Protection from corrosion, which also reduces fatigue strength -- as long as there are no scratches through the anodizing!
Your concern is valid since it agrees with Bickford when he states: "Knowing the strength of the bolt alone is not sufficient, since it's never used alone." "An Introduction to the Design and Behavior of Bolted Joints"
Preload should be based upon calculated joint requirements and not a general...
I had a carburetor ice detector installed in the late 1970's and flew several thousand hours with it and it worked; so the technology has existed for a long time. Tried to sell them without success. An old adage in the aircraft parts industry: "safety doesn't sell"
Economics
Both fuel injection and carburetors have existed in the GA marketplace for as long as I have been in it - early 1970's. More expensive airplanes are generally fuel injected and less expensive airplanes are carbureted. Back in the 1980's we would remove the carburetor from Lycoming...
Try MIL-R-47196 "Rivets, Buck Type, Preparation and Installation Of" Table II
Here is a link to a copy on my web site: http://www.mechanicsupport.com/manuals/mil-r-47196A.pdf

I've been working on a photo glossary of descriptive terms. In repair manuals these descriptive terms are used. Sometimes no one but the author knows what in heck they are talking about:
my examples:
cheek - as in "crankshaft cheek"
land - as in piston land
shank
journal
port
Try this link. It has some good history on wire insulation and wire conductor coatings.

The short answer is yes, 9 years is within the age control limits for the installer/end user.
My previous post was not detailed enough on aerospace hose "Shelf-Life" to properly answer your question.
When MIL-STD-1523 governing age control want obsolete and replaced with AS1933 there was a lot...
Taglia,
Per MIl-DTL-8794 Fuel Immersion test: 72 hours!
I often get asked this question. See my article "Aircraft Hose Age Limitations" at http://www.sacskyranch.com/h_life.htm
"best before date" - Shelf life (acceptance life) is 8 years per AS 1933 revision A. (replaces MIL-STD-1523). Your...
If this is an aerospace application then beam-seal (Dynatube) fittings are replacing 37 degree for new applications because of their light weight. Suggest you contact Parker Stratoflex at (817) 738-6543. You might ask for Mr. Paul Quinn. or www.stratoflex.com

It has been the common recommendation to return a snap style torque wrench to its lowest setting after usage. The often given reason is that the spring, if left compressed, will weaken.
I have always questioned the reason (not the practice). Will the spring weaken (creep) under sustained...
