Instead of second guessing a recent accident " Which I am guilty of myself " I figured we could post things silly things that darn near killed us.
1. Two years ago after an extensive rebuild and super annual, the plane ran fine for the first three or four hours of flight.
...Suddenly I started to get all sorts of radio static noise when i was out in the middle of no-where with a student.
....Then the engine started to fire oddly with power loss.
....The Cause,,,,,, The long screws that hold the magneto cap assembly had not been property tightened after the timing check. After a .....few hours the screws fell out and the magneto cap started to disassemble itself. The radio noise was when it first opened up and ....let the arc and spark noise leak out, via radio waves.
Now I grab my mags and try to shake them before every flight.
2. Many moons ago I picked up a friend at Birchwood in my old J5 / PA-12 hybrid. I just landed, he got in with all his hunting stuff and I started a taxi to the runway. There was lots of traffic and during taxi I had the stick full back.
When I saw a hole in the landing traffic I pulled out and fire-walled the old 0-290D2 in hopes of a quick take-off. BUT... the stick would not go forward more than a couple inches.
It turned out that my hunting buddy had never been inside a Cub type plane before. So while I was taxiing around Birchwood he shoved a small day-pack between the rear stick ( I was full back) and the back-side of the front seat. So he was busy eating jerky from the pack while I was busy trying the compress it with the stick. The aborted take-off was bad enough and made worse by all sorts of landing aircraft who were on final...
Now I do a better passenger brief and box the controls all the time while taxiing..... No matter that I have already been airborne that day.
3. After pulling the floats off one dark winter evening... I was taxiing the plane out of the Homer Air hangar and over to my parking area. I had also just changed the spark plugs and the PA-11 seemed to be running better.
......I stopped to do a run up and then thought that maybe I should make a take-off and a run around the pattern.
The wing covers were still on the wings! And I only noticed after I was rolling onto the deserted active runway.
I do not know why i had such a major brain fart.... That plane did not even have any lights, so what the heck was I thinking for those 20 seconds.
