If the Boys in the know approved then I guess they are OK.But keep in
mind always that harder is not necessarily better.Sometimes these bolts
are ment to bend before they break.If the bolt is stonger but can't bend
then it may reach a stress point one day where it will break and not
bend and you may be in a world of trouble.A bent bolt that is seen is
better than a bolt that is close to letting go and can't be seen by the
naked eye.At least that's what the guru's at my field say anyway.I
didn't make up all this stuff.Everything I know about bolts I got from
the boys at the field.I've tried to cut corners but these guys are bent
on keeping me alive.

Remember on additional thing. I believe Grade 8 bolts have cut threads, e.g. stress
risers, while AN bolts have rolled threads.

| Subject: | WOW, Jeppesen FlightStar VFR software |
I received my Jeppesen FlightStar software last night and have been tinkering with
it this morning.
It is a lot more sophisticated than I'll ever need for flying LSA, but the ability
of this software to route around complicated airspace in an airplane not having
radios or a transponder certainly helps for planning a long cross-country
flight in an antique airplane.
This would have been great for Chuck Gantzer's flight last year around the country,
and if anybody is in need of something that has a lot of flexibilty for flying
in the LSA environment, this looks like a really good tool, especially since
it can be coupled with a GPS on your laptop through a USB port. I haven't
tried using this with my Microsoft GPS yet but will in a week or so. Now, if
I can just find a smaller laptop to haul in an Aircamper, I'll be in good shape.
I paid $129.00 for this at MYPILOTSTORE.COM (I got free shipping) and so far, I'm
very pleased with the purchase. They shipped it fast.
In order to update the software, you'll have to pay for an update occasionally.
I think this can be done on a per-need basis or monthly or annually through Jeppesen.
The phone help at Jeppesen was very good when I contacted them this morning
for assistance.

There is one important thing. The grade 8 bolts are used worldwide for high strenth
aplication, including homebuilts,
Someplaces (here for example) for years aircraft and parts imports were baned,
very expensive and needed lots of paperwork, so we used in our projects grade
8 bolts one size bigger than the AN called for in the plans (where space possible).
Never had a problem and some are still flying...
In lots of my projects, I made my own bolts an hardened them (yes, I have the
equipment), I used to make and sell grade 8 bolts for truck leaf springs as
a student,
Here is a page in the Fly5k group about my Flea, in page 2 the two elevator
control eye bolts were made by me (grade 8).
http://www.fly5k.org/MEM/GaryPouchel/GaryGower1.htm
I always wanted to know this:
Where did the Pioneer Homebuilders including Mr Pietenpol bought their AN bolts?
Since what year where the AN bolts available for homebuilders? After that time
what bolts were used?
You know what? Years ago I made Casein glue, just to learn how to do it,
Well I made a stool and a table for my shop and they are still bonded, this was
about 20 years ago... But yes, you are right, I am to chicken to test that
glue in a plane, T-88 is good enough :-) :-)

I may be wrong but I think the first AN bolts came from the Navy ship
yards.I believe they had certain standards they had to adhere to and
that's where it all started.As to the date;I have no idea,maybe someone
else knows the answer to that one.

Points about threads, bending and brittleness made in this discussion are all very
valid. I should have made one additional point earlier. All of these Grade
8 bolts are replaced with each annual condition inspection. I have not seen
any wear but changed anyway.
I do appreciate the exchange of ideas. It makes us all safer in the end.
