Tempest AGA-20022-PMA
The Tempest AGA-20022 (McCauley OEM A-20022) is an FAA-PMA overhaul gasket cover for McCauley applications.
- Helps prevent oil seepage at the cover joint by restoring a proper seal surface between the cover and governor body.
- Supports stable governor performance by protecting internal hydraulic integrity and reducing contamination pathways.
- Direct replacement cross reference: Tempest AGA-20022 replaces OEM A-20022 for McCauley governor service.
This gasket is commonly replaced during overhaul or any time the governor cover is removed, since gasket compression and handling can reduce reseal reliability.
