Embraer Legacy 600/650 Water Pump Failure

Embraer Legacy 600/650 Water Pump Failure
Embraer Legacy 600/650 Water Pump Failure

The water pump assembly used on the Embraer 600/650 has a high failure rate. Consequently, an outright replacement cost of the unit approaches close to $20,000. Most “repair” vendors will have bill back costs that equal the outright purchase due to the pump head being BER.

Service Letter AR9874-38-02 allows in the field repair that specifies the pump head can be removed from the main assembly, replaced and reinstalled. This eliminates the need to replace the entire water pump assembly, saving operators significant cost.

Service Letter AR9874-38-02 affects all water systems assemblies: PN AR9874- 3D1D74/-3D3D74/-3D5D74/-3D7D74, using Water Pumps PN 71304-X (Note: “-X” refers to all dash numbers).

The work to replace the pump head component within the main assembly requires approximately 1 hour, after access to the main pump assembly.

This repair can be completed at any of the four full-service West Star Aviation facilities For more information, please contact any of the Embraer Specialists listed below. Additional detailed information is available in Service Letter available here.
