HI THERE
=0A=
=0A= There are TWO numbers suggested for TBO.
=0A=
=0A= one =3B we are all familiar with=2C which is the number of hours= of operation
=0A=
=0A= and
=0A=
=0A= the other we tend to ignore=2C which is the number of years in servi= ce.
=0A=  =3B  =3B =3B i believe that it is twelve years or some similar= number of years.
=0A=
=0A= i personally have ignored this "timing out of the engine"
=0A=  =3B  =3B  =3B somewhat to my own peril.
=0A=
=0A= over the course of my ownership of Large Continental =3B Engines=2C
= =0A=  =3B =3B =3B =3B =3B i have had three engine that neede= d overhaul due to ravages of time=2C as opposed to wearing out.
=0A=
=0A= we all know about the "soft" cylinders" on Continental Engines=3B
=0A=  =3B =3B =3B =3B =3B =3B =3B =3B =3B&nb= sp=3B =3B =3B =3B =3B =3B =3B That i have lived wit= h and the regular replacement of of a cylinder =3B of two
=0A= but=2C
=0A=  =3B the problem that causes engines to be overhauled is Lifters and Ca= mshafts.
=0A=
=0A= and=2C
=0A=  =3B =3B =3B =3B =3B =3B =3B =3B Lifters te= nd to have spalling=2C (the erosion of the rubbing surface of the cam follo= wer-lifter) which leads to excessive Camshaft wear.=0A=
=0A= and ironically=2C this wear is less likely in an engine that has been used = a lot and regularly. or to wit. a high time engine.
=0A=
=0A= i am intimately familar with this problem because=2C recently=2C a cylinder= removal led to examining lifters which led to having to overhaul an engine= that had 850 =3B hours TT. the engine had been installed in the late 9= 0's
=0A=
=0A= yes=2C
=0A=  =3B =3B =3B =3B =3B =3B it was out of Calender tim= e...which i ignored when i bought the airplane.
=0A=
=0A= how to prevent this problem=2C fly a lot=3B and starting the engine and run= ning it once a month is not a good solution and may exacerbate the problem.=  =3B it is the buildups of moisture and acids in the engine over time t= hat leads to these failures
=0A=
=0A= Conversely=2C
=0A=
=0A= CapeAir=2C has over 150 Continental TSIO520's that have FAA approval for a = TBO of 2=2C500-2=2C700 hours=2C because of the high utility of the aircraft= .
=0A=  =3B (yes=2C that FAA)
=0A=
=0A= and=2C the aircraft that were used for fish spotting in the northeast were = going 5=2C000 to 6=2C000 hours between overhauls=3B those planes were often= flown 10 hours a day=2C day in and day out.
=0A=
=0A= so Calendar time matters=2C for me three time
