Tempest AG196405-PMA
The Tempest AG196405 (Woodward OEM 196405) is an FAA-PMA replacement flyweight for Woodward applications.
- Provides centrifugal sensing mass so the governor can respond to RPM deviations and regulate propeller blade angle through oil control.
- Supports smooth governing by maintaining correct flyweight geometry and contact behavior within the flyweight head assembly.
- Enables OEM part number based replacement during overhaul when flyweight wear, brinelling, or damage is observed.
Flyweights are fundamental to mechanical governor accuracy and stability. This component is intended for aviation propeller governor overhaul and repair workflows.
Installation notes
Always consult the applicable maintenance manual for the full installation procedure before performing this work.
- Inspect mating pins, races, and contact surfaces for scoring or brinelling when replacing flyweights.
- After assembly, verify free movement and correct stack-up per the governor maintenance manual before final closure.
Applications and fitment
Used on Woodward governor configurations where OEM 196405 is specified. Confirm compatibility by matching OEM part number and verifying governor model and serial number in the approved maintenance data.
Tempest AG196405 is the direct replacement for OEM 196405. Match the OEM part number and confirm applicability by governor model and serial number in the approved maintenance data.
