Tempest AA213181-PMA
The Tempest AA213181 (Woodward OEM AA213181) is an FAA-PMA replacement speed sensor.
- Restores reliable speed sensing for governor control and synchronization functions when troubleshooting erratic signals or intermittent sync performance.
- Supports stable RPM control by providing a consistent sensor input used during setup, checks, and operational verification.
- Helps reduce repeat maintenance by replacing a critical electrical sensing component with an FAA-PMA listed alternative where required.
This sensor is commonly used in aviation constant speed propeller governor maintenance, overhaul, and line replacement where accurate sensing is essential to troubleshooting governor behavior.
Installation notes
Refer to the applicable governor and engine maintenance manual for full installation procedures, torque values, and inspection requirements.
- Use approved installation practices for routing and securing wiring to prevent chafing, connector strain, and intermittent signal conditions.
- Confirm sensor installation depth, clearance, and any required gap or setup checks per the applicable maintenance manual.
- After installation, complete the required functional checks for the governor and any synchronizing system before return to service.
