ADs that Homebuilt Must Comply With

[gmcjetpilot]

Been awhile since I researched that. My understanding is if you have a certified appliance (engine, prop, carb, mag) that has an AD you are obliged to comply (based on opinion not facts). The out is to take the data-tag off and make it "experimental". This is a can of worms.

Agree, that?s exactly how I?ve been told.

The problem I see is that many of the engines in RV's, especially the older 4/6's, have engines that have Lyc data plates, but the history is 'questionable" and there is no easy way to determine what's inside or if any AD's were ever complied outside of a complete teardown.

This argument has been around for as long as Experimentals, with probably just as many opinions as there are airplanes and owners, and everyone can find some "data" somewhere to back up their opinion.

The reality is that someone has to sign off the Condition Inspection each year with a statement that it is in a condition for safe operation. I wouldn't want to be the person who signed it off knowing there was an AD, such as the oil pump AD, and then someone got hurt or killed as a result of that.

AD's are not issued against Experimentals, but some of the manufacturer's SB's come pretty close, especially when they say "prior to further flight."

While we might choose to ignore them or not comply, I bet if you asked your passengers they might have a different opinion.

Here is a real example: The Lycoming 2017-16-11 AD references MSB 632 B which includes experimental engines (Table 1) and parts that may have been installed in experimental engines (Table 2).

From the AD:

(c) Applicability
This AD applies to:
(1) All Lycoming Engines reciprocating engines listed in Table 1 of Lycoming Engines Mandatory Service Bulletin (MSB) No. 632B, dated August 4, 2017, and
(2) all Lycoming Engines reciprocating engines that were overhauled or repaired using any replacement part listed in Table 2 of Lycoming Engines MSB No. 632B, dated August 4, 2017, which was shipped from Lycoming Engines during the dates listed in Table 2 of Lycoming Engines MSB No. 632B, dated August 4, 2017.

(g) Required Actions
(1) For all affected engines, within 10 operating hours after the effective date of this AD, inspect all affected connecting rods as specified in Lycoming Engines MSB No. 632B, dated August 4, 2017, except for the instruction to complete the online survey and the instruction to review your inventory.
(2) Replace all connecting rods that fail the inspection required by paragraph (g)(1) of this AD with parts eligible for installation.

So, in this case, if you have a listed engine (experimental or not) OR an engine that may have these parts (your "SOGO 22") you are still required to comply with the AD according to AC 39-7D. Correct? I guess you could argue about whether your "SOGO 22" is a "Lycoming Engines" engine or not..

Legally speaking, the SOGO 22 is not a Lycoming engine and not subject to the AD.

Reality and a good sense of your own mortality may convince you to pay attention to it anyway, but you are not required to. There are many, many things in the E-AB world that fall under "Just because you can, doesn't mean you should."

IMHO this applies to life, not just the E-AB world.

Ed, when I changed out my Lycoming O-290D2 for the ECi O-360 I did not have to get another inspection or new Operating Limitations, pernmy paperwork and the Charlotte FSDO; however, I did do that and put it back into phase 1.

My ECi engine is not subject to Lycoming AD's but you can be sure I check ECi's website!
