1976 Overhaul, 1100 Hours..Pass???/

I'm looking at at 172 that has 1100 hours since overhaul, holding 73/90
++ on all cylinders...the only thing holding me back, last overhaul was
1976...

Don't pass yet!
Are you sure that's not supposed to read 73 / 80 compressions on all cylinders?
How many hours has it flown in the last year?
In the last 6 months?
Does it have chrome cylinders?
Does the static run-up meet the type certificate minimum rpm?
How many major overhauls and was the last one a quality job?
Is the engine on a low to mid time airframe?
Is the price discounted enough to account for the fact you may need an overhaul soon?

I'm gonna get flamed here, but if it has been flying quite a bit recently, makes good static rpm, has chrome
cylinders and good logbooks, you may be on to a good buy. I'd have a pre-buy inspection done including a borescope
of the cylinders. You should also consider asking the trusted A&P to pull a jug and inspect the camshaft. If
everything checks out okay make an offer based on the above considerations.

ha ha, yeah, I noticed I miskeyed that about .5 seconds after I hit
post, unfortuanltey that was about .75 seconds too late....then I
thought it would look even more stupid to make a correction post!

YOU GOT ME!!!!!!!

Thanks again for the advice! Us younger guys would be lost without some
assistance!

I would verify the accuracy of the log books by checking for entries related
to the 1971 and 1975 substantial damage accident reports as mentioned by
another poster.
I would be very wary of the logs if they are not recorded.

Hey Guys,

I've talked to several seasoned pilots / aircraft owners that say as
long as it's holding good compressions, don't sweat it....

Any opinions?

Thanks,

1100 hours in 30 years. Can you say, "Rust"? I knew you could...

Manufacturer TBO is 2000 hours OR 12 years - its a runout engine, and
the price should reflect it. The cam is the most vulnerable as far as
disuse, yes - all splash lubrication up there. Pull a jug or two and
look, beyond that, if it isn't making metal, burns reasonable amount of
oil, and has decent compressions, I wouldn't sweat it much, either.

OP'er ...grab a copy of AircraftOwner at you local FBO
(www.aircraftowner.com) or Trade-A-Plane and count up how many 30+ year old
Cessna 172 planes are up for sale ...TODAY.

Write down each one on a yellow legal pad. Year - PRICE - hours - top 5
features - location - comments - whatever.

Now, how long did it take to compile your list? Do the same thing next
month - how many new planes between the two lists?

Keep in mind there are even more 172's for sale than just the ones seen in
those two publications.

Thanks for all the advice guys!!!

I just got a call from the current owner...I should have mentioned that
it is going in tomorrow for a complete pre-buy by an AP that is
unfamiliar with the airplane.

I might ask them to pull one or two of the jugs and have a look at the
cam. Is that typically a part of pre-buy???

The airplane is delivered to the AP, my insurance is lined up,
financing is not a problem, I'll post the link and let you guys see
what you think http://tappix.com/728539

Opinions????

Absolutely not. You pull so much as a single nut off a jug of mine, you've
bought the airplane.

Jim,
You are right. I wouldn't want anyone doing that to mine either. What would you recommend on a plane like this
as far as satisfying ourselves that the cam is o.k.? Is a static rpm check and oil filter inspection good enough
(along with the other things mentioned)? An oil analysis history sure would be nice. How about doing one now?
Would you have enough data without an earlier baseline test to make the call?

Unfortunately there's no oil analysis history...that was my first
question....

Let's say this engine DID need at least a TOH.....how much money we
talking about?
