Glen Davids Center Spar Damage
Glen found it out the hard way. Too many cracks to have it fixed by a repair shop. So he replaced the whole center piece of the airframe.
Rear spar damage on two places - there is supposed to be a stiffener plate to be riveted to support the rear spar in hard landings.
Main show stopper - a crack in the upper capstrip, just covered up with a piece of aluminim - the "repair" not sufficient.
