KR> Broke My Plane, a little Mixture setting

[Nerobro]

I have always wondered why lycoming and continental have steadfastly stuck
to ancient carb (and fuel injection) tech.   ...  i think rotax is running
cv carbs on the 912 which is nice.

I love my Ellison and would not trade it for any carb, period.  No, Not, Never.

One advantage to having a carb with an accelerator pump instead of the throttle 
body injector carbs.  Just pointing it out, not trying

I Just love this image


I have talked to Mark about this and it makes me feel just great !!!
with my primal attempts EE Haa. Just get on with it
Life is t short. Now days Mark could win a spot landing contest.
Prop stopped out of air out of energyHe learned well...

KR> Broke My Plane, a little

[Dan Heath]

Before pancake breakfast at the SAC ( Sport Aviation Center ) I went out for
"Dawn" patrol and a few "touch-and-gos".  After 1 very nice approach and 1
very good touch and go, I decided that it was time to land for pancakes.  I
thought I had the landing set up perfectly and was just holding attitude for
the KR to settle on to the runway.  I must have mis-judged my airspeed, kind
of hard to watch it when in landing mode, and the bottom dropped out enough
to cause a bounce.  So, I lowered the nose thinking again that I had it made
and the bottom dropped out for the second bounce.  2 bounces are my limit,
so I quickly applied power for a go-around and . silence..



Visions of others having reported "porpoising" crashes started flashing
before my eyes.  NO..., if I go in, I go in flying and pushed the stick
forward, only to continue the cycle of bounce, nose high, push forward, till
finally the KR stayed on the runway only to take off to the left and end up
in the grass.  Sliding all over the place, I see a runway light in my path,
so applied as much right rudder and brake as I could, to get back on the
runway.



I finally came to a full stop, can't remember if I had made the runway or
was still in the grass.  So I tried to start the engine and it came to life
immediately.  I proceeded to taxi back to the hangar, flipped the speed
brake switch up, and the brake did not come up.  I am now having visions of
a large hole in the bottom of my fuselage due to whatever had damaged the
speed brake servo, and possibly severe damage to the gear and possibly the
spar due to slamming it so many times on the runway.



So, I pushed the plane into the hangar and went into the SAC to eat
pancakes.



After pancakes, I reluctantly went back to the hangar to access the damage.
The underside of the fuselage appeared to be intact and after a quick
inspection of the gear, it seemed that I had only damaged the wheel pants,
AGAIN!  I took the back of the seat out and found that the control module
for the speed brake servo had popped out of the socket and was laying on the
floor.  I replaced it, and the servo worked perfectly.



Now I carefully inspected the gear and see that there was a large cracking
of the upper fairing.  And looking on the top of the wing, there was a bit
of a bump just above where the gear bracket is attached.  So I was very
concerned that there might be damage to the spar and had to find out before
I fly again.  I cut a hole in the wing, in the front and back of the spar to
get a good look inside.  So far, I see no damage to the spar, but will look
much closer tomorrow.



I'll bet you are wondering why this really great Corvair engine that I have,
quit on me like that.  It was nothing but pilot error.  I always run the
engine as lean as possible due to the high lead content of 100LL, which I
always use, and when approaching landing,  I always push it a little more
rich.  Well, I did not push it enough rich and when I quickly applied power,
the engine could not run with so little fuel for all that air and stopped
suddenly.



You know the moral of this story, but I will repeat it for anyone who may be
tempted to do what I did, or rather, did not do.  On approach to landing, be
sure that your mixture control is on its optimum rich setting.  I promise to
always put my fuel selector on the most full tank ( a lesson learned from a
previous adventure) and to push my mixture to the most rich position when
approaching a landing.  I promise.



This KR is one tough bird!!!

Glad you didn't do any serious damage.  After watching that spar breaking 
test at the Gathering a few years ago, I doubt you hurt the spar at all.

I learned some similar wisdom on my first flight in N56ML.  I was about to 
"drop it in" from about 6 feet up, and stuffed the throttle from idle to 
wide open in about a nanosecond.  The prop quit instantly, and I dropped it 
in anyway, putting 5.5 g's on the g-meter!  See the bottom photo at 
http://www.n56ml.com/flights/second/ for the actual drop-in.  Needless to 
say, I learned from that to be a lot more gentle when opening the throttle.

There are several other lessons learned detailed on that page too.  On 
another incident, I managed to tear a wheel pant off landing short at M38, 
which also ripped the gear leg fairing at the wing.  No spar problem there 
either.  Hopefully your bump is only a chunk of foam or something...
