REFLECTOR: Main Tire Tubes

[Jerry Teitsma]

That happened to me as well.  I heard a noise (back when I had hearing!) when taxiing and found one of the bolts had backed out, causing interference.  I also safety tied them and have not had any further problems.

I just replaced my brake liners last week after 5-1/2 years of flying.  I 
remember teaching myself how to safety wire on these same bolts.  Here is a 
picture I took the first time I did it.  It took 2 or 3 tries to get it to 
look this nice.  Well worth the time.

OK, that makes sense.  I forgot about them but safety wire would prevent 
locking up the wheel like you experienced. I have never heard of this 
happening to anyone else.  You have to be wondering, "Why me".  If that had 
happened at touch down it would have been real serious.  I am going to check 
my bolts before next flight.
