Narrative:
I work for air carrier X and on several occasions in the last week I have been on duty for 50-hours; slept for 7-hours; then was on duty for another 30-hours. In that time I did many aircraft turns and tried to troubleshoot several problems with aircraft? My immediate supervisor has no problem working crews for 24-hours at a time; with little rest in between duty days. This is getting very dangerous; as people are starting to make mistakes due to the fatigue caused by this unrelenting schedule.
