Continental TBO

[skippydiesel]

In my on going search for a replacement aircraft, I saw an advertisement (outside my price range ) for  a Liberty XL2 powered by a  "Continental IOF 240 B5B - On Condition due to calendar time". I was not aware that certified Ly/Cons had a calendar time (TBO) - comments?

They do. After 10 years in service a GA engine can still pass its annual inspection 'on condition', usually if its within TBO. Not for some categories like charter.

That allows it to be used when it would usually have to be stripped and all seals and perishable bits replaced.

That series is  a later version than the old C-150 motor. Some front oil seals can be replaced without splitting the cases. '"On Condition" often refers to an over TBO permit. You need to KNOW what actually applies if you are going there. Nev

On condition is the norm these days for eng/props for Pvt Ops, was an “about time” ruling some years ago.
