Default DAR Inspection - what to expect?

I have read that differenct DARs take different approaches to their inspections. I will be inspected in two weeks and would like to hear about your DAR experience and maybe some "common errors" or any changes/fixes that your DAR required prior to 1st flight. thanks, jack RV9A

I had the FAA do my inspection. It's free if you can get them to do it. Anyway, here's what I did:

Have all your paperwork ready

Have an inspection check list ready

Have all your builder logs, engine log, prop log, POH, A folder with all your manuals and certs for your equipment installed. Any inspection sheets from your Tech Counsellor. Display these near the plane.

Have your flight testing plan made out and available.

Have all the removable inspection covers off, cowl off, seats out, carpet out, covers off, basically everything off and open like an annual inspection. Neatly display all the items removed.

Have the plane and surrounding area as neat and tidy as possible.

Be proffesional, accommodating, helpful, but don't volunteer any info not asked for.

Have coffee and cringle or danish.

You should have gotten an amateur built package from the FAA. This will be helpful in getting everything ready.

All these things help show the inspector the detail and depth of thought that went into your building process and test flying plans. The more organized and professional you look, the less likely you will be scrutinized and nitpic'd unnecessarily by the inspector.

Hope this helps,

Roberta Hegy,
Been there, twice!!

Lightbulb DAR checklist (VERY long)

I have attached a checklist of items needed to issue a Special Airworthiness Certificate to an Amateur Built experimental aircraft. Please make sure that fuel grade and QUANTITY at the fuel tanks, Left, Right, Off or On / Off fuel selector labels, on / off on electrical switches, and a few other required labels that I am finding are getting missed by builders.

A sample Program Letter can be found in AC 20-27F APPENDIX 13.

The application for airworthiness and the Eligibility statement can be downloaded. The Eligibility statement (FAA Form 8130.12) is required to be notarized.

Here are links to the forms that will need completed.
Application for Airworthiness Certificate FAA Form 8130-6

Eligibility Statement FAA Form 8130-12

A good FAA Link to info on Amateur Built aircraft can be found at:

AC20-27F, Certification and Operation of Amateur-Built Aircraft, This AC provides information and guidance in the building, certification and operation of amateur-built aircraft.$FILE/AC20-27F.pdf

AC90-89A, Amateur-Built Aircraft & Ultralight Flight Testing Handbook, This AC sets forth suggestions and safety related recommendations to assist amateur and ultralight builders in developing individualized aircraft flight test plans.

There is also a lot of good information on licensing your homebuilt in the EAA Members Only section under Homebuilders. They have a section on registering and Testing your homebuilt aircraft.

Here is the Checklist to get an airworthiness certificate for your Amateur Built Aircraft:

At the time of application for your Airworthiness Certification ?
(a) The aircraft should be complete in every respect, and?
(b) The Applicant must submit all required documentation.

The aircraft must be in a condition for safe operation for the issuance of an Airworthiness Certificate.

The following must have been done.
[ ] Construction log for the project, photos taken during construction, and log entries describing inspections must be available. (FSDO will also want to see this to get your Repairman Certificate)
[ ] Instrument markings and placards required by 91.9 are completed.
[ ] Labels on fuel grade and QUANTITY at the fuel tanks, fuel selector labels, on / off electrical switches.
[ ] The marking requirements of FAR Part 45 have been complied with, including permanent attached of a fireproof aircraft Identification (date) plate, permanent application of appropriate Registration marks, and the word EXPERIMENTAL near each entrance. [See FAR 45.22 (b)(1) for exemptions. Be prepared to SHOW for allowed deviation with copy of documentation.]
[ ] Passenger Warning placard displayed in the cockpit in full view of all occupants (not required for single-place aircraft).
[ ] TSO-C91A ELT installed 91.207 (except single seat)
[ ] Pitot / Static Transponder test completed (91.413)
[ ] Aircraft logbook, Engine logbook, and propeller logbook are available. (3 separate logbooks recommended but not required)
[ ] A condition inspection in accordance with the scope and details of Appendix D of FAR 43 has been completed by the owner / builder and an entry made in the aircraft log recording the inspection with the following or similarly worded statement. ?I certify this aircraft has had a condition inspection in accordance with the scope and details of Appendix D of FAR 43 and has been found in a condition for safe operation.? The entry will include the date, the aircraft total time in service, and the name, signature, and certificate type and number of the person performing the inspection. This condition inspection does not need to be done by an A&P. The Owner / Builder can do this inspection.
[ ] If a 25 hour Phase I test period is desired, a certificated engine and prop combination must be used. The owner / builder must show and the FAA must find that the engine and prop meet their Type Certificate and all ADs are complied with. (Please include a copy of the compliance list to show compliance with Type Certificate.)

