We have published Safety Directive SD-00017, which applies only to the original/legacy RV-12 (it does not apply to the RV-12iS).
This Safety Directive requires inspection before further flight of the fuel flow return line to ensure fuel is actually flowing through the return. This is a simple and quick check and can be accomplished by the owner/operator in about 5 minutes. No tools or parts are required and there is nothing you need to order to conduct the inspection.
In the event the return line is found to be blocked, the document contains the mandatory additional steps to rectify the issue.

Context: A blocked return line fitting was discovered on one RV-12 in the field. Due to the potential risk and impact of a fuel flow issue, we have issued this as a before-further-flight notice. Performing the check of this critical system is a quick and simple process.
