Default Have you ever caught a problem during preflight?

So I was doing preflight this morning before going up for some spin training (non RV but forgive me) and I got to thinking...I wonder how often people catch problems during preflight. I'm just wondering what the hit rate is...not really trying to push any kind of agenda, just curious.

Just to be clear, I'm only talking about during the walk-around portion...not run up and control checks and stuff.

Not an RV, but my preflight on the skyhogs I fly always includes a gentle up-down wiggle of the horizontal stabilizer near the root, on each side of the aircraft. I noticed some "squishiness" when squeezing the rib nearest the fuselage to give it a wiggle, which prompted further investigation. One of the bottom rib-to-skin rivets was smoking and could turn in its hole, so I grounded the aircraft.

Good thing, too, because upon disassembly the A&P found the horizontal stabilizer rib was completely cracked through. To date still not sure how it happened or how long it had been flying that way. Oh, and note the lack of primer on a certified aircraft that's over 30 years old

Default Yes!

Over the years I've found low tires, bird nests, bugs/spider webs in vents/pitots, loose gas caps and (most embarassing) missing access covers following (my) maintenance. Just like the flying part; hundreds of boring inspections punctuated by terrifying discoveries.

Default INSPECTION

I turned up a missing cotter pin once in a very important place. I was told to look for birds nests and it took over thirty years of flying to finally find one but it made all those pre-flights worth while. Collapsed nose strut bottom out but that was an easy one. I test the brakes too before even looking at the check list once inside and have had one of the pedals go to the floor on occasion.

I force myself to walk around just to make sure I disconnected my tow bar.

Default Check the oil

Our flying club in college washed the planes every Sat morning. Someone would take it around the pattern to partially dry them and then towel completely. Only problem was the 150 was in for an oil change and in haste to build a few minutes of free flight time a student pilot didn't check the oil or the oil pressure gauge. He made pattern alt downwind without any oil then 'landed' (sank) in a lake and survived but good bye Cessna 150.
