AD NSI CAP Prop

[Ghost]

This summer an RAA member suffered the loss of a prop blade on his =
amphibious 912S Kitfox, that was equipped with a NSI CAP 140 =
propeller.The engine immediately broke from its mount, but fortunately =
was retained by the hoses and cables. The pilot was able to make a =
successful emergency landing with the departed blade stuck into his =
float.

The NSI CAP 140 prop is in-flight adjustable and has three Warp Drive =
blades that are modified by the addition of an aluminum cuff that fits =
into the NSI hub. There have so far been two versions of this cuff, with =
a third version about to be released. Some applications will have their =
effective lives limited by this AD, and others are grounded immediately. =
New version 3 parts are not yet ready, so some planes will be grounded =
until parts are available near the end of this year.

Effective immediately, all 912S Rotax engines with either the version =
1 or version 2 cuff are grounded. These parts may not be used any =
longer. Ship your blades to NSI for installation of the version 3 cuff. =
Lance Wheeler has told me this morning that the cost will be under $500 =
US.

Effective immediately, all 912 engines with the version 1 cuff are =
limited to 500 hours. All 912 engines with the version 2 cuff are =
limited to 1000 hours. Blades must then be shipped to NSI for =
installation of the version 3 cuff.

Effective immediately, all 914 engines with the version 1 cuff are =
limited to 700 hours. All 914 engines with the version 2 cuff are =
limited to 1000 hours. Blades must then be shipped to NSI for =
installation of the version 3 cuff.

In Lance Wheeler's estimate, blades fitted with the version 3 cuff =
will have an effective life of 2000 hours.This estimate has been =
calculated by Finite Element Analysis. The full story on this will be =
printed in the next issue of the Recreational Flyer.

Although I have no dog in this fight, it would be a cold day in He**, before
I would pay $500 for the "privilege" to do some more "flight testing" of
this product.

So.. how much would you pay for the priveledge of flight testing a Lyc
or Continental crankshaft after the most recent recall on those products?

Not very well. If a manufacturer screws up, it ought to foot the bill for
all costs incurred.

I'm not flying at present because of some medical issues, but once I get
that squared away, plus the finances recovered from said problems, I would
much rather test fly my *own* homebrew power plant. <g>

Can I interest you in the Mazda Rotary line of power? Very few
catastrophic failure modes...

CORVAIR or Volkswagen derivative?

I *knew* this would bring you back from the dead. <g> Simply too much to
resist!

Nothing air-cooled, thank you. I'm thinking water cooled, and smaller, to
fit in the sport pilot class. A Chevy 4.3 would be great, but I would have
to make an airframe that weighed about 57 pounds. <g> Not likely.

Motorcycle engine? Soob? I don't know. I've got a while to think about
it.

I don't know...when I finished welding my MoHawk fuselage (Kitfox clone) I
weighed it, and it weighed (oddly enough) 57#.

You just can't add wings...or fabric...or landing gear... or paint, ...or...

Don't get me wrong: I love the Mazda (more properly "Wankel"), too. But the
single most common causes of engine failure apply to it as well: fuel
problems. And because every Wankel installation is a unique experimental
installation, it is perhaps more at risk of problems than your
run-of-the-mill Lycoming installation.

As best as I see it, there's only one certain way to avoid engine or prop
failure: fly a glider!

Yep, that's strange.

Thing is, I like skin....and landing gear... and wings...and all that other
*stuff*.

You're a glutton for punishment.
Go Soob and a 60 lb airframe.

Fly a GLIDER?!?!?!?!?

Surely, you jest.

It has amazed me how many power pilots
would not give our sailplane club ships a try.
Every excuse in the book has been used to beg off.

IMO, many power jockeys secretly fear embarrassment or worse,
when no engine is available to mask possible shortcomings of
basic skills and judgment required for true mastery of flight.

Now Uncle Bob, I have flown a glider a couple of times and lived to
tell about it. Of coure it was not by choice, it was when the fan up
front quit turning on its own. I was not embarrassed at all when I
walked away from them. :-)

Please contain yourself.
No need to get carried away, Jim.

The approval is a limited endorsement for
YOU - and wannabee d5 Yawn Jimenez.

You're no photographer but...
surely, you get the picture. <g>

THAT was below the belt. Me and YAWN in the same line?

I'm reminded of the old gem: "How does one acquire good judgment? By making
bad decisions."

Great sound bite, and repeatable...
for Tiddlywinks or MS Flight Simulator.

In the real flying world, surviving multiple
bad flight decisions is nearly impossible.

JFK Jr. is but one tragic example.

Someone said that we each start our flying careers with a full glass of luck
and an empty glass of skill. The idea is to fill the skill glass before the
luck glass is empty!

I mostly agree- I think the idea is to not empty the luck glass too
quickly (or at all), at least not empty it faster than the other one
fills :)

Or let's be less philisophical- don't do dumb stuff!
