Narrative:
I was performing the ram air turbine (RAT) deployment test. To perform this test you have to use the pitot test equipment. During installation of the pitot tubes covers/seals; I tried to align all four covers on the pitot tubes the same amount to provide an adequate seal. I was unaware that the pitot tool cover could bottom out and actually cut into the rubber insert in the bottom of the tool. After finishing the job and removing the covers from the pitot tubes I visually inspected the pitot tubes as required by the paperwork and did not notice the small piece of black rubber that had become stuck in the end of the tube; flush with the end. During the removal process of the covers; I was also trying to be diligent and cautious but also careful with my time management because we had an check coming in about 30 minutes.suggestion: the lead was an upgraded lead and not the normal lead for this shift. We had three guys on the job with the same experience level as myself on this job. It could help prevent future incidents like this one from happening by adding a section to the associated paperwork stating to be careful installing covers because the tool could bottom out putting FOD in the end of the pitot tube.
