Narrative:
On the evening of jul/tue/06; I was asked to assist in the evaluate and possible repair of a lightning strike damage on aircraft X. The damage was on the #1 engine outboard translating sleeve; aft edge 7 O'clock position to 9 O'clock position. After examining the area and consulting the srm; it was necessary to contact engineering for clarification on whether or not this was an edge-band area. After a few conference calls with myself; my supervisor and an engineer it was determined the damage was in an edge-band area. This would allow it to be classified as allowable damage. I began to perform the required sealing of the damage on aircraft X. I was having a difficult time getting the area dry enough for the speed tape to adhere correctly. I took about 2 hours using vacuum; heat and nitrogen. By the time this was completed it was late; approximately XA00 or XA30 am. I had been signing off the paperwork for my aircraft; when I was handed the non routine for aircraft damage. At the time I did not realize that the non routine incorrectly stated the damage as being on #2 engine instead of #1 engine. I believe I perceived my lead would have all the facts correct on the non routine. I feel this situation may have been caused by fatigue and stress; on the parts of myself and this discrepancy was brought to my attention on the morning of sep/thu/06; by a 'B/C' check inspector. A non routine card was entered into maintenance history to correct this discrepancy.
