I have California teaching credentials in four subject areas including Aircraft and Aerospace Technology. I started teaching at Fort Eustis, Virginia on contract managing a course on three types of Sikorsky helicopters. I had platform instruction experience on two assignments with the Air Force and NASA. I have also taught Aerospace Technology in the Los Angeles and Santa Barbara school systems.
Normally, when I am on assignment as a consultant I locate the nearest A&P school and offer my services teaching helicopter aero dynamics. The last time I was able to do this was at Frederick Community College in Frederick, MD and at Ivy Tech State College in Terre Haute, IN
I also want to use this space to add some additional information to my post in response to your first post in this thread.
Another point that effects the reliability of components is a condition known as batch sensitivity. This means that if more than one item of the same design is exposed to the same manufacturing processes at the same time. If one is found defective in service another item that was processed at the same time could have the same defect. This is especialy true for springs or any other item that requires heat treating and vacuum degassing. Another thing effecting springs is the wire draw process which can introduce inclusions which can weaken the spring. This inclusion can be in only one spring or it could be in all springs that were made from that same wire draw. Springs that are used in critical functions such as those used in servo mechanisms should all have 100% QC. Most companies don't do this as it is very expensive.
Another problem resulting in failure is maintenance error or mishandling either during manufacture or during component maintenance.
Sorry for going on so long.
