Narrative:
On nov/mon/03, I was the supervisor responsible for air carrier X airlines aircraft X. Aircraft X had experienced a lightning strike as reported by the flight crew. A write-up was left to inspect electrical and instrument system per maintenance manual 05-51-13. As the radio electricians (right&east's) were going through the checks, my manager approached me stating that a mr X had debriefed the crew and that there were no abnormalities noted by the flight crew and that they had a successful ILS approach. I interpreted his statement to indicate that no further action was necessary and I proceeded to sign-off the write-up, (sequence #XXXX). He assisted with the language of the sign-off and prior to entering the sign-off, I asked if this was correct, he indicated yes. After further review, I believe that this may have been incorrect and that the check-outs should have been done. The aircraft has not had any radio or instrument faults since.
