Repaired crack in Left elevator skin. Cut out a rectangular opening, smooth the edges and rounding the inside corners, then put a piece of primed Alclad (same thknss as elevator skin) on the inside. Secured with 6 dimpled rivets. Will fill the rectanglar opening and glass over the whole thing. Should be relatively invisible...
Set about 1/3 of the top skin to main spar rivets.
Update 07 Jan 2007: Picture below shows repair with Polyfil filler just put on. Circles are the 6 rivets. The approx outline of the rectangular cut out shown hatched.
