Trace and
Airworthiness Issues are Separate and Distinct
Don’t you
hate all those Latin terms that continue to linger in our language
such as “pro Bono”, and “Quid-Pro-Quo” (isn’t that a fish
delicacy in some parts? I’ll eat it if I don’t have to look at
the eyes)? One that I must use with some regularity is “De Facto.”
De facto is a Latin expression that means "in fact" or
"in practice" but is not spelled out by law. Our industry’s
current requirements for traceability are not clearly or overtly
codified in any body of regulations, but one actuality remains
indisputable; traceability has become de facto
industry requirements.
A common
recurring concept that I find myself routinely explaining to new
persons (particularly those in sales and purchasing) is that the
issue of airworthiness documentation is separate and distinct from
trace documentation. For example, someone may ask,
“Royboy,
the part I sent my customer had an EASA form 1 with it. Why in the
world did they reject it?”
The part
and EASA Form 1 were pristine. The culprit? Gaps in the Traceability
chain.
“But
Royboy, it has an EASA Form 1 with it; it’s airworthy and ready to
install, what’s the problem?”
As is my Modus
Operandi, I smile, flutter my eyebrows, and launch into
my well rehearsed ab
initio speech. The fact is that many people assume a
part with an airworthiness document (such as a FAA 8130-3 or EASA
Form 1) settles all issues of traceability and documentation; that’s
just non
sequitor. Remember this, you can have a part with
complete trace documents, but if it does not have airworthiness
documents, the part is not ready for installation. On the other
hand, you can have a part with airworthiness documents, but without
complete traceability, most customers with robust Quality systems
will reject the part. One is not good without the other, and must be
treated as separate and distinct issues.
Just a
quick review of what trace is. The definition of Traceability is:
The ability via documentation to track aircraft parts, processes,
and materials by lot, serial number or other means to the
certificated source or manufacturer (ref ATA Specification 106
titled “Sources & Approved Parts Qualification Guidelines”,
Chapter 1, Definitions).
Most
companies accept trace to airlines or repair stations because, as
the definition says, you’d be tracing it to a “Certificated
Source”. Indeed these certificated sources have strict
traceability requirements, so we accept their certificate as proof
that they too obtained the parts from acceptable traceable sources.
Think of trace as a successive and documented chain of custody. For
new or factory new parts, the trace is to the Manufacturer, so that
is easy. It’s not so easy when you deal with parts in the
aftermarket. In this case, the part could have changed ownership
several times, not to mention it’s condition. A thorough
discussion of what traceability is, and what is acceptable is not
the aim of this blog. I just hope you’ve established the
separation of these issues in your business dealings.
By the way,
I’ll have you know that this blog article is a pro-bono
effort on my behalf.
