Agreed, the first 100 hours are all a test flight for
material and workmanship.

| Hello All,
| Where I fly, the density altitude on the tarmac is
typically more than
| 7000ft even on cold days (9000ft on hot days). As a
result, non-turbo
| engines cannot develop any more than 70% of rated power.
|
| The consensus around here is that as long as the engines
are blessed by
| the mechanics and checked for compression, one can
exceed the
| recommended TBO sometimes by a factor of 2x.
|
| My question is this: Is this practice safe? What about
material fatigue
| in the engine components (i.e. crank shaft, pistons,
rods, valves etc)?
| Would this practice make the chances of an engine
failure more likely?
|
| Thanks.
|
|
| I would rather fly a over tbo engine with a clean bill of
health & good oil
| analysis trend than a freshly overhauled or factory new
engine with 0 hours!
