McCauley A-20184, Solid Pivot Unfeathering Pin - Tempest PMA
Tempest AGA-20184-PMA
The Tempest AGA-20184 (McCauley OEM A-20184) is an FAA-PMA replacement solid pivot unfeathering pin for McCauley applications.
- Supports dependable unfeather function by restoring a tight, correctly fitted pivot point where wear can create looseness and inconsistent motion.
- Helps reduce binding and abnormal wear when a worn pin has created misalignment at the unfeather pivot interface.
- Common overhaul replacement because pivot pins experience cyclic loading and can develop wear patterns that affect mechanism feel.
This pivot pin is intended for aviation propeller governor maintenance and overhaul where OEM part numbers are the primary way technicians validate fitment.
