Tempest AGB-20769-PMA
The Tempest AGB-20769 (McCauley OEM A-20769) is an FAA-PMA replacement flyweight for McCauley applications.
- Supports accurate RPM sensing by providing the correct flyweight mass and geometry so centrifugal force changes are transmitted consistently.
- Helps reduce instability and uneven response when worn flyweights develop loose pivots, scoring, or contact surface damage.
- Common overhaul replacement when inspection finds abnormal wear patterns, corrosion, or out of tolerance conditions that affect balance and movement.
Flyweights are the heart of many mechanical governor designs in aviation, and their condition directly impacts response feel and RPM stability.
Installation notes
Refer to your aircraft and governor maintenance manual for complete installation procedures and torque values.
- Inspect flyweight pins, retainers, and mating surfaces for wear and replace as required by approved overhaul data.
- Confirm smooth, free movement of the flyweight assembly after installation and complete the required operational checks.
Applications and fitment
Used on McCauley governor assemblies where OEM A-20769 is specified. Confirm compatibility by matching the OEM part number and reviewing governor model and serial number applicability in approved maintenance data.
Tempest AGB-20769 is the direct replacement for OEM A-20769. Match the OEM part number and confirm applicability by governor model and serial number in the approved maintenance data.
