Form One Questions

The TCDS for my ship simply incorporates the MEL and Equipment
Specifications of the manufacturer by referencing the LS Maintenance
Manual. No worries - my ship has all of the exact model instruments
(with TSOs) that are on the MEL.

What's confusing me is the seemingly arbitrary behavior by LS.
Consider:

1. A TSOed compass is required by the MEL. No compass was installed
by LS, as proven by the signed Equipment List carrying an LBA stamp.
Yet LS delivered a JAA Form 52 that states "it is hereby certified
that this aircraft conforms fully to the type certificated design"
with no exceptions or waivers listed.

2. An OAT is required by the MEL. LS installed one, but delivered no
Form One. Apparently it's not necessary to certify that a required
instrument is airworthy.

Maybe this behavior was caused by problems posed by the impending
bankrupcy of LS?

In the end, for me, flying the ship on an Experimental airworthiness
certificate in the US, none of this matters. For others, in different
countries, such arbitrary delivery of documents might be a big
problem.

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.
