[quote="gahorn Just because an airplane is being sold by an AP/IA owner is no reason not to perform a full inspection prior to purchase. In fact, it may be even more important.

George I agree with this; but just as stereotypes and generalizations get us into trouble with ethics so does such blanket generalizations offend people. My father was a self-taught journeyman electrician. Born in 1908. When he joined the International Brotherhood of Electrical Workers (IBEW) they gave him back membership rights as he had started working as an electrician before the IBEW existed. My parent’s home was in a constant state of hanging electrical fixtures and open circuit boxes. So I can relate to your previous posting. He knew more about electrical and mechanical things and had a greater intelligence than most men I have ever met. But he did fall short at home.
The 170 A I am repairing. (I would not call it a restoration or rebuild because I allow myself to be expedient) has in my experience the most detailed set of logbooks I have ever seen? As the previous owner only had the aircraft one month he is not responsible in any way for their presentation (although it is possible that I am even wrong in this statement) and as I bought it through e-bay as a salvage project. I have no complaint. The aircraft had obviously had a lack of maintenance and was from what I can glean from the logs and microfiche records previously owned by mechanics and professional pilots. The aircraft as I go through the various systems exhibits what is often discussed in the various topics and threads in this web sight. Pulley bearings being worn out, cables being ready to break from rust and corrosion, cracks in structure etc, etc. I am repairing this stuff as I find it. Had I bought this as a flying aircraft I would suppose that many of theses things would have gone undiscovered in the most diligent form of pre-purchase inspection because a complete disassembly of every component of the aircraft would be to cost prohibitive in the greatest form. And potential buyers are in most cases unwilling to spend the time or expense it takes to do such an inspection. Such is the nature of inspecting flying aircraft. Where in the grass lies the snake that will bite you when the grass is to high to see into any distance.
As a mechanic I often at least know the difference between poisonous and non-poisonous snakes. And so in the maintenance of my own aircraft I have taken at times an expedient route, which is safe because I know it is but I would not recommend to another because it is not acceptable in the main stream considering all issues at hand. Ethically I cannot pass something on to another of this nature.
But as a representative of my own signature certifying that an aircraft conforms to its type certificate in signing off an annual inspection, I am taking responsibility even for those things, which I cannot see, and all of the expedient routes of others that may be hidden in their un-ethical practices.
Consequently some complain about the prices of my annual inspections and how long they take. As a group, mechanics have been accused of holding aircraft hostage because of the issues they discover.
But I do not speak for all or any other mechanics (or those who prefer to be called technicians). I only speak for myself. And I have great respect for anyone who wishes to have a thorough pre-purchase inspection performed. I doubt that it could be accomplished in only what most people seem to think an annual inspection should be comprised of.
A greater price is not a good indication of higher value or proper maintenance. It may be an indicator of expense in maintenance or installed equipment. But a lower purchase price often means the bottom end of the going scale as compared to those aircraft better equipped but not necessarily better maintained. The basic functions of an aircraft are often ignored in this process of determination of value.
Roast me on an open pit for my failure, but let the buyer beware. It is in his or her own best interest. Be prepared to pay the price in any case.
I do sincerely believe that our aircraft are undervalued and this as a result contributes to their being under maintained. I wholly support owner-preformed maintenance by properly supervised and trained people. It brings their awareness up and gives them the ability to survive.
Frankly I am surprised any one would sign off an annual inspection.
And while I am on my soapbox!
Throwing grease at something does not lubricate it.
