Woodward 189611, Flyweight Head Retaining Ring - Tempest PMA
Tempest AG189611-PMA
The Tempest AG189611 (Woodward OEM 189611) is an FAA-PMA replacement flyweight head retaining ring for Woodward applications.
- Maintains secure retention of flyweight head hardware so centrifugal forces can be translated into stable pilot valve movement and RPM regulation.
- Helps prevent component walk-out or misalignment that can lead to erratic governing, delayed response, or accelerated wear inside the flyweight section.
- Supports repeatable overhaul workmanship by matching the OEM part number and intended fit for the governor design family.
This retaining ring is commonly encountered in aviation constant speed propeller governor maintenance and overhaul workflows where Tempest and OEM identifiers are used to cross reference replacement components.
Installation notes
Refer to the applicable governor and engine maintenance manual for full installation procedures, torque values, and inspection requirements.
- Confirm the ring is fully seated in the groove and replace any ring that shows loss of tension, distortion, or surface damage.
- Use the governor maintenance manual procedures for disassembly and reassembly to avoid nicking precision surfaces.
Applications and fitment
Commonly associated with Woodward reciprocating engine speed governor installations. Confirm compatibility by matching OEM part number 189611 and reviewing the governor illustrated parts list and approved maintenance data for your specific governor model and aircraft.
Tempest AG189611 is the direct replacement for OEM 189611. Match the OEM part number and confirm applicability by governor model and serial number in the approved maintenance data.
