By asking for optimal pressure drops, Jabiru is protecting itself against warranty
claims related to overheating.>>?

Hi All,?
this is my first posting to this list and it is obvious from lurking that you guys
are much more technically knowledgeable than I. On a scale of 1 to 10 put
me in as zero.?
I fly a Kolb Extra with a Jabiru pusher, in the UK. I have had little experience
as I managed to start the engine with the throttle wide open after only a few
hours flying . I hit a barn, and a parked car. The rebuild has just been completed
and I am waiting for Permission to Test Fly at the moment.?
?
I queried the rumours of Jabi`s overheating with the dealer when I ordered the
plane and he assured me that it was a thing of the past and more up to date engines
were OK. My engine must now be around 2 years old. Any comments??
?
Cheers?
?
Pat ?

Pat, how big was the barn ?>>
Big enough to see but too big to avoid.
I fell victim to the Jabi policy of the throttle going to full throttle
in case of failure. I had been flying a Challenger with Rotax 503 for
many years with no need to adjust the throttle friction.
In the Kolb there is a friction adjustment under the pilots seat and I
obviously had not tightened it quite enough. The choke is high behind my
right shoulder. In my left hip trouser pocket I had my credit card case.
In starting I needed to set or reset the choke several times and each
time I twisted in my seat the wallet nudged the throttle open. The Jabi
propensity to go to open throttle did the rest.
The engine fired and she went like a bat out of hell across the farm
yard. My wife who had helped me rig, and thank heaven was standing
behind the wing swears that I took off , in 30 yards, before impacting
an RSJ (I beam) supporting the corner of the barn about halfway along
the port wing.
I had intended only to taxi onto the field to fuel up, a matter of a
hundred yards, and had strapped in only as a reflex action. Very lucky
as otherwise I would have gone from being pushed back in the seat by the
acceleration to a 150 degree swing and sudden deceleration as I hit the
parked car, which would certainly have thrown me around the cockpit,
(its a side by side 2 seater) with resulting injury.
Thank goodness the engine was high and behind the wing and the prop hit
nothing. If it had been a tractor set up it would have meant new prop
and probable shock loading of the engine to deal with.
Cheers
Pat

Andy believes that Jabiru's warranty starts from first run. Unfortunately, my warranty
is ambiguous on this point. My warranty states:
*15 JABIRU AIRCRAFT PTY LTD -- NEW ENGINE WARRANTY*
Jabiru Aircraft Pty Ltd, hereinafter JABIRU warrants that it will make
good without charge,
any defect which appears in this engine.
Provided:
5 The defect has been notified in writing to JABIRU:
i) before the engine has operated a total of 200 hours or,
ii) within twelve (12) months of the date of delivery of the engine to
the first
retail purchaser or from the date of independent Authority authenticated
first
flight.
Whichever comes first, and ...
Does ii) "within twelve (12) months of the date of delivery," rule, or does, "from
the date of independent Authority authenticated first flight," rule? And,
what constitutes an "independent Authority?"
Since I bought my engine w/o thinking about possible warranty expiration, I really
hope Andy is correct that the warranty does not start until my first flight.
However, I fear that my warranty will be expired before I ever bolt it onto
the aircraft. Since my engine came from Jabiru USA, perhaps Pete can shed some
light on this.

Pete,
Amazing it was the Yellow Wire! I put a 30 amp fuse in line and it must have gotten
some moisture in it and the fuse blew/cooked in the supposed weather proof
boot it came with. The stators and the copper wiring were shiny and when we
fired the engine up my readings on the voltmeters went up to 14.3 volts.
Thanks,
Jeff
