Certificate experimental aircraft
get a special C of A, the limitation and use

Subject: aircraft paperwork

(First we focus on the requirements for the USA. Canada will be next and for other countries we encourage everybody to go already ahead and maybe write something. We will publish it here and if it is a French, German or Spanish text we offer to translate it.)

We all love to fly. And maybe we want to fly something a little different than the standard C172 or standard PA28.
(nothing wrong with them !)

Why this is a problem?

The very simple answer; if it is not standard it is special.

Aircraft have to be registered or you can call it immatriculated what gets them a nationality, a call-sign and a owner. This is the first step but like this they are not flyable.

(a while ago we were joking what Oklahoma (the FAA-registry) would say when trying to register a Saab 900.

MANUFACTURER: Saab

MODEL: 900

but maybe they find out what it is when mentioning convertible)

To make it now a real aircraft we need a certificate of airworthiness that is issued by the FAA- FSDO or MIDO. To make it less confusing a standard aircraft gets a standard CofA and a special aircraft gets a special one. If you don’t like the engine of your standard Cessna change it and this makes it "special". Or build your own plane and this is special.

A FAA – inspector or a DAR (designated airworthiness representative, he's doing the same work but charges some money) has to see the aircraft and the accompanied documents and hopefully will give out a special CofA.

In this CofA the Aviation Administrator regulates the uses of special planes. We assume that the only reason and measurement is the safety aspect. These aircraft do not have a type certificate or not the correct one what equals, the safety is not confirmed.

(there are a lot of pilots, not understanding the difference between demonstrated safety by a track record or a confirmed safety of complying with the type certification requirements)

To make everybody aware of the special nature the word EXPERIMENTAL has to be displayed on the aircraft.

To call an aircraft "EXPERIMENTAL" and to issue a special CofA a reason is needed. Just to want to fly it isn’t enough and here the FAA will point to all the standard aircraft that comply with the type certification requirements, at least at one day in the past.

There are several categories and lots of reasons to request a special CofA but we concentrate here on exhibition/air-show.

The exact procedures are given in order 8130.27 (see below) but final decisions are made by the FAA inspector. The guideline for national standardization is given and all aircraft are squeezed into one of four groups.

  • Aerobatic aircraft are placed in group I.
  • Ex-military jets are clearly in group II.
  • Smaller warbirds are in group III.
  • Larger aircraft and conversions from standard aircraft are group IV.

Take this as a basic structure were the fine print reads it a little different and gives some room for own interpretations. These interpretations can see a certain aircraft in another group, but like sad before the FAA-inspector has to share that view.

So what, group I or II or… why it is so important?

The FAA created a whole catalog of limitations and depending of the group some limitations apply others not. Basic requirements are the same for all and is related to the status of experimental aircraft.

Now the operation requirements are divided in two parts called phase1 and phase 2. What is a test-flight period and a normal operation period. And even here the given standards are not absolute. Some aircraft never saw a phase 1 because they are fairly normal aircraft or they came into the country by air. Even the FAA accepts the demonstrated safety of operation when a aircraft just came across the pond.

Before listing now all these limitation- requirements it’s important to say that the reality and the written order differs sometimes a little. The reason, most pilots and people involved have more than average experience in total flight hours and in years in aviation what gives them knowledge and superiority how to handle and sometimes circumnavigate the FAA orders. But one example: first we read the text that is part of the introduction of order 8130.27 and than you look in trade-a-plane to see the reality.

7. Brokering. Section 21.191(d) was not intended to allow for the brokering or marketing of experimental aircraft. This includes individuals who manufacture, import, or assemble aircraft., and then apply for and receive experimental exhibition airworthiness certificates, so they can sell the aircraft to buyers.

Take now one issue of T-a-P (use the paper version in cyberspace you will get gray hair) and look up all the dealers in the warbird or experimental section. How you want to stop somebody to do business, specially in a country like the United States.

(talking with owners is the best source and here we are not going to stress this part unnecessarily)

But the same is true for FAA inspectors that not always follow the text word by word as given. Taking time picking one can make the difference.

If he likes aircraft (what is not automatically confirmed when working for the FAA) or even better if he is flying it definitely helps.
