Narrative:

This report is for an event concerning a preflight inspection procedure for md-80 type aircraft. Flight involved was an air carrier flight departing at XA00 from iah to ewr. Although it was over 80 degrees F temperature and I had determined that the top of the wing surface had no ice and was dry, the exact procedure for this inspection called out in the gmm 6-14-00 and amm 12- 30-01 was not followed to the letter. An FAA inspector (name unknown) was riding jump seat on this flight. He had asked me if what I did was the correct wing clear ice inspection procedure. Of course, it wasn't. So crossing out previous inspection signoff in the aircraft maintenance logbook, I proceeded to reinspect the upper wing surfaces according to the inspection procedure laid out in the gmm, inspection requires the use of an appropriate size stand positioned at the leading edge of the wing about 6 ft from the fuselage. From up on the stand one should hands on feel as much as possible the front spar of area outlined in the gmm, further, use of a fiberglass 'cue' stick to check the aft portion of defined area which has been outlined with rough/smooth striping. Corrective action would be to follow gmm procedures, period!
