Narrative:
Brake check task card #XXXX was mistakenly marked 'north/a' due to misinterp of the card by myself. The functional check of the secondary stabilizer trim brake was not performed due to this mistake. This information was brought to my attention by a co-worker on nov/tue/02. I immediately notified maintenance control. Supplemental information from acn 565212: I north/a'ed the inspection block and co-signed it. I did not question the mechanic on what the dash number was.
