Not necessarily true. Can you provide a reference that a mechanic only has to follow a maintenance manual that was produced when the aircraft was manufactured and that revisions are not mandatory? Also, if Cessna revises the TCDS and places these inspections in the "Limitations" section they now become mandatory irregardless of the type of operation. Notice 43.13 says "current manufacturer's maintenance manual".

43.13 Performance rules (general).

(a) Each person performing maintenance, alteration, or preventive maintenance on an aircraft, engine, propeller, or appliance shall use the methods, techniques, and practices prescribed in the current manufacturer's maintenance manual or Instructions for Continued Airworthiness prepared by its manufacturer, or other methods, techniques, and practices acceptable to the Administrator, except as noted in §43.16. He shall use the tools, equipment, and test apparatus necessary to assure completion of the work in accordance with accepted industry practices. If special equipment or test apparatus is recommended by the manufacturer involved, he must use that equipment or apparatus or its equivalent acceptable to the Administrator.

Once again it boils down to the mechanic signing off the inspection.....if the aircraft is later involved in an accident or a certificate action and the mechanic did not follow the MM his liability has now increased dramatically.

43.16 Airworthiness limitations.

Each person performing an inspection or other maintenance specified in an Airworthiness Limitations section of a manufacturer's maintenance manual or Instructions for Continued Airworthiness shall perform the inspection or other maintenance in accordance with that section, or in accordance with operations specifications approved by the Administrator under part 121 or 135, or an inspection program approved under §91.409(e).

Also, under the FAR's the owner is responsible to insure all maintenance and inspections are done and properly documented. Do you as the owner want to risk yourself by not following a maintenance manual? Ask an attorney that question.

At last year's IA seminar the head FAA maintenance guy told this to the group, "that the only required maintenance manual is the one at the time of production." This is very applicable to much older airplanes certified under CAR, like the Skymaster was. The key word is "required" that doesn't stop any one from using new data however. I'm sure the reference was in an FAA or NTSB ruling, but since you asked I guess I'll have to search for it.

Curent means "current at the time of manufacture" as pertaining to part 91. Period .

Roger, this is precisely the reference we needed. It's required reading for all Part 91 users curious about SIDs. This won't happen, but this discussion on SID applicability to Part 91 operators could end right here.

The problem lies in that the letter references only large or turbine powered aircraft, which are not applicable. Ref 14CFR91.409(f). The letter speaks of the current inspection program, not maintenance manuals.

14CFR43.13 is still applicable in that para (b) specifically addresses structural strength and deterioration.

You don't have to convince me, you have to convince the guy making the release for service entry in your maintenance records.

If for some un God reason that you happen to crash a month after I perform an inspection on your airplane, and do not comply with the SIDS, and a wing or boom is not attached to the wreckage, your heirs attorney is going to have a field day explaining to the jury that I did not comply with the manufacturers recommendations on keeping up with airworthiness standards on an airplane that they designed and built.

Good catch. I went and read 91.409 (f)(3) and you are correct, it only applies to turbine aircraft.

I am an IA, before I would release the aircraft, I would need to comply with the new standards. I have a very good attorney, but he is not that good with grieving widow, along with clear instructions on continued airworthiness staring at him. In my humble opinion I would comply.

Thanks for the reference.
