Garwin 34-828-9, Flyweight Segment - Tempest PMA
Tempest AG34-828-9-PMA
The Tempest AG34-828-9 (Garwin OEM 34-828-9) is an FAA-PMA replacement flyweight segment for Garwin applications.
- Supports accurate speed sensing by providing the correct flyweight mass and geometry needed for stable governing action.
- Helps improve RPM stability when worn or damaged flyweight parts have caused hunting, sluggish response, or inconsistent set point control.
- Often replaced during overhaul when wear, fretting, or surface damage is found on the flyweight contact or pivot areas.
Flyweight condition is a major driver of constant speed governor feel and stability in aircraft.
Installation notes
Always consult the applicable maintenance manual for the full installation procedure before performing this work.
- Inspect mating flyweight components, pins, and contact surfaces for matched wear and replace as required.
- Verify governor settings and operational checks per approved maintenance data after overhaul or replacement.
