Narrative:
I got a call from maintenance controller about what information was on the hydrostatic test records. I opened a file to get information and read off what goes on test record. I closed file and put it away, I woke up monday morning at XA00 with a bad feeling. I got to work and got the file out and found that I had not calibrated the stand to 1% as required. I was very tired, and under a lot of stress. My 26 yr old son had just had his second cancer surgery and my sleep pattern was not good. He was in the hospital, released, and then readmitted. All the cylinders which were tested were recalled and retested.
