Hi Bernardo,
Thanks for your comments on the newsletter. Your feedback on articles
and items in the newsletter help me know what is really helpful and thus
important to Lightning builders and flyers.
As to the FAA accident case study about the Jabiru engine failure due
to rust in the Bing carb, I hope everyone that reads the newsletter will
take the time to follow the link to the FAA write up on this fatal accident.
Although I suspect that if a Jabiru engine is only fed a diet of aviation
fuel (or certainly no ethanol in any auto fuel) and if that engine is run
regularly, there probably would be no problem like this article describes.
But information like presented in this article is knowledge, and I am a
firm believer of knowing as must as possible about the "equipment" we fly.
Good luck on your Lightning build. Keep the "Newsletter staff"
informed of your progress so we can have good things to write about.
Blue Skies,
Buz

Hi Buz,
Nice newsletter! I was pleasantly surprised to see my emails to you along
with the pictures of my little Corby Starlet, "Estrellita". Thank you.
I read with interest your June 2010 newsletter link to "Accident Case
Study, A Fatal Case of a Little Corrosion in the Worst Place".
I think that not only should this be required reading for all those with
Bing carburetors on their aircraft engines, but that it should be an annual
inspection item, to assess if all is smooth and shiny inside the
carburetor, with no binding. Hard to imagine a little rust can be fatal as it
was in
this case. I know that I will check mine annually, at least, or more often.
Of course, my preference would be to have fuel injection on my engine for
better fuel distribution, no carburetor icing issues and better fuel
economy. Is that available? I've experienced carburetor icing before and I was
not a happy camper. It really grabs your attention! We don't want the
cooling fan to stop in mid air because if it stops, you start sweating. Remember,
air is soft, ground is hard. "Mis dos centavos" ($.02).
Regards,
Bernardo Melendez

The only problem with the story in the FAA newsletter about corrosion in the
carb is that it was not the corrosion in the carb that caused the engine
stoppage. In addition to the corrosion there was a sticky substance in the
carb that held the piston open in spite of gravity and the spring trying to
close it. When he applied full power for take off the piston was pulled up
into the dome. Then when power was reduced for cruise the piston stuck up
in the dome holding the jet needle up and allowing a lot of fuel to flow
through the jet while the throttle butterfly closed a bit and reduced
airflow through the carb. The resulting over rich condition caused the
engine to eventually stop. The sticky substance may have come from a
substance used to repair a leak in the fuel tank.
While the corrosion in that carb may have lead to an early carb rebuild I
don't think it was much of a factor in this accident. If the author of the
article had waited for additional results of the NTSB investigation he may
have reached a different conclusion or the article may have been better
titled "Foreign Substance in Fuel System"

Hello Pete,
=0AThanks for your input. I had not thought it through about the "sticky"
=0Asubstance, but in retrospect, it makes sense.
That's what I like about this group, always on top of things. Like a chicke
n on a June bug.
Best regards,
