Yesterday, at Dad's request, I went to to take my Mom, Dad and my daughter flying. We headed to the airport and I went about my preflight routine and Dad went about hooking my tractor to my float dolly, as he always does. It's a good routine, Dad's experienced with tractors, and it gives him something to do while I preflight, besides saving us time. I finished up the preflight and Dad loaded up the plane and headed for the ramp while I closed up the hangar. As I pulled the doors shut I heard a lot of screaming, so I ran for the ramp. When I arrived there I saw, my tractor and Dad, without dolly or plane, parked at the top of the ramp, my daughter and Mom standing beside the ramp, and my plane skimming neatly out into the river. I quickly stripped off all my clothes and swam out to the plane and taxied it to the dock a few hundred feet upstream, I then had to run back through the airport in my gonch (underwear) to get back to the float ramp where it was established that Dad did not lock the hitch closed and did not attach the safety chains. When he made the transition from the flat ground to the sloped ramp the weight shift lifted the hitch off and the plane freely rolled directly down the middle of the 80 foot ramp and launched perfectly. My beaching gear however was now on the bottom of the river. I felt around to the bottom of the wooden ramp (about 5 feet of water) and dove down from there to try to find the dolly in the murky river. No dolly but what I did find is that the river bottom drops very steeply from the ramp. I found a set of parked beaching gear with the keys in it and hangared my plane and went home to do chores, get recovery equipment, and call a diver. No divers wanted to do the job so I welded up a grapple hook in the shop and loaded up a small boat and motor. Dad and I went back to the launch, put the boat in, and fished around with the grapple for maybe 5 minutes until we firmly hooked something in about 25 feet of water and 20 feet off the end of the ramp. We couldn't pull it loose so we decided to tie it to my truck and pull. Lo and behold it was the beaching gear! It pulled out of the river without hanging up on anything, upright, and tongue first, not a mark on it. I hooked it back on to the truck and parked it in the hangar and went home.
Moral of the story. Double check everything, double check everyone who is helping you.
