McCauley A-20072, Washer, Thrust, Flyweight Assembly - Tempest PMA
Tempest AGA-20072-PMA
The Tempest AGA-20072 (McCauley OEM A-20072) is an FAA-PMA replacement washer, thrust, flyweight assembly for McCauley applications.
- Supports smooth flyweight motion by providing the correct thrust surface where the flyweight assembly reacts axial loads during operation.
- Helps maintain consistent governing response by reducing friction and wear in the flyweight stack, especially after high-time service.
- Common overhaul replacement when inspection finds scoring, fretting, heat discoloration, or wear that can contribute to hunting or sluggish response.
This thrust washer is intended for aviation use in McCauley governor maintenance, overhaul, and line replacement where OEM part numbers drive accurate cross-referencing and procurement.
Installation notes
Always consult the applicable maintenance manual for the full installation procedure before performing this work.
- Inspect mating flyweight components and contact surfaces for matched wear and replace as required by the approved overhaul data.
- Maintain strict cleanliness during assembly to prevent contamination-related wear and inconsistent flyweight motion.
Applications and fitment
Used on McCauley propeller governor assemblies where OEM A-20072 is specified. Confirm compatibility by matching the OEM part number and reviewing governor model and serial number applicability in the approved maintenance data.
Tempest AGA-20072 is the direct replacement for OEM A-20072. Match the OEM part number and confirm applicability by governor model and serial number in the approved maintenance data.
