Narrative:

I was temporarily assigned to the avionics department for vacation coverage. I am a CAT III certified mechanic and am familiar with the aircraft. Several nights I worked alone and performed many tasks, among which was CAT III recertification. I may have used improper verbiage for CAT status signoffs on several aircraft. Upon the return of the regular avionics technicians, I became aware of my mistake and have familiarized myself with the company maintenance policy and procedures manual.
