Narrative:
On feb/fri/03, I was notified that a panel on the horizontal stub of aircraft was missing (reported on feb/fri/03). I was also told that my employee number was recorded on documents for installation of this panel on a quarter D check in november of 2002. To my recollection, this panel was installed properly per the maintenance manual, and brought back by quality control. On many occasions, 2 or more mechanics work together on closing up the aircraft. I remember working with other mechanics on this close up, and we signed off paperwork together. Panels were checked for security, and all were secure at date of signoff.
