Background: Jabiru 2200 Bing carburetor was fully serviced for the first time in 14 years by Rotax dealer; also who was my flight instructor who taught me how to fly.

Since the carburetor was off, I decided to route new fuel lines since I did not have a bypass line with a one-way check valve. I also replaced my fuel pump with a brand new fuel pump with a built-in check valve.

Yesterday, I put fresh fuel in and started up the motor for about 10 or 12 minutes and then did a static run test. I went full power for about 10 seconds and then slam their throttle right down to idle to see if it would stall. It did not install. I did this multiple times on the ground.

Today, I fired up the engine and warmed it up as usual and then did a static run before my first flight of the year. I was flying with a pilot that has 48 years of flying experience in over 30 aircraft.

The takeoff went great but then the master breaker popped as well as my 3 amp transponder breaker also popping. I don't know why this happened as it never happened before but I pushed back in the master breaker and we continue flying without any issues.

As we were approaching to land my airplane everything was going well. I was coming in a little too fast so as soon as I was over the runway I moved the throttle right back to idle position at which point I flared too early and the airplane ballooned a little bit but nothing crazy. When a lightly kissed the ground and the nose went up the engine all of a sudden installed and the propeller stopped turning. Luckily at that point I was able to land without any hard effects but both of us were extremely shocked the engine stalled. Thank goodness it was literally right at the end. It easily fired back up and then I did another static run and slammed it back to idle and it did not stop.

I am scratching my head as to why it's stalled. It has never ever done this before. I forgot to use electric boost pump when I was landing which may have helped the issue not even happen? Perhaps it was an air bubble or air pocket that was trapped in the brand new fuel line?

I do not have any fuel leaks right now or smell any fuel and all my brand new lines are bone dry.

I think it is coincidental that the master breaker and the transponder breaker popping has nothing to do with the engine stopping. But that has never happened to me either.

yesterday I noticed my engine idling at about 12:00 or 1300 RPM so this morning I took out my 7 mm wrench to try and lower the idle stop screw at which point it did and now it idles at about 1,000 RPM.

Any guidance as to the culprits of the engine stopping is greatly appreciated as I intend to fly in 2 days from now and do not want this to happen again. Thank you

Carb ice??

I was flying 1000AGL, 17 celsius, 8knot wind from the east. Not exactly sure what the humidity was.

I have electronic carb heat but that was not on at any point throughout the flight.

My only concern is “slamming” the throttle …..

It is ok to aggressively pull the throttle back to idle when recovering from , for example, a spiral dive, ?but I would never “slam “ it back. ??
No idea if that gad any bearing on your problem.?

At other times throttle should be advanced or retarded more gradually …..

taking x air out of (long-term) storage / de winterizing / getting ready to fly

 

i plan to start up my x air today after being in storage for about 4 months.

I sprayed fogging oil into the top valve covers as well as in each cylinder.?

How necessary is it to remove all plugs, turn engine over several times with electric starter and then put all plugs back and fire it up?

I really dont want to take cowling on and off multiple times and have fogging oil spray all over my windshield and engine, etc...

I wonder if it will fire up, knowing i have dual ignition, in the event one plug in each jug doesnt fire from fogging residue. I will be putting new plugs in anyway.

What do you all think? How do you guys de-'winterize' your planes from 'long-term' storage?

Hi Justin,

Not to take anything away from the contributors here, but on the same groups.io form as this one, there is a Jabiru & Camit engine forum (jabcamit) with lots of guys and gals who know loads about these engines. ?Just like here, they’re a friendly and helpful bunch.

Just in case you’d missed the Jabiru forum, I thought it might help.

good to know Sir!

...If this X Air Hawk/Hanuman wasn't fabric covered, I'd replace with a 100HP Rotax and put amphibious floats and keep it for life!

Overall, it truly is a fantastic aircraft.

It will decrease in pressure because of the increased head and also friction losses in the tubing (I did a semester studying fluid dynamics as a surveyor many years ago trying to get water to go up hill)

The only way to verify is to put a fuel pressure gauge right at the carburettor entry.

do you guys think technically - if the fuel pump is about 40 inches before the carburetor, the PSI output pressure will decrease slightly from 4.5 to about 4.25, for example?

ok perfect - so my current 3-4.5 psi set up works - great to know.

I'll just replace the current pump with the exact make and model, or if there are stock shortages near my location, ill find something with a max of 4.5psi

Hello again Gents,

I cannot find any information regarding the GPH (gallons per hour) or PSI min. & max. for our electric fuel pumps.???? this will be in the requirements from the engine manufacturer, it will stipulate a minimum and a maximum psi for the fuel supply so this is nothing to do with the aircraft but is unique to individual engines

After a frustrating 20 minutes, I was able to remove the fiberglass belly pan of the X Air H. I am glad I did this because the previous owner didnt install the bypass fuel line section with a 1-way check valve! Why do you think he did not do this? ignorance or trying to keep costs as low as possible??? He built the airplane pretty well with upgraded wiring and other parts, but maybe because he felt more connections means greater potential for leaks?????

