We draw all 9 series Rotax Aircraft Engine users attention to the details in the bulletins SB-912-066 / SB-914-047 and SB-912-066UL / SB-914-047UL ( and These bulletins highlight important changes for new engines (see the relevant serial numbers in the bulletins), and also in regards to those who may have changed a cylinder head on an older engine (the new Cylinder heads entered the market on engines and as spares from early 2013).

Rotax has now introduced the new cylinder head configuration as standard on new 9 series engines, but it should be noted that this type is also compatible with older engines – and the two types may co-exist on the same engine as a result of maintenance or overhaul.  However, because the temperature probe on the new configuration is no longer in the cylinder head material, but now sits in the coolant itself, there is a required change in the way we refer to and measure that temperature.  The allowable temperature range for the probe in that position, as well as the naming of the indicating instrument on your aircraft, should you have the new cylinder type on your engine may now be different.   i.e. for those with the new cylinder head configuration and probes, it is no longer ‘Cylinder Head Temperature’ that is being reported, but ‘Coolant Temperature’, this should be reflected in instrument naming.

Rotax releases SB on Fuel Floats

SB-912-065 UL_914-046 UL_english_Page_1Today Rotax released Service Bulletins SB-912-065/SB-914-046 for certified engines and SB-912-065UL/SB-914-046UL for non-certified engines. These are very important bulletins dealing with a mandatory inspection of the carburetor floats on a specific serial number range of engines.  Owners should check to see if these bulletins apply to their engines.

Here are the serial numbers affected.

All versions of the engine type:

Engine type Serial number
912 A from S/N 4 410 957
912 F from S/N 4 413 008
912 S from S/N 4 924 408
914 F from S/N 4 421 136


Also affected are all floats part no. 861184 which have been installed as spare part or during engine repair/general overhaul since 1. July 2012.

NOTE:  The affected floats were delivered with the engines listed above.

The part number and serial numbers of the carburetors:

Carburetor  type Serial number
Carburetors 912 A/F 1/3 part no. 892500 – from S/N 116434;
2/4 part no. 892505 – from S/N 115846;
Carburetors 912 S: 1/3 part no. 892530 – from S/N 121087;
2/4 part no. 892535 – from S/N 120980;
Carburetors 914 F: 1/4 part no. 892520 – from S/N 116207;
2/4 part no. 892525 – from S/N 120228;

The carburetor and/or the float may have been removed from the first delivery engine and used on another one. Therefore the serial number of the carburetor is also important as the engine serial number. For relevant information, see the maintenance records and/or the logbook.

 Questions and Answers regarding this Service Bulletin:

Q: So what is this all about?

A: Simply put, it was found that some floats may be retaining fuel and thereby increasing in weight. This is not good. It must be remembered that not all floats seem to be doing this, that is why there is a test procedure outlined in the Service Bulletin. Also, at this point in time, it is not known what is causing this retention and there is no simple replacement fix, that is why there is a request that this inspection happen every 25 hours of flight or 60 hours total time, until a solution for this is found.

Q: Who is authorized by the factory to perform this work?

A: Rotax requires an independent Rotax Maintenance Technician (iRMT) with a current Maintenance or Higher rating. You can find these in the US, Central or South America by going to

Q: All this seems really complicated.

A: It may seem a little overwhelming at first, but Rotax has done a really good job of explaining the testing procedure in the bulletin. If you are still not sure, please contact your closest independent Service Centre or iSC. They will be more than happy to give you all the details.

Here is a list:

BRAZIL Cruzeiro do Sul Aviação

If you are outside the above areas, please go to and find the service centre in your region.

Q: Why are there three types of warranty claims?

A: Well, technically there are only two. The first inspection covers the tooling you need to perform the inspection. Then every other inspection after that is considered without tooling as it was already supplied. Why the need for extra claim types depends on whether or not the floats needed to be changed. Again see your iSC to assist you with this.

912iSSport*UPDATE: Rotax released SB-912i-003iS R1

Ok with all the news, hype and speculation out there – we wanted to get to the bottom of it all.  Just the facts!

The most important thing to remember in all of this, is that the 912 iS Sport Kit (the KIT) is a must choice for any current 912 iS owner.  According to John McBean of Kitfox Aircraft (John was the first person in the US to install and test fly the Sport Kit upgrade) found that he upgrade produces a much better torque curve than the current iS engine.  He even noted that he was keeping up with a 914 Turbo during the flying tests.  Add in the fact that Rotax is providing the KITS free of charge (parts only) to all current owners (for a limited time) this is a no brainer choice.

