SERVICE BULLETIN SB-SECS-CT__-02, SB-SECS-CT2k-03, SB-SECS-CTSW-04 Revision 01 Flight Design GmbH Sielminger Str. 51 D-70771 L.-Echterdingen Tel +49 (0)711 90287-0 Fax +49 (0)711 90287-99 E-Mail: airworthiness@flightdesign.com Date of Initial Publication: 08-Jun-2009 Publication Date of this Revision: 06-May-2010 PZ28006003_01 Page 5 of 8 © Flight Design GmbH 2.5 Avoidance of Ethanol Blended Fuel Until this SB is completed the following must be complied with. To ensure this it is the obligation of the aircraft owner to properly inform all pilots about this requirement. 1. It is highly recommended to only use fuel mixed with a maximum of 1% Ethanol content, such as 100LL AVGAS. In some countries so-called ethanol free MOGAS is available as an alternative. Refer to the Rotax Operation manual and request confirmation on the ethanol content from the gas station operator. 2. When it is the intention to directly burn the fuel during a longer flight operation Ethanol blended fuel can be used. The limitations imposed by the engine manufacturer (refer to your applicable engine operation manual) must be obeyed. 3. When the aircraft is planned to be on the ground for longer than 2 weeks, all fuel with an Ethanol mix must be drained from the aircraft. Warning: The total amount of fuel onboard does not change the storage requirements for Ethanol mixed fuel. Even when the amount of remaining fuel is small, if it has Ethanol content higher than 1% it must be drained prior to a longer down time of the aircraft. 4. When the aircraft was sitting on the ground for a longer period than specified in 3 above with Ethanol blended fuel on board, Inspection as described under Chapter 2.4 Point 2 must be repeated. 2.6 Exchange of Fuel Filter Refer to the maintenance manual for the procedure for exchanging of the fuel filter. The installed fuel filter with plastic housing must be exchanged with the new Flight Design fuel filter KF28000033. Warning: When installing the fuel filter make sure that the direction of flow is considered correct, as engraved to the fuel filter housing. In cases where you also have to install the stainless steel fuel line, the installation is illustrated in the following drawing excerpt. Take care that the hose is properly clamped with a regular hose clamp (pos. 32). Depending on the type filter being replaced, larger hose clamps may be required. Note flow direction SERVICE BULLETIN SB-SECS-CT__-02, SB-SECS-CT2k-03, SB-SECS-CTSW-04 Revision 01 Flight Design GmbH Sielminger Str. 51 D-70771 L.-Echterdingen Tel +49 (0)711 90287-0 Fax +49 (0)711 90287-99 E-Mail: airworthiness@flightdesign.com Date of Initial Publication: 08-Jun-2009 Publication Date of this Revision: 06-May-2010 PZ28006003_01 Page 6 of 8 © Flight Design GmbH Once the fuel filter has been exchanged the aircraft can be operated again within the fuel grade limitations defined by the Aircraft Operation Manual and the Engine Operation Manual. Warning: Also when the SB has been complied with, in the own interest of safe operation the information provided by SN-SECS-CT__-07, SN-SECS-CT2k- 09, SN-SECS-CTSW-05 shall be considered. The information posted in these Notifications is of general nature and applies to aircraft operation regardless of the aircraft type, model, system or its components. Once the fuel filter is exchanged, complete the feedback template and send it to Flight Design, or to your applicable Flight Design local distributor. This SB is only considered to be complied with when this feedback template has been received. 2.7 Maintenance of New Fuel Filter Maintenance intervals of the new fuel filter are as required by your maintenance manual for the initial fuel filter with plastic housing. If your aircraft has not operated before with Ethanol mixed fuel, you must inspect and clean the filter at 25 hours to remove any potential contamination from the cleaning affect that Ethanol mixed fuel can produce.

Make sure you drain all fuel in the line behind the fuel shutoff valve, before you remove the fuel filter. Insert a rag or paper towels below the filter to collect potential fuel spillage. The fuel filter can be easily unscrewed and opened using two 19mm flat wrenches. This reveals the metal mesh inside the downstream half of the fuel filter housing. Inspect the filter mesh and remove any possible dirt. Refer to the aircraft maintenance manual if dirt is found at this location. Inspect the two O-rings and exchange against new O-rings of ethanol resistant Viton, when damaged. Assemble the filter and tighten carefully until the two housing parts just get contact at the separation line. Re-attach the fuel line where it has been disconnected and carefully tighten the hose clamp. Check for leaks before returning the aircraft into service. 3 Appendix 3.1 Changes to Previous Revision Superseded document is added filter mesh O-ring 21mm x 1.5mm O-ring 23mm x 2.5mm SERVICE BULLETIN SB-SECS-CT__-02, SB-SECS-CT2k-03, SB-SECS-CTSW-04 Revision 01 Flight Design GmbH Sielminger Str. 51 D-70771 L.-Echterdingen Tel +49 (0)711 90287-0 Fax +49 (0)711 90287-99 E-Mail: airworthiness@flightdesign.com Date of Initial Publication: 08-Jun-2009 Publication Date of this Revision: 06-May-2010 PZ28006003_01 Page 8 of 8 © Flight Design GmbH 3.2 Feedback Template Flight Design This form has to be used to coordinate with Flight Design the required spare parts and to communicate the completion of the SB listed in the header of this page.
