Just like the Mobil fuel disaster which allowed us to go into areas where we normally could not go the amount of things that were found was quite amassing.
Sids has come about for a number of reasons. Its is what maintenance orgs have found and reported back to the manufacturer, what the manufacturer has found themselves and the fact that the manufacturer did not expect that these aircraft would still be in service now.
In the mid 70s early 80s GA cessnas and other manufactures was booming here in Aust. Aircraft were relatively cheap and disposable.
Much like Beechcraft which had a buy back of the starshio so they could remove its type cert and there fore not have to support it. Some people didn't not return it to beech so they couldn't do it.
Cessnas answer was SIDS. This was to remove as many aircraft as they could by making it so hard and expensive to do, that you would walk away.
Problem is in many cases there are no alternative aircraft available and what are are extremely expensive and out of reach for most.
So some SIDS were you have to remove a rivet that is in a totally incesable position clearly chosen for that very reason to make it as hard as possible to do. Its clearly seen for what it is, to remove the aircraft from service, So what happens we do the inspection find nothing loose money on the service because the owner jumps up and down at the cost.
One saving grace is the now availability of relatively low cost of boroscopes that allow you to get into some of the tighter spots with out the need to disassemble de rivet a complete assy.
Now someone complained about the cost of doing an inspection and that its 1/10 of his hers wage, im sorry how is that my or anyone else's problem if they cannot afford the cost of ownership. I don't see many LAMES in GA with gold teeth. In fact that the LAME has subsidised the GA industry for ever with little or no reward for what the he or her has to achieve to get to the position of holing a Lic. Not to mention the legal holding which goes along with that.
Maintenance in Aust has always been cheap for what has been provided. This can be seen by the way that the average age of Lames is increasing and why the fact not many people are coming and when they do leave the industry. The fact that maintenance orgs are closing down and no new ones are opening up.
SIds is just one more thing if you own a Cessna you have to do to managing your aircraft in a serviceable condition.
ANd leadie isn't it time that you removed yourself from the chair and go to the crew rest