Moreover, I notice I have a Facet Cube fuel pump - model # 40105. The specs on the Cube 40105 are: 30GPH, 3.0 min PSI and 4.5 max PSI.????? a quick Google search led me to the Jabiru manufacturers website where it states the maximum pressure should be 3 psi please this is just a Google search please look at the manufacturers manual and specifications for their product

Is this correct? I feel like I should replace the electric pump, just in case. Here is my reasoning: the previous owner didnt even install the supplied Facet fuel filter into the Facet Cube! Why did he not do this as well????? because of the well-known problems with clogging of this filter. Most people do not use this filter and instead install a proper filter upstream

After the fuel tank, I do have a Dorman 55240 glass fuel filter, which is great, but because of my paranoia with the fiberglass/resin and organic particles in my 100LL fuel that is currently in the tank, I wont be surprised if there are some fine particles trapped within my Facet Cube - engine & plane currently at 160hours.?

I cant seem to find any info regarding how much min. and max. and GPH my 22A2895 Jabiru 2200 (160hrs) calls for, in the event my Jabiru mechanical fuel pump fails.

It is pretty simple I just went to the Jabiru website and downloaded the installation? manual for the 4 cylinder and 6 cylinder engines and they are saying minimum 2 psi and maximum 5 psi. This comes directly from the manual at the link below and I would not use anything but the engine manufacturers specifications

I cant seem to find any info regarding how much min. and max. and GPH my 22A2895 Jabiru 2200 (160hrs) calls for, in the event my Jabiru mechanical fuel pump fails.

It is pretty simple I just went to the Jabiru website and downloaded the installation? manual for the 4 cylinder and 6 cylinder engines and they are saying minimum 2 psi and maximum 5 psi. This comes directly from the manual at the link below and I would not use anything but the engine manufacturers specifications

Re: X Air Hawk fuel tank 'shedding' particles into fuel

do you guys think technically - if the fuel pump is about 40 inches before the carburetor, the PSI output pressure will decrease slightly from 4.5 to about 4.25, for example?

ok perfect - so my current 3-4.5 psi set up works - great to know.

I'll just replace the current pump with the exact make and model, or if there are stock shortages near my location, ill find something with a max of 4.5psi

Hello again Gents,

I cannot find any information regarding the GPH (gallons per hour) or PSI min. & max. for our electric fuel pumps.???? this will be in the requirements from the engine manufacturer, it will stipulate a minimum and a maximum psi for the fuel supply so this is nothing to do with the aircraft but is unique to individual engines

After a frustrating 20 minutes, I was able to remove the fiberglass belly pan of the X Air H. I am glad I did this because the previous owner didnt install the bypass fuel line section with a 1-way check valve! Why do you think he did not do this? ignorance or trying to keep costs as low as possible??? He built the airplane pretty well with upgraded wiring and other parts, but maybe because he felt more connections means greater potential for leaks?????

Moreover, I notice I have a Facet Cube fuel pump - model # 40105. The specs on the Cube 40105 are: 30GPH, 3.0 min PSI and 4.5 max PSI.????? a quick Google search led me to the Jabiru manufacturers website where it states the maximum pressure should be 3 psi please this is just a Google search please look at the manufacturers manual and specifications for their product

Re: X Air Hawk fuel tank 'shedding' particles into fuel

 

The jabiru 2200 uses a bing 54 carb. The nominal pressure for them is 1-4 psi. They need to be fed, but anything over 4 psi can cause the carb to flood.
he probably didn’t install the facet filter because they aren’t serviceable and was relying on the main filter.
The bypass isn’t always a well known thing and more of a work around to avoid failure. Theoretically the facet pump should allow flow through. Just sucks to find out that one time it won’t or that it’s causing a bit to much restriction when it’s not running.

Anyone have a diagram of what setup I should have ? I'll? dismantle the floor tomorrow and remove and replace the facet pump filter but then also try and plumb? fuel lines to bypass this pump, in the event it may fail.

the large gold part at the bottom of this picture is the filter. If you break them open there is a wire mesh filter in their but they are not serviceable, the only way to try and service them is to flush them backwards but I have had mixed results. The fibreglass of the X-Air fuel tank will clog these in record time so you are best to discard this filter and use a serviceable filter which is clear like in the 2nd photograph.....?? you can get these in quarter-inch, 5/16 and 3/8 nipple size and it is important to get the correct one for your fuel hose because a loose one is not a good fit

Mine has a bypass made with a one-way check valve that t's around the pump. It has a small silver filter before the pump and another filer between the tank and the filter pump. I'm not aware of any internal filter and it's not been a problems as of yet for me.
