I believe that what you state about the added safety factor of the retract
is absolutely true, but of all the small aircraft that are manufactured with
retracts, I'll bet that none of them have retracts just to make them more
safe.

When I converted my first KR to fixed gear, then the "Rand" fixed aluminum
spring bar, I was concerned about the small bolts that attach it to the
aluminum brackets.  A friend speculated that there was a reason for that,
and that it was probably so that in the event of an off field landing, the
gear would snap off.  195 hours of landing on pavement and grass and it
never failed.

I might be crazy, but I built my plane for flying, not for ditching.   I
think the BRS would be a better solution for that, anyway.

See you at the 2009 - KR Gathering in Mt. Vernon, Ill
There is a time for building and a time for FLYING and the time for Flying
has begun.

Subject: RE: KR> Tri Gear Conversion

Netters,

Not too long ago a kr-2 went down here in Washington.  I understood it
to be a fatality event.  There were pics on the internet and a short
video of an automobile tow truck trying to right the plane, which was
tri-gear equipped and after landing in a (soft) field flipped over, I am
guessing over the nose gear and prop.

Probably the resulting flopping down on the head, upside down would
account for the fatality.. but that is a guess.  There was no fire.

I have seen videos of tailwheel and tri gear aircraft landing in water.
Always with devastating results.

It seems to me that the same aircraft landing in mud or a very soft
field would give similar results.  The gear grab ahold of the water or
mud, and provide unsafe deceleration.

After watching and reading this group for more than a year or two I have
not seen this discussed.

What of the safety provided by retracts in super soft field (mud) and
water landings?  At the last gathering, I met john Shafer who had put
his kr down in a corn field gear up (his was the only flying example of
trigear full retracts on a kr2)..

He described sliding along the mud, corn stalks, and snow  (with gear
up) as a non-event compared to having to do the same thing in a fixed
trike or tailwheel plane.

I know  alot of guys have the original retracts, and alot of guys shun
them.  But isin't being able to clean up the undercarriage (during a
forced landing) a HUGE plus?  especially for super soft field (mud) or
water landings?

All my forced landing here in western Washington are probably going to
be within reach of water..  I think it's worth keeping retracts for, or
making a tricycle set of retracts for...

Any opinions to chime in here??  ANyone here put down in water with
fixed gear? How did that work out?
