Your FAA guy gave you the wrong SB.
The required inspection is the AD and it sites this MSB
You must use Lycoming MSB No. 475C, dated January 30, 2003, to perform the inspections and repairs required by this AD.
The FAA can recommend, they can not dictate over and above the requirements of the AD.
The minimum required maintenance thus the least money spent is compliance with the AD, not a complete tear down, My call would be based upon the engine times, and other conditions of the engine. Does the crankshaft dial out as within limits? No tear it down, you will anyway to replace the crank. If it has no other problems I'd go with the AD compliance.
Did you even read what I wrote? You are quoting things I did not write.
First I started off by writing in my very first post that you were correct, that the tear down is
NOT mandatory. I never wrote that it was. I reiterated
AGAIN in later posts that this was the case.
Second I said nothing about "an FAA guy giving me an SB." I quoted an FAA Special Airworthiness Information Bulletin which I mentioned is
NOT mandatory.
Third, I quoted the AD and SB 475C when I agreed with you.
I then went on to quote the FAA Special Airworthiness Information Bulletin that
recommended following SB 533B. Again, recommended meaning it was
NOT mandatory. Do you understand
not mandatory??
You responded, "If Lycoming believes a complete tear down is not necessary why would the FAA have a problem with it?"
I then asked you how SB 533B (which I know is NOT mandatory- got that?), which is a Lycoming SB (which is NOT mandatory if I did not say that), is not a tear down inspection.
Now I understand that this SB is not part of the AD and is therefore
NOT mandatory, but since it is recommended by the FAA to follow it and if it is put out by Lycoming how can you say Lycoming does not believe a complete tear down is necessary? Although
not mandatory if I did not mention that.
So my question again is how is this non-mandatory SB from Lycoming not a tear down? I am only curious as, though it is
NOT mandatory (if I did not mention that), it
IS recommended by the FAA that you follow this Lycoming SB. And again, my point in providing the link was to show:
A. Why I thought a mechanic might be put in a liability bind by not following the FAA's and Lycomings recommendation (not mandatory).
B. Why I would walk away from an airplane for sale where the FAA's recommendation on maintenance -again,
not mandatory if I did not say that- was not followed.
But again, my question is how the
non-mandatory,
not required but recommended SB 533 is not a tear down?