Required documentation:
[ ] Original Application for Airworthiness Certificate FAA Form 8130-6, completed in sections I, II, and III. (Sign in blue ink)
[ ] Original Eligibility Statement FAA Form 8130-12 completed in sections I, II, and III and notarized in section IV. (Sign in blue ink)
[ ] Copy of a three-view drawing or photographs of the aircraft as required by FAR section 21.193.
[ ] Copy of the Weight and Balance to include most forward, most aft, gross weight CG and first flight calculations.
[ ] Copy of Registration AC Form 8050-3.

[ ] Copy of flight test program to show compliance with 91.319(b). (Use AC90-89A as a guide)
[ ] Program Letter

Will make one more post with a check list that one DAR uses on RVs. This is TOO long to post with it pasted in here.

Hope this helps.

(Signature, FAA/DAR)

8130-6 VII J. Airworthiness Certificate issued in accordance with 21.191 (g)

Notes and comments:
3 logbooks (airframe, engine, prop) are not required but ONE logbook is. I recommmend 3 in case you ever swap engines or props.

FAR 91 requires that Transponder and encoder be tested.
Altimeter / Encoder / Transponder ( 91.411 and 91.413 (a) or (b) )
There is really no place in the regulations that require that this be done for the initial airworthiness inspection. FAR 91 requires that it be done to fly any aircraft that has the equipment every 24 calendar months.

The notes about lubing the Hartzell prop is for reference.

ELT is required in 2 seat aircraft.

Items that are not on the aircraft or not applicable are not checked off or are crossed off. Items can be written in if something different is seen. Most of the info from the checklist is transfered to FAA Form 8100-1 for the OFFICAL FAA Record of the inspection after the DAR returns home.

I above checklist was created in EXCEL and is available in PDF format. This is what it looks like after 11 AB DAR inspections over the past 10 months.

Default may depend on you and the acft

My inspection took 1 hour and 10 minutes, including paperwork. Same inspector has taken over half day on other RV's. If you have any doubts about passing inspection, due to "possibly substandard", or just plain ugly work, it will most likely take longer, as the inspector will have more serious doubts as well. By all means, have as many other builders check your plane first, and you can most if not all the gigs taken care of before the REAL inspector gets there! If you have the safety wire wound incorrectly, for instance, he will be looking much more closely at everything else. I was gigged for no weight limit placard on the baggage compartment.

Ask around your area about DAR's, I got a HUGE test area, as opposed to a -4 from Ohio, or Iowa or somewhere, where he basically had to do steep turns for 40 hours to stay in the test area. You would think it would be obvious that an RV needs more space to really test the acft than, say, a Kitfox.

Default DAR inspection

What typically needs to be off for the DAR inspection?
Floors? Cowls? Wing root fairings? Empennage fairings?
Baggage compartment?

When the FAA does the inspection, all they require is for the cowlings, fairings, and inspection plates to be removed. I would not disassemble the interior and remove any floor panels, seats, etc.

I've been through this twice before and that's all I did. Now, I've heard that some of the DARs go way beyond that. Personally, I'd check with your closest GADO and see if they will do it before paying a DAR.
