TBO & time

[tinman]

The O-300 has a 1800 TBO and 12 years. If I have a plane that is under the 1800hr but is over the 12 year, can it be rented out and also be used for instruction? Thanks.

Yes, TBO is a manufacturers recommendation, and though they are required to publish one, the owner is not required by regulation to comply with it. As long as the engine can pass an inspection (compression test, ect.) it is legal to fly.

As far as renting an a/c with a "timed out" engine, in my exprerience I have found that there will be a certain stigmatism about renting one in a segment of the pilot population. I was renting a twin once with one very high time engine, and would often hear from fellow instructors who knew the plane "you're flying that POS, the right engine has xxx hours on it" (the time ranged from "at least 2500" to "over 3000"). In reality it had something like 2200-2300. Engine never quit.

I've flown aircraft with engines with over 3000+ hours. If they are flown on a daily basis and well maintained a simple engine like a O-300 or O-360 can last well beyond the TBO. The key is good mx and best to do oil analysis atleast every other oil change after you've reached TBO.

So as long as its part 91(and passes all inspections),it could be flown over the times listed above, right?

 

[DrewBlows]

Yes.

Unless the manufacturer has assigned it as a mandatory overhaul time. TBO can still be limiting.

Don't forget to consult your insurance company.

How do I find this out? Thanks

P.S. Where have you been hiding Avbug?

 

[avbug]

You'll find it in the maintenance publications put out by the manufacturer. In this case, with a 0-300, you're only looking at TBO as a mandatory limitation if you're operating under Part 135.

I've been firefighting (still am).
