My partner and I were assigned to do an ETOPS inspection on Aircraft X. While doing our walk around; we found evidence of a bird strike on the First Officer's side; aft of the radome; and before the pitot tubes. At that time we told our Crew Chief; and Supervisor that we had the item; and our crew chief pulled up the bird strike inspection paperwork. While accomplishing the card; Step 5; tells us to deactivate the GCS antenna; or to [skip] this if no indication of bird strike on the crown. The issue with this is we're told in step 2 to do an inspection from the ground (in which case; you can't see the crown of the airplane). The next item we had; was step 7 (in the notes) that 'If GCS is installed; inspect the GCS Antenna Radome. When we pulled that AMM (Aircraft Maintenance Manual) reference; this was a detailed inspection; of which the antenna needed to be removed to properly inspect it. We then contacted engineering; for relief from these items; as we could not accomplish them as they were written. An Engineering Authorization was issued. We thought nothing of this; until we were brought in today to do the 5 question part of the Investigation Form; by Manager. We found this odd; as he was present at the time this issue was developing; and our understanding; was that anyone involved in the issue; and wouldn't be involved in the Investigation Form process.
