Narrative:

While performing a scheduled inspection, work card W57-30-15I, a mechanic asked what I was looking for. The inspection is a detailed visual inspection of the lower wing skin doubler outboard of the nacelle along the leading edge for debonding and missing sealant. I informed the mechanic about debonding and informed him that the debonding usually occurs around the water drains. I looked at the water drain outboard of the collector bay, wing stabilizer YW191 and noticed that it appeared to be debonded. A quick tap test of the area confirmed the debond. Another mechanic then came up to me and asked me to inspect another area of the aircraft. I forgot to write up the discrepancy and did not realize this until feb/thu/02, when I brought it to the attention of my supervisor. A write-up was then generated to have the area re-inspected and repaired. In the company computer maintenance tracking program, there are 2 modifications listed to perform the repair to prevent this type of debonding, but have not yet been accomplished.