So with that being said, is it an easy installation?  No, it is not.  This is not a simple bolt on and go procedure.  Technically it should take between 8 – 12 hours for a current  Heavy Maintenance rated independent ROTAX Maintenance Technician (iRMT) to perform the swap.    Also bear in mind that there is an stronger clutch in the KIT as well to handle the additional torque, so that means the gearbox has to come apart.   There are a few other things to factor in, so here is a quick overview:

  • First – ASTM COMPLIANCE must be considered.  I hate wordy things but here goes:  This is for all owners to consider, but especially important to owners of  SLSA aircraft where ASTM compliance is required by the regulator and the standards.  As soon as you modify the engine, it is no longer ASTM compliant. That in turn means the aircraft cannot be flown legally.  Fortunately this can be solved by doing  some verification tests prior to and after installation of the kit.  Click here for a the compliance verification form.
  • Second, because the engine will no longer be a 912iS, but a 912iS Sport, the engine serial number plate will have to change.  A new plate (same serial number) is provided with the kit – but it must be ordered ahead of time so that it can be added to the kit before it is sent to the iRMT that is doing the installation.
  • Third, your current electronic control unit (ECU) will need to be returned for a software upgrade.  Yeah this is a bit of a hassle, but if you time it with the installation of the kit (step 4) it will not be that much of an inconvenience.
  • Fourthly, the actual KIT needs to be installed.  This job can only be performed by an iRMT that has a current 912 HEAVY MAINTENANCE RATING.  (see for listings.)
  • Fifthly (lol – rarely ever say that word) – all the old parts have to be returned to your local independent Service Centre (iSC).
  • Lastly, for you SLSA owners, a new ASTM compliance check and application must be submitted.  Rotax can then issue a new compliance statement if required.

This seems to be a lot of steps – and there are – but remember the first paragraph – it is worth it.  Thankfully you are in good hands.  Contact your local  (iSC) and they will go over all these details, help you find a technician and schedule an appointment for you.  Rotax does have an amazing support network.

It is important to note that with the release of the new engines and kits. there are new manuals.  You can find a copy of these on or

AERO 2014: A Strong Showing for General Aviation in Friedrichshafen

AERO 2013Friedrichshafen – The countdown is on: with some 600 exhibitors and even more enhancements, AERO 2014 will strengthen its position as Europe’s largest trade fair for general aviation. From ultralights to multi-engine business jets, from helicopters to gyrocopters, the full spectrum will be featured in Friedrichshafen. Highlights include the “e?flight expo” with electrically propelled aircraft, the “Engine Area” dedicated exhibition, and the “Avionics Avenue” specialty zone. Drones for civilian use will also attract plenty of interest. Here, the trade fair team will turn the spotlight on the “UAS/RPAS Expo” (Unmanned Aerial Systems), a joint exhibition at AERO that focuses on these new devices.

Messe Friedrichshafen CEO Klaus Wellmann and AERO project leader Roland Bosch are very pleased AERO 2014 has already seen brisk bookings for exhibition space. General aviation includes all civilian, non-military aircraft, except for commercial airliners. According to EU figures, over 200,000 powered aircraft, ultralights and gliders are registered within the territory of the European Union alone. Once again, this international trade fair on Lake Constance will cover the wide spectrum of this sector almost completely. “AERO is Europe’s leading trade fair in this sector,” says Roland Bosch, who is certain that every top manufacturer will be represented once more in Friedrichshafen.

Four special spotlight zones will be featured at AERO 2014. The “e?flight expo” is the longest running one, now taking place for the sixth time, showcasing alternative propulsion systems under the motto “Electrical, Ecological, Evolutionary”. The “e?flight expo” may get an extra thrust from the scheduled first appearance of the revolutionary Volocoptor, made by the e-Volo company of Karlsruhe. While a model of this electrically driven 18-rotor helicopter was exhibited at AERO in 2013, the Volocopter prototype will be featured in 2014, if permitted by flight trials this spring. This futuristic rotorcraft had its first flight in November 2013, attracting great attention.

Surprise Sun ‘n Fun Showing by Kitfox Aircraft

Homedale, Idaho, March 18, 2014.  Earlier this year, Kitfox Aircraft LLC announced that the company would not be able to participate in the big air shows of early 2014.  It seems that success had created a backlog of orders that simply took priority over trade show attendance.  According to John McBean, President of Kitfox Aircraft, “We received a call from the U.S. distributor for Rotax® engines with an offer we just couldn’t refuse.”  Mr. McBean continued, “They asked if we could display our newest Kitfox S7 Super Sport at the independent Rotax® Service and Training Centre booth (SE-014 at the main entrance) at Sun ‘n Fun this year, as a means of demonstrating the long time support Rotax® has provided to both the kit plane and S-LSA end of the light aircraft market.  As one of the most experienced users of the Rotax 9 series engines and manufacturer of both kit and S-LSA airframes using the Rotax® engines, we were honored to be selected as the company to represent Rotax® use in recreational aircraft.”

Mr. McBean is expected to leave his Idaho factory location on March 25, allowing time for meetings with Rotax® staff and a briefing on important announcements that are expected from the Rotax® side of the house.  When asked about the production issues, John responded, “Should I consider it a compliment if my team says they can do just fine without me at the plant?  Seriously, we have taken a good look at the production line and this trip will not impact deliveries.  The opportunity to support our good friends at Rotax® is just too good to pass up.  We hope that Kitfox enthusiast will stop by and say hello.  We may have some surprises to announce and I look forward to greeting folks in person.”
