Robinson Helicopter Company KI-206-3 Auxilliary Fuel Pump KI-206-4 Due to continued supply shortages and spotty availability, Rotorcorp recently checked on availabilty of the KI-206-4 Auxillary Fuel Pump for use in ENG aircraft on a customer order. We were advised by our Customer Service Representative that the shielded KI-206-4 is now being replaced by the non-shielded KI-206-3 version of the pump.

Robinson Technical Service Representative Chris Sennet confirmed that the drastically reduced noise in the new design pump motor eliminates the need for a sheilded version and that all R44 ENG aircraft should now utilize the KI-206-3. He stated that there was no documentation supporting this part reassignment.

Rotorcorp currently has three of the KI-206-3 in stock, but no word from Robinson about when thier factory supply will catch up with the current 3-4 week back order.
