Narrative:
We received a revised engineering order; B757; from engineering. This engineering order extended the repair time to 200 cycles from 100 cycles. This was previously deferred. Parts of the requirements of revision a were to repair within 100 cycles and accomplish a visual inspection each flight day. When we went to revise the deferral we noticed the every flight day visual inspections had not been accomplished. The deferral was not flagged properly in the computer system. The deferral was corrected and the inspection checked and worked. This deferral was audited daily and the mistake should have been caught. It was originally deferred apr/xa/06.
