Crashing seems to be some sort of badge of honor on these forums, and I always get the impression from reading these threads that crashing a trainer is unavoidable. I think that is a misimpression that gives newbies the wrong idea about LEARNING to fly.

Basically I don't agree that your trainer is doomed to become a pile of toothpicks. Granted I have a blazing six months of solo time on my trainer, but I've only had one major mishap that involved changing a broken engine mount.

If you don't want to crash your trainer...

USE your instructor. Even after you solo you will probably not be overly confident, so ask them to "keep an eye on you". If you feel nervous, ask to go back on the buddy box till your thumbs calm down. Ego is much cheaper than fixing a shattered fuse.

KNOW your limitations. a 15 mph crosswind may be more than you can handle. Don't fly.

PRACTICE LANDINGS - EVERY major trainer crash at our club this year was simply due to the fact that most of the instructors said that any landing was a good landing. My instructor said that until I had landed ON THE RUNWAY 30 times, I shouldn't consider myself "safe". In fact, one of the best aerobatic pilots in our club could only barely land his plane, he finally crashed it into a parked car (narrowly missing my truck BTW). All of the crashes could be attributed to a newbie's luck in getting a plane on the ground running out. I think a really good landing could be turned into a touch and go, i.e., if you have enough control to land where you can spin the engine up and keep flying, you're probably pretty competent.

Certainly nothing can guarantee you won't crash, but I just don't think it is "inevitable" that you will crash your trainer over the course of sane, methodical training.

Of course, once you decide to try and fly inverted at three feet off the deck all bets are off.
