I was just reading Flying magazine's article on the Diamond DA20 XLS (or
whatever they're calling their new, spiffed-up model), and noted that
the TBO on the IO-360 was listed as 2200 hours.

Is that accurate? I thought all Lycosaurs of the 360 vintage had 2000
hour TBOs...

Jay,

Go to Lycoming's home page, click on "Support, Publications, View
Aditional Service Instructions", and look at the last one, SI1009AS. If
you then read "NOTE 11", you see that Lycoming allows a 200 hour TBO
extension on almost any engine, if it has been operated "frequently"
(more than 40 hours per month) since it's been placed in service.
Perhaps Diamond's marketing Dept. is relying on that "little" assumption
to come up with the 2200 hour claim?

Happy Flying!
