottom interior blade bearing bolts and the upper exterior blade bearing bolts we could reach, then rotate to the next blade and do it again until they were all complete. This was very repetitive and required multiple trips out to the hub (complacency). We completed the torqueing without issue packed up our tooling to head down. Before heading down we attempted to clear any errors and found that we had some pitch errors that would not clear (frustration). These errors had us making even more trips out in the hub (rushing/complacency). As I returned to the nacelle from one of these trips to the hub I entered the hatch turned back to disconnect my lanyard and it wasn't there, I had not tied off returning to the nacelle (complacency). An overwhelming sensation had come over me as I realized how big of a mistake I had just made and what could have happened if I had slipped and fell. I took a break and explained what I had just done with my partner at this point our awareness was raised and we safely completed the job. I will never forget this incident as I think of it every time tie off is needed.
