Hi Prof. Ed,

You continue to show unusual ability to cut through the BS and get to the "meat" of the matter.

In my opinion, which is worth what you pay for it  ;<)   that is this:

1.  "We", as in Ercoupe owner/operators want to know two things:

a. What was the "root cause" of the in-flight catastrophic structural failure of the wing
                structure of the 415-D in the 12/8/08 accident in Sebring, FL.

        b.  Is this "root cause" present in our owned aircraft.

2. If you take "We" from the perspective of the NTSB, it would appear that no final report on this accident has been issued because the information they have in the context of what they "know" is not yet sufficient in their opinion to be conclusive as to a "root cause".

3. If you take "We" from the perspective of the FAA, it would appear that some as-yet unidentified person of unknown title, qualifications and experience (at least to those outside the FAA) "jumped the gun" in apparent overreaction to a single Ercoupe accident. Yes, that's definitely getting the "cart before the horse" when there is, as of yet, been no NTSB "finding" as to said "root cause".

This may be (we don't know) because of heightened sensitivity to possible public reaction to the fact that as the undeniable structural failure and subsequent airframe disintegration sequentially took place both occupants were forcibly ejected, almost certainly against their will and while
properly belted in.

It should be obvious to all but the most obtuse that such sudden and massive negative G forces as would eject both belted-in occupants and break the main spar resulted from aerodynamic stress well beyond design requirements of CAR 04. The almost identical failure and disintegration of the 415-E with the "Trim-o-matic" that Bob Sanders lived through should have been thoroughly investigated by appropriate agencies. Those records should be available under a "Freedom of
Information" Request.

I shall be making such a request so that these records, and others, will be available should the FAA decide to proceed with a premature AD on the obviously incorrect and unsupportable premise that holes as yet not specifically identified and alleged to be resulting from "unauthorized maintenance" were somehow the "root cause" of such sudden and massive negative G failure as occurred. In my opinion that scenario is so unlikely as to be utterly and totally preposterous.

I believe all aircraft owners have the obligation to one another to stand together to assure that the NTSB and FAA act only in full accordance with their respective "mission" to protect the public from reasonably real or perceived threats. It appears likely that never before has an AD been issued on:

a. the basis of a single accident prior to an official finding as to "root cause" of same, and

b. alleging such wide ranging "probable cause" as "unauthorized maintenance/holes".

Such unreasonableness, if allowed, will eventually and predictably result in such progressive regulatory and financial harassment without "probable cause" as to eventually and utterly destroy private aviation in the United States. That is why I am so motivated to have this sort of unjustifiable nonsense stopped RIGHT HERE AND NOW...stomp hard on the camel's nose when it is first pushed under the edge of the tent and you avoid the considerably greater necessity of ejecting the whole
camel once fully in the tent (and maybe mad).

I would remind one and all that Univair, as holder of numerous Type Certificates and utterly dependent upon the FAA for continuing approvals necessary to the day-to-day conduct of their business, is extremely constrained when it comes to opposing anything the FAA decides it wants to do. The EOC, if their individual or collective analysis and response is inadequate, could give the FAA all it needs to disregard
the more thorough and aggressive arguments of individual owners.

Yes, good people, here there be dragons. Who will step forward and file comments to help slay them?

Regards,

William R. Bayne

 I'm kind of confused at what's going on!
 It all doesn't seem to make too much sense.
Are we looking into why the Ercoupe had an inflight brake up at Sebring, FL- or are we trying to find a fault with the spar without any justifiable proof.
 if indeed it was the spar that caused that crash.
 Will somebody please set me straight or am I missing something?
 Thank you,
 Prof. Ed
