On July 28, 2000, at 1940 eastern standard time, a Cessna 152, N93289, operated by Indianapolis Aviation, was substantially damaged when the airplane bounced during landing and the nose gear collapsed. The 14 CFR Part 91 personal flight was conducting local touch and goes at the Indianapolis Metropolitan Airport (UMP), Fishers, Indiana. The commercial pilot was practicing flying from the right seat of the airplane with a non-pilot rated passenger in the left seat. The pilot and passenger were not injured. Visual meteorological conditions prevailed and no flight plan was filed. The pilot reported he was working on his Certified Flight Instructor (CFI) rating and had taken a non-pilot rated passenger flying to practice flight instruction. The pilot reported he never took his hands off the controls. The pilot reported, "On short final I explained that we needed to 'flare, or pull back on the controls.' [The passenger] began pushing instead. I pulled back and again said, 'No, pull back.' [The passenger] pushed harder so I grabbed the yolk with both hands and yelled, 'Pull back' while trying to regain control. He panicked and shoved the yolk all the way forward, locking his elbows. We hit the runway nose first just right of centerline, crumpling the nose gear and skidded about 200 yards, damaging the prop and underbody."
