91.213 - Equipment List - Static Wicks - C172S

[CC268]

Studying up on 91.213. Was curious as to whether or not static wicks were required. It's not listed in the Kinds of Operations Equipment List, not required by 91.205, not required by an AD, and I couldn't find anything in the TCDS about it either. However, it does show up on the Equipment List in Section 6 of the POH.

Suffix letters as follows:
R = Required items or equipment for FAA certification (14 CFR 23 or 14
CFR 91).
S = Standard equipment items.
O = Optional equipment items replacing required or standard items.
A = Optional equipment items which are in addition to required or
standard items.

The static wicks are marked 'S' for Standard equipment. However, I can't seem to find anything that states whether or not Standard equipment is required or not? (e.g. can you fly if your missing one static wick?)

Per 91.213, since it's not listed in 91.205, not in the KOL, not specifically listed as "Required" in the POH, and there's no AD requiring its installation, assuming we're talking about a light, non-turbine powered airplane, it seems the A/C would be legal to fly. Just make sure to enter it into the maintenance log.

It would be interesting how one would comply with the "deactivate and placard as INOP" part of the regs though.

Yea but your missing the fact that is listed as a Standard item in the Equipment list. I guess my question is...does standard mean that it is required? Obviously if it is labeled 'R' for Required it is...but what about standard?

Lol I can totally see an examiner asking me about this on my Comm. checkride so I want to make sure I completely understand this.

 

[bflynn]

It is installed standard with every aircraft. It is not required for a particular flight operation.

Ahh okay your second sentence helps clear up my question.

The way I see it, "Standard" =/= "Required". Standard just means the plane rolls off the assembly line with the item installed.

You're right that the examiner will almost certainly ask about Airworthiness/INOP equipment on the Comm. checkride. I would refer you to www .flywithhoward.com/resources. Check out the powerpoint named "Understanding Airworthiness". Best explanation of the topic I've seen, and it's straight from a DPE.

mmmmm.... Not so sure about the "every aircraft" claim ..... Many Bonanzas, including our Club's 1966 V35 don't have wicks. Investigating the question on Beechtalk supported what I learned.

He was referring to Equipment List section in the POH (Section 6), specific to the C172S - which lists equipment with a suffix (R, S, O, A).

I think he means standard for that particular model as stated in the POH

Gotcha.... I read it as a "broadbrush" for all GA aircraft

 

[JAWS]

Standard for that Cessna model when built. Think mudflaps.

Mudflaps...what you get when you operate off a dirt strip in the rain?

Standard equipment is not required, but if it is removed it needs to be logged and the equipment list updated.

Thanks for the link that explains it so much better.

I recall there being some short ground straps that were braided or woven, and that connect the flaps and elevator to the rest of the Cessna 172 airframe.

What are they officially called? Ground straps? Static wicks? Something else?

No this isn’t the ground straps

I meant more in terms of a car. Cessna puts what they call standard items on their aircraft, just like Ford with their F150's. Some car manufacturers include nitrogen in their tires as "standard".

 

[bflynn]

Standard equipment is not required, but if it is removed it needs to be logged and the equipment list updated.

I don’t think I have ever seen an entry for a broken static wick.

 

[Clip4]

. Broken is not removed. If it was removed there should be an entry. Example would be rear seat, standard equipment if removed needs an updated WB and EQ list.

I've never seen log entries for a lot of things that should have log entries.

 

[Richard cfi]

This is a subject that several of us cfi’s have been discussing. It was brought up because a DPE failed a checkride because one of the visors was taken off due to it being broken. I am confused as many of you are between the required and standard equipment. When reading the equipment list in the POH, it also lists a fuel tester cup as standard equipment...so does that mean if it doesn’t have the same type of fuel tester that came with the plane, it isn’t airworthy?

Should have slapped a Post-It note on the stub of the visor saying inop. Sounds like a b s bust too.

was there a logbook entry?

 

[EdFred]

See that's where things get stupid. Why should there be a logbook entry for a non-essential piece of equipment? My hand rest broke in my airplane and I fixed it with some Gorilla Glue but I'm not going to bother with a freaking logbook entry for that sort of crap. It's completely non-essential.

"Oh, you put the N number on the panel with some label tape you didn't make a logbook entry for it looks like the airplanes not airworthy."

 

[Tom-D]

The aircraft is not fully equipped as per its production certificate for that model. So it becomes a issue of properly altered condition.
It would be a decision for your IA, Is it a major or minor alteration to remove them.

A very clear explanation of the probable reason for the bust.

Which is why I think the whole thing A/W can get stupid. None of those things have anything to do with the actual airworthiness (read as safe to fly without incident or flight characteristics) of the airplane. A broken armrest doesn't affect flight nor does a piece of tape on the instrument panel or a missing sun visor as a lot of planes don't have any of those and any plane that had them removed would still be perfectly safe to fly without incident.

And the place to make that point is on a check ride when you're specifically supposed to show knowledge of and
compliance with airworthiness regs.

What an applicant does when the aircraft discrepancy is pointed out normally determines whether it's a discontinuance or an UNSAT.

Take a brand new _______________, the aircraft with the life rafts, life vests and life line installed is certified to 25.801 Ditching, does all that equipment have to be board during all operations?

If yes, what if any one item of that equipment is passed due for inspection? Each vest, and raft have an expiration date on them.

You should be around corp jets, where there are more seats in them than can be legally occupied for takeoff and landings. Some of those seats change depending on whether or not certain equipment is install/removed.

I don't fly part 25 aircraft. I don't recall a 172 being part 25 either. That's like applying part 121 regulations to part 91 burger runs.

You'd have to read the specific airplane's documentation.

Lotta Part 25 aircraft are operated 91 everyday

 

[EdFred]

Lotta Part 25 aircraft are operated 91 everyday

172s with broken static wicks?

 

[bnt83]

probably the most common missing equipment on GA aircraft is the baggage net.

 

[MauleSkinner]

Lotta Part 25 aircraft are operated 91 everyday

And how many of those defer items per 91.213(d)?
