Narrative:
The mechanics mistakenly put -300 nose tires on a -700 aircraft! I audited the work package and did not catch the problem by reviewing the paperwork. The problem was discovered by records and the problem was corrected. I signed the lead mechanic line on the parts tag. That was the extent of my involvement. After going through a lot of work packages; I probably tend to become complacent.
