TBO and Overhaul Costs

Is there a website I can go to find out the TBO and overhaul costs of any
given engine? Right now, I am curious bout the GTSIO-520-L on a Cessna
421C.

The TCM GTSIO-520-L as overhauled by any reputable overhauler or as a
factory reman has a 1,600 hour TBO. The later Cessna 421C models (those
with trailing link landing gear) had GTSIO-520-N engines, similiar to the -L
but with a different fuel system. They are a little more expensive to
overhaul for that reason.

The Cessna 421B (tip tank model) has the GTSIO-520-H engine. Early ones had
a 1,400 hour TBO, later ones with better cylinders have a 1,600 hour TBO.
All the Cessna 421's are rated at 375 HP/engine.

Michelle,

Yes, I checked. After they stopped laughing, they gave me an outrageous
quote. My plan is to get my multiengine rating within the next month and
build some multiengine time before my purchase. I know this is not an
easy path.

You should plan on not being able to insure the hull. It is exceedingly
unlikely that you will fly enough hours in a rented twin to get insurance in
a big pressurized one. What was the quote that they gave you and what
were the requirements?

Sami, if you're thinking of upgrading to a twin, take a look at Mike
Busch's article on Annual Inspections in this week's Avweb.
