Narrative:
I was working my normal day shift of jul/fri/04. At approximately XA30 I was given a gate call slip informing me aircraft was returning. The flight crew reported a nose gear unsafe indication. The message also specified the aircraft may be overweight upon landing. We proceeded to gate and awaited the arrival of flight. After arrival, we debriefed the flight crew and they explained the situation. I continued to ask questions to both crew members about the discrepancy to aid in troubleshooting. During this time the captain was finalizing his log entry when he stated he landed overweight. I responded by asking if he noticed anything different about the landing, at which point he indicated the landing was uneventful and normal. We decided the best method to troubleshoot would mean retracting the nose gear. Therefore, we needed a forward body jack. At this time our supervisor arrived at the gate. The 3 of us coordination to get the jack and related hardware. In preparation to retract the nose gear, I pinned all gear. During the process of pinning the gear, I performed the overweight landing inspection. No defects were found. We cycled the nose gear multiple times and confirmed the fix. We realized the logbook was not on location. The logbook would have to be retrieved from the line maintenance lead office. I immediately signed off the right&right of S-845 per maintenance manual. Though it was completed several hours earlier, I failed to make an entry stating accomplishment of the overweight landing inspection.
