Cessna C337 SID

As an A&P IA, today's part 91 Skymaster could be tomorrows part 135 car parts hauler, and the same annual inspection is still valid in both cases.

No need to. The Part 135 cargo/on-demand is just an example. The Final Rule applies only to Part 121, multi-engine Part 129 and multi-engine Part 135 (with the Part 135 exclusion mentioned earlier). It does not apply to Part 91. Period.

What I'm saying is that I could perform an annual inspection on a Skymaster today, the owner sells it tomorrow, with a fresh annual, and the new owner puts the aircraft on a 135 certificate the next day.
The annual that I performed is still in effect, and not due for another 12 months.

True. But in order to put the Skymaster on a Pt 135 Certificate requires a "Conformity Inspection" by the FAA. In order to comply with a conformity inspection all SB's must be complied with.

But the SID is not a service bulletin.

Not at this point. But the FAA PMI could require that SID's also be complied with for a Part 135 certificate. Right now all of this is in unknown territory.

Just a point of order. There was a question asked "Are inspections for continued airworthiness the same as SIDS?" The answer is not just no, but what is an "inspection for continued airworthiness?" The answer is: inspection for continued airworthiness is either listed on the aircraft's type certificate or in the maintenance manual (and is referred to by the aircraft's type certificate). For example, a new Cirrus maintenance manual may have a section called "instruction for continued airworthiness." And in that section it might say every 5,000 hours to replace the windshield. In this case, it is mandatory!!!!!

That's why I said the only required maintenance required, other than ADs or FARs, is the maintenance manual on the day the aircraft was produced...at least for part 91. So, if Cessna makes a new maintenance manual for the Skymaster with a section for continued airworthiness then you are not obligated to follow it...at least under part 91.

On a side note, if you have a Supplemental Type Certificate, such as paper oil filters then there may also be an Inspection for Continued Airworthiness listed in the STC instructions. In that case the Inspection (or instruction) for Continued Airworthiness is mandatory since the STC modified the original aircraft's type certificate.
