Subject: Glasair-List: GL2SFT

As I pulled my plane out of my hanger I heard a loud snapping  noise coming 
from my front nose gear assembly and decided to place a  box wrench on the 
eight trunnion bolts on my fire wall ribs and  discovered they were lose. I 
treat those bolts as though they are  attached to wood and snug them hand 
tight. I found it took about six  flats to snug them up. I completed my Gl2SFT

in 1991 and found  the smaller 3/16" bolts often loosened up. In 1996 the 
day before I  planned on replacing them with larger bolts the nose gear 
assembly  departed my plane while landing on a sandy grass  threshold causing 
much damage. When I repaired the plane I installed  larger 1/4" trunnion bolts

and that appeared to solve the problem. I think  the reason they loosened up 
this time was due to shrinkage of the composite  material over time and not 
the bolts stretching. A few years back I also noticed  the wing brackets 
screws had also loosened. Several years ago I painted  thin red lines on all 
of my elevator bolts to see if they were remaining in  place because getting 
a wrench on those bolts would require removing the  elevators.
