Today, I was walking a student through determining whether a particular piece of equipment is required by the regs for flight (i.e. 91.213). I used the flow diagram in AC 91-67 ( page 13 of http://rgl.faa.gov/Regulatory_and_G...4a06437c5fa862569d900744d86/$FILE/Chap1-2.pdf) to walk him through it. I stumbled a bit on explaining equipment being required "by the VFR type certificate requirements prescribed in the airworthiness certification regulations" (91.213 (d)(2)(ii)

Anyone have an example of when this is applicable?

Carb heat, stall horn (part 23) or any other item under part 23. Interestingly stall horn is NOT required under CAR part 3. So an older Citabria is perfectly legal without a stall horn and normally does not have one. A new Citabria has a stall horn.
Touched on before, but I'll post again. "Them mechanic told me it was okay" is not a valid excuse.

Oh... almost forgot. If there is an STC the STC must be complied with as well in order for the airplane to be airworthy- this is part of it. Most common thing I see is autopilot installed without the manual; STC that requires new placards, but no placards installed. Technically the airplane is not airworthy.

I knew an IA once who had pretty much no idea about any of this. Scary.

I call this the Type Certificate Data Sheet (TCDS). It is a list of equipment required under FAR's at time of certification.
A real live example to me is a shoulder harness. They weren't required when I first started,..so, you have to look at the TCDS for that airplane to check (d)(2)(ii).

Where in the TCDS does it say what equipment is required? If I pull up a TCDS for the PA-28, it just gives general engine/aircraft/propeller data, and other specifications.

No, it gives very specific information on the engine/propeller data. If the propeller is not listed on the TCDS, for example, you must either have an STC or field approval for the propeller.

Type Data sheet may require a POH in the aircraft, and in that POH will list required equipment. If the equipment is not in the POH or TCD you will need an STC.

PA-28 TCDS said:
The basic required equipment as prescribed in the applicable airworthiness regulation (see Certification Basis) must be installed in the aircraft for certification. In addition, the following documents are required:

The documents are the POH, AFM, and supplements. You'll have to check those for equipment requirements if the TCDS doesn't say.

Some TCDS will list all required equipment. Take a look at the PA-23-23. I'm not sure why it's different. I think it could be because the TCDS is older, and the aircraft was certified before the time of the FARs.

Thanks for the explanation. Makes sense to me now.

I have not looked at the PA-23-23 TCDS. Some airplanes were certified under CAR part 3. If that is the case then that is the applicable airworthiness regulation.
