:)
it was only clarified in discussions with the factory, so nothing written. A revision will be made, soon.
-The time is not added to your current calendar time, if the engine is 20 years old it does not get an additional 3 years if you comply with the SB.
Sir,
I have one 914 F, 12 years life about to complete ,TBO is very closed. But situation is that it run totally not more than 150 hrs in 12 years of Life.
I have checked in detail the crankshaft out of roundness.The data is 0.10 mm. (I am lucky)
As no legal requirements about flights ,. can we Fly up to 100 hrs more or 1-years?
The crankshaft out-of-round limit is 0.080, so you are slightly out of limits.
The legal question can only be answered by your countries civil aviation authority.
In Canada you can go on-condition, forever if the engine passes all the criteria (such as compression, power, no significant oil leaks...
See BO41 https://www.tc.gc.ca/eng/civilaviation/standards/maintenance-aarpc-ans-b041-549.htm
But you have to implement the on-condition program well before TBO to establish a baseline.
another engine checked today and found the crankshaft out of roundness.
The value is 0.04~0.05 mm. Total run time is 120 hrs in 12 years.
All other maintenance was carried out on time, like Oil + oil Filter change, 05 years Rubber parts replacement.
Cylinder pressure test found OK and Oil consumption is ok, as per Book.0.06L/h .
what you suggest for next 06-monts/ 0r 100 hrs extension?
please comments...
