ACCIDENTS
From CP49, Page 4 (July, 1986)
A Long-EZ in Illinois
landed in a row of trees after the engine quit. The pilot was on a 112 mile final at 300
feet at idle power due to another plane in front of him. When he added power, the engine
quit. Two attempts were made to start the engine using the electric starter, to no avail .
He hit a small electric wire, then landed in a row of trees planted as a wind break. The
canard broke on both sides, the right wing broke at 1/2 span, the left wing was damaged
near the strake. The main gear was still attached but bent aft. The left wheel/axle was
sheared off breaking all four bolts. The pilot received a small cut on his hand and that
was all. No cause for the engine quitting has been determined. The first thing that comes
to mind, of course, is the engine idle speed. This may or may not have had anything to do
with this accident, but we have seen airplanes set up with such low idle speeds that they
do have a tendency to quit on short final. However, that is normally an occurrence in the
flare where it is only an annoyance as far as taxiing after the landing. An excessively
high idle RPM is not satisfactory in that it makes it tough to land an airplane with the
L/D of a Long-EZ. In general, if your engine will idle OK on the ground, it will idle-even
easier at approach due to inflow assisting the propeller.
These values are probably incorrect as a Long-EZ can easily glide
1/2 mile from 300 feet while decelerating 10 knots.

A Northern Nevada VariViggen was involved in a first flight,
take-off accident. The airplane was demolished but the pilot suffered only minor cuts and
bruises. Unfortunately, this accident could easily have been avoided. The pilot had no
current medical or biennial, nor had he flown at all in the past 3 years. He did not
inform the FAA of his intention to fly and he attempted to take-off on an uphill runway
with a tail wind.
------------------------------------------------------
A California VariEze crashed on final approach. The pilot was
seriously injured and the airplane was badly damaged. His approach was at a busy fly-in
with a lot of airplanes on final. He got down too low and far too slow. Eyewitnesses saw
the airplane very low with wing rock. The airplane caught a wing on the approach light
system, 800 feet short of the runway and 15 feet above the ground. The airplane
cart-wheeled and hit upside down and slid to a stop 300 feet short of the runway. The
moral here is "never be too proud to execute a go-around, no matter how much pressure
there is to land."
------------------------------------------------------
A Long-EZ on its first flight after installing a newly overhauled
engine suffered an in-flight engine fire and was unable to make it back to the runway. The
engine quit on approach and the pilot attempted to land in a housing tract. There was not
enough room and he rolled into a car, which also burst into flames. He landed under
control, thus, in-flight structural failure or control failure are not suspect. Sadly, the
pilot was killed by fire. The fire was so intense in the engine/cowling area that the FAA
accident investigator was unable to determine what could have started the fire. The fuel
pumps, carburetor, etc., were consumed. The airplane had been airborne for only a few
minutes. Reportedly, the engine was an 0-320 and he was using auto fuel. We may never know
what caused the fire, but it is easy to overlook a loose fitting - we have done it
ourselves. A fuel leak, particularly auto fuel, could be ignited by hot exhaust or any
number of things. Always try to have at least one other person go over your work,
especially engine related work like plumbing or control systems. The more pairs of eyes
that look at your engine installation, the better chance that you will catch some
overlooked items. This is specifically important if you are developing new, unapproved
installations.
Never, ever, cowl an engine that has been worked on without a
brief engine run to check for leaks. We, here at RAF, have more than once found fairly
drastic leaks during the leak-check engine run.
