Narrative:

On approximately jun/xa/97 I was involved with a #4 tire installation. After aligning the discs on the brake, I had packed the outer bearing and installed the tire onto the brake and torqued it per the job card. I then safetied the nut with its retaining ring and installed the hub cap. On approximately jun/xb/97 my foreman was informed that a mechanic in xyz had found the brake not engaged in the anti-rotation lugs on the wheel. The tire and brake were changed for precautionary measures and the plane returned to service. I was informed of this upon my return on jun/xc/97. To the best of my knowledge the anti-rotation lugs were engaged at the time I had signed for the work completed. I followed the job card step by step, and signed for work completed.
