Continental "1800 hours or 12 years" rebuild

[sbmackie]

Having never owned an airplane with a continental engine, I want to make sure I understand. The TBO for any commercial operation (including flight instruction for hire) is 1800 hour or 12 years since previous rebuild, whichever occurs first. True or false?

Thanks

False. As long as you are operating under Part 91, TBOs are advisory.

Yes, but he said Commercial operation including flight instruction, so he is correct.
Only exception to that that I’m aware of is part 137,Ag.you can fly Ag and make a living doing so and in the US anyway not follow TBO’s.

And on edit, I believe its overhaul. may seems silly, but the FAA can get wrapped around the axle by what name you call it.

I disagree. You can legally give flight instruction in an aircraft with an engine that is beyond TBO. The FAA does not consider flight instruction (or rental) a commercial use of the aircraft; it is still being operated under Part 91. Now, if you want to carry passengers for hire, it's a different story, but then you are no longer operating under part 91. (I have never seen a 120/140 operating under Part 135...)

That said, if the aircraft is used for instruction, it must have a current 100 hour inspection, something that is not generally required for operation under part 91.

I'll second that, TBO per Cont. is only a recommendation in the part91 world.

However the original post clearly stated Commercial operation. Part 91 is clearly NOT Commercial.
Your explanation of why TBO does not have to be followed in your instances are predicated on the FAA determining that flight instruction and rental is not a Commercial operation.
Not that I expect to see a 140 in a part 135 operation, but in AK there are several cubs in part 135 ops, and that is a Commercial operation as an example.
Any aircraft used for Commercial operations has to follow TBO’s.,with the exception of part 137, as a Commercial pilots Certificate is required to fly Ag for hire, I assume it’s considered a Commercial operation. You can spray your own crops with a private pilots certificate, but you have to have a Commercial one to charge money.
There may be other exceptions except for 137, I don’t know, I never thought about rental aircraft for instance
Maybe not true, but I have always used the rule of if you charge or make money for flying, it requires a Commercial ticket, and since it requires a Commercial ticket, it’s a Commercial operation.

I take your point. It just happens the the question originally posed has 2 different answers depending if you are talking about only for the purpose of flight instruction versus other commercial applications that you point out. If the OP went by your rule, it certainly wouldn't hurt but if it is really about flight instruction, that would be a rather costly rule assuming the engine is in good working condition. It all boils down to what specific uses the OP intends.

[6643]

BTW, the fact that it is a Continental engine is irrelevant. The same rules apply (or don't apply) for Lycoming (or Franklin, or Pratt, or RR, or...) engines, just the numbers are different. Note also, if there is a life limited part, or an AD, things are different. However, the original question didn't delve into any of those areas.

Years ago I owned a Beach Musketeer that was used for instrument training and rentals. I put 2400 hours on the Lycoming O360 in a little over 3 years. TBO (IIRC) was 2000 hours.

The question is true/false. Flight instruction is not considered a commercial use of the aircraft, so the entire statement is false.

Maybe we should wait for clarification from the original poster before we go down any rat holes.
