This is the service notice I refered to a couple of entries earlier for the RV-12 airplane. While not technically a Service Bulletin, it is still important.
Step 1: Remove tie-wraps that may be holding the VA-213 Oil Supply Hose and VA-215 Oil Return Hose together.
NOTE: Disconnecting the VA-213 Oil Supply Hose should not be necessary to comply with this Notification. Doing so will require an oil purge. See the Rotax manual for further information.
Step 2: Inspect the VA-213 Oil Supply Hose and VA-215 Oil Return Hose for interference with the firewall structure (F-1257 Rudder Pedal Channel or corner edge of the shelf) and possible damage. See Figure 1 of notice. If only the fire sleeve has been damaged by the channel the hose assembly may be returned to service by sealing the hole with high temp RTV. If the channel has worn into the oil hose the hose assembly must be replaced.
Step 3: Disconnect the VA-215 Oil Return Hose from the oil tank. Do not disconnect the VA-213 Oil Supply Hose.
Step 4: Re-Route the VA-215 Oil Return Hose between the WD-1220 Engine Mount and WD-1221 Engine Mount Standoff.
Step 5: Re-Connect the VA-215 Oil Return Hose to the oil tank.
Step 6: Tie-Wrap the VA-213 Oil Supply Hose and VA-215 Oil Return Hose together as shown in Figure 3.
Step 7: Add RTV between the VA-213 Oil Supply Hose and the cabin heat push pull cable. See Figure 3.
Step 8: Add RTV between the VA-215 Oil Return Hose and the WD-1221 Engine Mount Standoff. See Figure 4.
Step 9: Make a logbook entry showing compliance with this notification.
This completes Notification 14-06-30.
