Thank you for your prompt reply.
Some service bulletins are not serial number specific, i.e. they are applicable to all engines, e.g. all 912 S engines. Can I assume that any service bulletin issued prior to the engine manufactured date does not apply to later engines, i.e. only service bulletins issued after the date of engine manufacture are applicable?
In other words I assume that any issues discovered and then notified through service bulletins are addressed/corrected so that engines manufactured and released after that service bulletin are unaffected, e.g. Service Bulletin SB-912-042 only affects engines manufactured prior to April-2004 and therefore not applicable to engines manufactured after April 2004?
