Here's something interesting, and others can help out on this. tach time and total time probably will NOT agree. Because tachs are setup to read correctly at a given tach RPM reading, if you don't run it at say 2550 for a rpm setting the tach will not read actual hours. It's not noticeable over a few hours of flight, but if you say run it at a higher rpm say, the actual hours in the air will creap up towards the actaul tach time. This is what I learnt from doing this in a 172 I used to own. Try it over a few hundred hours, now imagine several thousand hours
Chris:
If the total of ALL tach times does not equal the total air frame time, something is radically wrong!
The cost of an aircraft is proportionally related to the documentation of the aircraft, the maintenance completed, and the over all appearance of the said aircraft. If the asking price has not been substantially reduced for those short-falls, you should be the one walking away!
