Form One Questions

I’ve got two questions for European pilots regarding the Form One,
arising out of curiosity on my part.

First, it appears to this US pilot that one of the uses of a Form One
is to certify that a new part is airworthy, with the basis for
airworthiness being that the part was made in accordance with a TSO or
some other approved technical specification. Is this correct?

Second, why would a plane made in Europe not have a Form One for all
installed equipment? Isn’t it necessary to certify that all of a new
aircraft’s equipment is airworthy? I ask because my LS8-18 (made in
2000) has Form Ones for the 4-point harness, nose hook, CG hook, main
wheel hub and brake, airspeed, altimeter, VHF radio, ELT and
transponder antenna. No Form Ones at all were supplied for the
transponder, encoder, SN10, Sage vario or VHF antenna. It isn’t a
matter of loss, because I have all of the Form Ones listed on the
original LS document transmittal letter.

Well John..... usually Europe is far ahead of US in most respects, but
you have just discovered one area where we are way behind you
yanks...... our governments just love "bureaucrazy"!

Roughly said, yes. EASA Form 1 ist the exact equivalent of the FAA Form
8130–3, it even has the same blocks. (And EASA honors FAA 8130-3 forms.)

Form 1 (or an equivalent certificate) is only required for required
equipment.

I'm not sure how transponders, radios and ELTs are handled because they
are not required but must be approved somehow.

I have a Form One for both my radio and transponder.

Who determines "required equipment" for Form One? I've got Form Ones
for things that aren't on either the Minimum Equipment List or the
Master Equipment List, while I'm missing Form Ones for things that ARE
on the Minimum Equipment List! Seems very haphazard - maybe it is a
"bureaucrazy"...

You can have your wrist watch TSOed if you wish and pay for it, but it
isn't required.

On the other hand, even TSOed instruments don't nessecairily come with a
Form 1. They most probably will today, but Form 1 is just a standardized
format for describing to which TSO a given aircraft part conforms, but
you can ask the manufactorer to confirm this in handwriting on the back
of a used envelope if you prefer this. This won't make anybody's life
easier, though. And don't forget that Form 1 didn't even exist a couple
of years ago, so the TSO certification of older instrument will most
probably have some random format unless they have been overhauled recently.

On yet another hand, you can even fill out a Form 1 also for non-TSOed
parts, if you like. Just leave block 13 empty or fill in: not TSOed.

Appreciate the additional information, but you sidestepped the
question.

You said earlier "Form 1 (or an equivalent certificate) is only
required for required equipment." I said earlier "I'm missing Form
Ones for things that are on the Minimum Equipment List!"

The MEL defines required equipment, doesn't it? If not, what IS the
definition of "required equipment" used to trigger the use of a Form
One?

Yes, of course. But frankly, I'm no aviation attorney and even if I were
I couldn't comment on a glider I have never seen.

I'm not seeking legal opinions, just understanding. My glider has an
Experimental airworthiness and Form Ones are useless to me. I'm just
trying to understand why LS didn't provide Form Ones for items that
appear to be required, and did provide Form Ones for things that
appear not to be required.

Look at your own aircraft TCDS (type certificate data sheet) and what is
listed as "required equipment"
if is says there an altimeter, then it needs an altimeter.if it says an
altimeter model # ---- or equivilent meeting TSO ---- or ESA ---- ect then
you have to have one that meets or exceeds this standard of certifcation....
if it's not in the "required" instrument list then it isn't needed to meet
the TCDS...
there are really NO flight computers or electric variometers that ahve any
certifications...nearly all Winter Mechanical instruments including
variometers have ESA form one type approvals.few if any others do...PZL's
had some national certifcations but at the time they were most common this
was not recognised outside the old eastern block..today they might (not
sure, we really don't see many new PZL's) same for many others...obviously
PDA's, ClearNav's ect have no approval certificates at all but you will find
them common in gliders...they are simply "not required" by TCDS...this
however does not mean that just anyone can install them in any way they
want.the installations still have to be performed in such a way as outlined
in AC4313.....log entries, Wt/Bal ect still has to be performed, aircraft
type hardware, cables ect also should meet AC4313 ect.
you'll get unfortunately different answers from mechanics and even
(especially) the FAA inspectors themselves....so it does tend to remain
"grey" and subject to the that one paricular official's interpetation.
