I believe the strongest part of any Cessna Single is the newer style Landing gear.
At the flight school I flew and worked at, In Jan 09 they had record low temperatures. We have a big hangar with a 60-70 x 20 foot bi-fold door on it. Well one of the cables snapped which caused the others to fail and the door dropped down onto the 172R they were pushing out by hand. It landed right at the rear window frame just behind a student who was pushing the plane on the strut. The door ended up resting on the plane with the gear slightly compressed. When they lifted the door off of it, the plane sprung right back up.
