I find Jeff's comments offensive at so many levels that I am having difficulty sorting my thoughts.

In a world FULL of nattering bureaucrats who cloak their perpetual avarice quest for dominion over the plurality in a veil of mock concern for the public good, one can taken refuge in the reasoned sanity of self responsibility afforded by the Experimental Aircraft category. To have one of our own betray that sanity with a call borne from self proclaimed ignorance is the pinnacle of demagoguery. The grave risk is that others, who have forsaken reasoned thought, are quick to rally to the standard of "We do this for your own safety".

What I find particularly repugnant is that this misinformed implied attribution of fault to the design is counterproductive to the true mitigation of risk. The fundamental design is valid as demonstrated both analytically and empirically. Claiming intrinsic fault in the design at this point is equivalent to claiming that obesity is the product of cutlery. Tabloid headline "400 pound woman cries "Spoons made me fat!""

The reason that the NTSB starts with the assumption that all accidents are the fault of the pilot is that if they simply applied a "Pilot Error" rubber stamp after “Cause:” on ALL accident reports they would be right 90% of the time.  I am unaware of ANY accident involving a Lancair that was the result of a design induced failure.

Perspicacity is not requisite as a simple review of Part 91 accidents shows they are precipitated predominantly (~90%) by three classes of pilot error; fuel starvation, stall / spin and VFR pilot in IMC. The balance, ~10%, is a mix of other causes including mechanical failure. In the Experimental Category we have the additional, and significant added factor of "Builder Error".  If "Builder Error" induced accidents are removed from the database it is likely that the accident causality distribution will closely match that in the Part 91 general case.

Builder Error is induced in several ways, including:

1) The builder does not comply with the assembly instructions and good workmanship practices. Examples include the builder failing to remove peal ply, substituting materials, failing to vent internal cavities, failure to keep fuel tanks free of contamination. etc. etc.

2) The builder deviates from the design without proper analysis. The experimental builder is predisposed to "do things differently" and will deviate from a demonstrated working solution in an effort to "Improve" the design. Sometimes this is a good thing and sometimes not. The engineering wisdom needed to evaluate the suitability of a design change is not miraculously bestowed on a builder when they write the kit deposit check. Many builders, while capable of following directions, completely lack the requisite analytical skills to the extent that they do not even realize that what they are contemplating may have fatal consequences. One builder decided that the aileron pushrods located in the wings would work better if they were used in torsion rather in tension / compression. When I asked if they had analyzed the effect the torsional modulus would have on flutter they responded with a blank stare that haunts me to this day.

3) Builders that fail to properly maintain their aircraft. You KNOW you could do better, don't you?

The FAA recognizes, and correctly so, that every Experimental aircraft has a unique manufacturer, the builder. Therefore, every experimental aircraft, while they may share similarities with others, are recognized as unique and a member of a fleet of one.  This fact precludes "grounding the whole fleet" as both a legal and functional impracticality.

Lancairs' high performance places them outside the realm of "certifiable" and therefore, arguably, they are not as safe as a Piper Cub, a plane that can just barely kill you. This performance is WHY we want them. This was not some hidden fact sprung on the unsuspecting builder during flight testing.  You were fully informed, if not seduced by the promise of speed and grace. Do not NOW have the audacity and intellectual dishonesty to propose that this performance constitutes a design flaw. Better one should relocate next to an aerodrome and shake their raised fist in anger at the noise. At least then one would have the camaraderie of like minded miscreants who have abandoned self responsibility and critical thinking.

Lancair is not responsible for the safety of an aircraft you build any more than a chicken is responsible if your soufflé fails to rise. As pilots and builders it is essential that we shoulder the responsibility for our own safety and the actions that affect same.  Those that look to others to ensure their aeronautical safety will at best be disappointed or at worst be making an appointment for a dirt nap.

The litigious elements in our society offer monetary rewards for those who adopt the premise that personal responsibility can be assigned to others.  The siren song of a jury punitive award is irresistible to most. This attitude is an artifice that is infiltrating citizens' perception of the nature of responsibility. Efforts spent on a misguided call for others into action result in the perception that all is being done to remediate the situation. Would you stand beneath the falling piano pontificating on the need for higher Block and Tackle Safety Standards?

We have met the enemy and they is us. Point the finger at the factory, it is the builder, it is you, and DO something about it. Inspect YOUR airplane. Maintain YOUR airplane. Practice YOUR skills and emergency procedures. Keep current in YOUR airplane.

Builder Pilots who look to others as responsible for their safety and their actions are, indeed, unsafe in ANY plane.
