Narrative:

I was working on a dhc-8-300 aircraft from [night] into [morning] performing a secondary flap drive flexible cable lube. Using workcards and (maintenance manual) MM 27-50-10 and MM 27-50-11. During the adjustment of the torque sensor it was found that no caution light was present in the clockwise position. So I was advised by the lead mechanic that we had a bad torque sensor and it needed [to be] changed. I never left the aircraft and the part was brought to me to change. An inspector was present on the wing during the installation process.I filled out the routable tag for the serviceable and unserviceable parts; describing on the routable tag the issue with the part. After installation of the torque sensor the inspector inspected the installation and I was advised to reinstall panels removed. I proceeded to sign-off the work I performed on the workcards as the aircraft was headed out of the hangar and the [maintenance paperwork] package was being closed and aircraft pulled away as I was signing the paperwork. The issue was that I did not fill out an ha-300 for the removal and installation of the torque sensor. It was discovered by the supervisor; during review of the aircraft paperwork; that no write-up had been filled out for the removal and installation of the new torque sensor.the event occurred because we were pressed for time to get the aircraft to the gate. And a lack of communication between myself; the lead; and the inspector. I had assumed that the lead had filled out an write-up when he had told me to change the torque sensor. Maintenance control and the chief inspector were notified.better communication and just slowing down and not rushing the job along would help avoid recurrence of this event.
