The bottom and side of the forward fuselage are crumpled when the fuselage hits the ground. The wing hits the ground and bends up just outboard of the strut attch point. The horizontal stabilizer and elevator strike the ground and are bent up. In some cases with enough momentum the entire fuselage can twist and buckle. Most likely some of the more expensive flying you've ever done.
Installation is accomplished through inspection access holes using standard shop tools.
Approximate installation time is 3 to 4 shop hours.
