ACCIDENTS AND INCIDENTS
REQUIEM? FOR A LONG-EZ
With much excitement, I awoke on the morning of June 14, 1986,
The previous night, I had been up late - washing and waxing my LongEZ, N23RY. I wanted her
to look her very best while on display at the big Texas Sesquicentennial Airshow in Waco,
Texas. With my wife, Margi. settled in the back, we enjoyed a comfortable 45 minute flight
from our home base at the Addison Airport in North Dallas.
It grew to be an oppressively hot day - right at I 00 degrees. We
enjoyed a great airshow, yet after having answered hundreds of spectator questions, we
were anxious to get airborne once the field reopened. A little over half way back to
Dallas at approximately 2500 feet AGL, we experienced a sudden complete loss of power.
Searching around, I spotted a field about a mile off the right wing. As I swung into a
wide right-hand turn to land into the wind, I turned on the boost pump, switched fuel
tanks and checked the mixture and mags all to no avail. Established on a base leg, I can
recall observing a line of trees at the roll-out end of the field and utility lines at the
approach end. Given what I estimated to be about 2,500 feet of field in between, I decided
that my approach path should be planned to just clear the wires. I felt well prepared for
this situation since I had performed a good number of practice forced landings and actual
engine shut-downs both during my thorough flight test phase and subsequently. My 170 hours
in this Long-EZ had been accumulated since her maiden flight four months previously. My
overall experience includes 9,300 logged hours as a professional pilot in a wide variety
of aircraft.
Once on final, Margi recalled me saying that I needed to go a
little bit lower. I remember feeling confident on a short final that everything was going
to turn out OK. Tragically, this was not the case as I was to realize while slowly
emerging from heavy morphine sedation a week or so later.
I was disappointed with the FAA's investigation of the accident.
Once the badly damaged forward fuel lines were by-passed and the prop replaced, the engine
started up and ran satisfactorily. Despite the extensive damage at the fuel selector
location, the FAA said the AN 818 aluminum coupling nuts were found to be finger tight and
listed this as the probable cause. This was hard for me to accept as I had recently
applied fuel tube to help unstick the fuel selector valve and had checked that these
fittings were plenty snug. I personally suspect that given the hot conditions and my use
of mogas that the occurrence of vapor lock was a possibility.
The accident investigation revealed that after impact with some
smaller gage wires near the top of the cluster, the aircraft impacted the ground 70
degrees nose down at approximately 70 kts wings level. The fuselage shattered with severe
damage extending to and including the front seat bulkhead. I was ejected at the impact
point as the aircraft flipped over and came to rest 27 feet further on. Margi was
terrified as she remained secured in the inverted aircraft with fuel coming out of the
broken vent lines. Other damage included: a clean shearing off of the right winglet at the
attach juncture, one-third of the top left winglet crushed (with no apparent damage at the
juncture), the left-hand baggage pod sheared off in the wing saddle area although the
right-hand pod remained attached intact, the canopy and aft turtle-deck were flattened to
within approximately 4 inches of the longerons, the head rest sheared off along with a
good portion of the front seat bulkhead, the canard remained surprisingly intact except
for major crushing damage to the center section area.
We thank God that given the severity of the forward fuselage and
canopy damage, that both Margi and myself came out of it alive and reasonably well. She
suffered a concussion and a cracked rib. We were very fortunate that bystanders were
immediately available to re-right the aircraft and extricate Margi. Also, a veterinarian
was right on hand and administered three tourniquets to me. A Care-Flight helicopter
delivered me to the emergency room in quick order. I dont know how, but I appeared
to have maintained consciousness during the whole ordeal. Unfortunately, both my legs were
eventually amputated just above the knees. I am thoroughly convinced that my decision to
employ approximately 15 pounds of extra thickness thermo-foam absorbed a great deal of the
impact forces and prevented both of us from receiving any internal or spinal injuries. In
reflecting on how this tragedy might have been avoided, I would advise against the use of
any automotive fuel. Although I had no problems in using it up to that day, operating
temperatures had never exceeded about 80 degrees. In all honesty, I cannot rule out that
human factors may have played a part. The long hot day standing on the concrete ramp left
me feeling irritable and not too perky. It is possible that my judgment could have been
impaired.
The point at which my landing gear snagged the thin wires
indicated that just another two feet of attitude would probably have put me in the clear.
In evaluating the position of the canard relative to a line extending from my eye level to
the aircraft flight path it appears to be within the realm of possibilities that the
highest thin gage wire that I struck could have been hidden from my view by the canard.
With this in mind, I would caution anyone flying a canard aircraft to closely eyeball the
approach area well prior to getting set up on final approach.
Besides being concerned with the utility lines at the approach
end, I was equally preoccupied with the consequences of not stopping before reaching the
trees at the end of the field. I suppose its a natural feeling for a pilot - especially a
homebuilder to avoid anything that could inflict even the slightest damage to his
creation. Had I been willing to just get it down and accept the possibility of minor
airframe damage, I could have avoided all personal injury.
No other aircraft has ever come close to providing me with the
great satisfaction and sheer flying excitement as N23RY did. Given the nature of my
disability (specifically-, loss of ankle articulation), the rudder,/brake combination of
an unmodified Long-EZ represents a viable and realistic opportunity for me to get back
flying again. I am contemplating a static load analysis of my aircraft which has been
stored in my garage.
Amazingly,,, close visual inspection of the wings, spar, strakes
and rear half of the fuselage reveals no apparent damage. Any builder/flyer of a properly
constructed Long-EZ is entitled to utmost confidence in its structural integrity, energy
absorbent characteristics and resultant crash worthiness.
My twin brother, Al, and his wife, Cathi, are heading towards completion of their beautiful Cozy later on this year. I'm really excited and will not hesitate to go up and fly that Rutan derivative.
