Woodward 4060-525, Cover Assembly - Tempest PMA
Tempest AG4060-525-PMA
The Tempest AG4060-525 (Woodward OEM 4060-525) is an FAA-PMA replacement cover assembly for Woodward applications.
- Provides the correct cover interface for the governor body so internal components remain protected and properly positioned during operation.
- Supports leak control and consistent performance by maintaining the intended cover sealing and fastening layout used on the applicable Woodward governor model family.
- Commonly replaced when the original cover is damaged, distorted, corroded, or cannot meet overhaul dimensional checks.
Cover integrity matters in aviation constant speed propeller governing because the governor cover is part of the oil control enclosure.
Installation notes
Always consult the applicable maintenance manual for the full installation procedure before performing this work.
- Inspect the mating flange and gasket surface for nicks, corrosion, or distortion before installation.
- Use the correct cover gasket and follow the specified torque pattern to avoid cover warp and uneven compression.
- After installation, complete the functional checks required by the governor maintenance manual.
