Lee Teicheira and Bill Lawrence, after discovering a crack at the screw hole in the left hand lower front corner of the windscreen, drilled a stop hole at the tip of the crack to prevent additional cracking, roughed up the surface on both sides of the windscreen at the site of the crack, mixed up epoxy, cut two strips of fiberglass cloth, laid up the fiberglass and epoxy on both sides of the windscreen, covered both sides with plastic film, taped the plastic in place and put the windscreen in place on the fuselage so that it could set up in its proper position. Will check on the next work day to assess result.
