An official factory Service Notification been issued today on the subject of Information on the usage of Ethanol blended fuel. It provides specific directions to follow if you are using or have used Ethanol blended fuel. Much of what is stated duplicates the earlier Ethanol notice posted here in the FDUSA Owners section but it is formalized and now has recommendations that must be followed.

The Service Notification is in a new format that is soon to be described in detail on the maintenance support page. The format may look familiar to those of you who have seen the revised Rotax notices for the 912S engines. The idea is to make it easier for an owner or repairman to make certain that a specific model of Flight Design aircraft is in compliance with the factory maintenance and airworthiness notices. It may look a little confusing at first glance, but it is really quite simple. If you own a CTsw you will only need to look at notices for the CTsw and not notices for the original CT and older CT2K.

We will be updating the older notices to the new format and removing some that are no longer needed in the near future.
