Tempest AGA-20064-PMA
The Tempest AGA-20064 (McCauley OEM A-20064) is an FAA-PMA replacement flyweight for McCauley applications.
- Supports accurate speed sensing by providing the correct flyweight mass and geometry needed for stable constant speed governing.
- Helps address RPM instability and sluggish response when worn flyweight parts create friction, looseness, or inconsistent motion.
- Direct replacement cross reference: Tempest AGA-20064 replaces OEM A-20064 for McCauley governor service.
Flyweight condition strongly influences governor stability in aircraft, where vibration and duty cycles are demanding and consistent RPM control is essential.
Installation notes
Refer to the applicable governor and engine maintenance manual for full installation procedures, torque values, and inspection requirements.
- Inspect flyweight pins, retainers, and contact surfaces for matched wear and replace as required by the overhaul manual.
- Perform approved operational checks and adjustments after assembly to verify stable RPM control and response.
Applications and fitment
Used on McCauley governors where OEM A-20064 is specified. Confirm eligibility by matching the OEM part number and reviewing governor model and serial number applicability in approved maintenance data.
