(g) Required Actions
(1) At the next oil change or within 4 months after the effective date of this AD, whichever occurs
first, and thereafter at every oil change until the bushing replacement required by either paragraph
(g)(3) or (4) of this AD is done, perform a visual inspection of the engine oil filter, oil pressure
screen, and oil suction screen (depending on the engine configuration) for bronze metal
particulates. The actions required by this paragraph may be performed by the owner/operator
(pilot) holding at least a private pilot certificate and must be entered into the aircraft records
showing compliance with this AD in accordance with 14 CFR 43.9(a) and 91.417(a)(2)(v). The
record must be maintained as required by 14 CFR 91.417, 121.380, or 135.439.
Interesting. I believe "screen and filter" is actually listed in the preventative mx listing. Don't see how pilot could legally perform a regular oil change without checking those items? Regardless, must be an issue to require check every 25-50 hours.Normally it's regarded that only an A&P mechanic can do an oil screen/filter "Inspection".
I'm not sure I understand the "Moss Interpretation" but, it was taking 43.3(a) to the extreme. Including an A&P Student and Owner/Operator Preventive Maintenance privileges. The Savvy videos I watched, they said that only an A&P could do inspections in person as per the "Moss Interpretation". Don't ask me what's going on it seems like typical bureaucrat trying to justify their importance silliness. Maybe Mike Busch is just trying to make something from nothing?Interesting.

43.3 Persons authorized to perform maintenance, preventive maintenance, rebuilding, and alterations.
(d) A person working under the supervision of a holder of a mechanic or repairman certificate may perform the maintenance, preventive maintenance, and alterations that his supervisor is authorized to perform, if the supervisor personally observes the work being done to the extent necessary to ensure that it is being done properly and if the supervisor is readily available, in person, for consultation. However, this paragraph does not authorize the performance of any inspection required by Part 91 or Part 125 of this chapter or any inspection performed after a major repair or alteration.
(23) Cleaning or replacing fuel and oil strainers or filter elements.
Moss LOI was rescinded so its moot.I'm not sure I understand the "Moss Interpretation"
Key part. For Part 91 this statement applies to inspections required under Subpart E. It does not apply to checking/inspecting the filter or screen during a pilot Part 43 authorized mx task. If he didn’t follow the OEM guidance to check the screen or filter then he would be in violation of Part 43.13.the performance of any inspection required by Part 91
Follow the Lycoming Bulletin referenced in the AD:So, as an owner of an O-360-A1D, how does one most easily inspect specifically for bronze particles in the filter?
Absolutely—I just broke open my engine log to verify the part numbers and I’ve got affected parts in the date range on my IO-540.Also watch the manufacture/delivery dates, which range from 2009 to 2017 depending on model. Outside that range, you're fine.
How does that work? I had a new engine installed in March 2018, the engine build is dated 1/11/2018. The latest date in the AD is 2/14/2017 and my engine was built and delivered almost a year later, so mine is probably out of scope? I have no record of the part numbers for the con-rod bushings, or for any other internal parts. Is that something one gets from Lycoming by sending them your engine serial number?Absolutely—I just broke open my engine log to verify the part numbers and I’ve got affected parts in the date range on my IO-540.
My engine builder provided me a list of the parts they used when they rebuilt my engine off an old core as part of my documentation packet. 4 of my 6 connecting rod assemblies fall squarely in the date range. 2 are outside the range as they were replaced later during a tear down after an overspeed incident and they discovered damage from a tappet that self destructed.How does that work?

Since your engine was overhauled by Penn, give them a call and see if they still have the workorder or build sheet for that engine. As there's only a requirement to keep CRS records for 2 years, some keep them and some don't. If you ever get an engine direct from Lycoming or TCM, you can give them your S/N and they will send you a copy of the build sheet. And as a note, there are only 2 regulatory terms when it comes to engine work: overhauled or rebuilt... and only the OEM (or their agent) can rebuild an engine.PS: it's an O-360-A4M built by Penn Yan
One exception—if you can fly with a non-certified, experimental engine (which I can) it can be rebuilt by a builder and zero timed with a new data tag.Since your engine was overhauled by Penn, give them a call and see if they still have the workorder or build sheet for that engine.

True. But its not an exception as the Part 43.2 regulation doesn't apply either.One exception—if you can fly with a non-certified, experimental engine (which I can) it can be rebuilt by a builder and zero timed with a new data tag.
