Multiple Cessna 172RGs made me a better pilot
I turned toward my side and saw that the the left main was hanging but not locked in the forward position. Uh Oh! I immediate called the Tower and explained my situation and they sent us out over toward Lake Winnebago to manually pump the gear down. A C-172RG gear should pump down and lock in 35 strokes (just like in the movies). About pump 100, I knew this was not going to work. It was a hydraulic system failure.
