TBO guidlines

Post by 3wannabies »

Hi Everyone, I am new to the airplane buying world. Ironic since I have been a flight attendant for over 30 years!!
I am in the process of buying a 172 for my son's pilot training for him to build hours faster.
I have a 1965 172 with 2600 hrs on the engine and the current owner says that as long as the engine run well it's fine. I was under the impression that TBO on a 172 was 2000 hrs. Is that a red flag?? Or is that only for flight school and commercial operation. Any help would be appreciated. Thanks.

'Right place for the question....

Generally, I agree with what you've been told, if it's running well, keep running it. That said, running well is more than it starts and you can fly it. good compressions, low oil consumption, good oil pressure, no metal in the oil, no leaks, and spark plugs and accessories maintained as they should be.

I had an O-200 I ran to 3600 hours, no problem. Even at overhaul, It was in great shape. Run it regularly, and maintain it. Overhaul and repair as required by condition.

Commercial registered planes are different...

Commercial aircraft can operate past TBO on a per-operator case by case basis, with additional inspection actions, by agreement with Transport Canada.

Yes you can run it privately, but also accept that it might need an overhaul any time. Which is also the case for a low time engine, but generally you could say that chances to be needing an overhaul will increase as the engine time increases. It definitely lowers the value of the plane though. The owner might claim it will run as good as a 1000 hour engine -and he might be right-, but it's definitely not worth as much.

Remember, the questions you are asking yourself now, will also be the questions future buyers will be asking themselves if you end up selling the plane again.

As an AvCanada discussion grows longer:
-the probability of 'entitlement' being mentioned, approaches 1
-one will be accused of using bad airmanship

In terms of cash value, the engine is worth core value only, any extra flying hours are a bonus for the purchaser. Don’t let the vendor tell you otherwise.

Ask if they have been having oil analysis done on every oil change and then ask to see it as well. A high time engine with oil analysis done and good compression is preferable to me to a low time engine that flies twice a year and never had any trend monitoring. That being said any used aircraft could have an engine failure the day after you bring it home and it would be wise to have a budget plan that could accommodate the overhaul cost.
