Woodward 1039-268, Lever Clamp Screw - Tempest PMA
Tempest AG1039-268-PMA
The Tempest AG1039-268 (Woodward OEM 1039-268) is an FAA-PMA replacement lever clamp screw for Woodward applications.
- Maintains positive lever clamping to help prevent lever slip that can cause inconsistent RPM setpoint, droop, or difficulty holding selected propeller speed.
- Supports reliable rigging by matching the Woodward form, fit, and function for the lever clamp interface used on many legacy governor installations.
- Helps resist vibration-related loosening when installed with the correct clamp hardware and torque procedure per approved maintenance data.
This screw is intended for aircraft constant speed propeller governor maintenance and overhaul workflows where technicians cross reference Tempest and OEM part numbers for replacement components.
Installation notes
Always refer to the applicable aircraft and governor maintenance manual for complete installation procedures.
- Confirm lever clamp orientation, mating surfaces, and clamp hardware condition before installation. A worn clamp or fretted shaft surface can prevent proper clamp load even with correct torque.
- Apply the torque value and any locking method specified in the Woodward governor maintenance manual or approved data for the specific governor model.
- After installation, perform a rigging and functional check to confirm full lever travel and stable RPM response.
Applications and fitment
Used on Woodward propeller governor installations, including applications where Woodward model A210800 reciprocating engine speed governors are installed. Applicable for multiple Beechcraft models in this family (for example Bonanza 95-C55 and Baron 58 series) where the Woodward A210800 governor is installed.
| Aircraft | Propeller Governor Model |
|---|---|
| Beechcraft Bonanza 95-C55 / 55A / D55 / E55 | Where Woodward A210800 reciprocating engine speed governors are installed |
| Beechcraft Baron 58 / 58A / 58P / 58TC | Where Woodward A210800 reciprocating engine speed governors are installed |
Confirm compatibility by matching the OEM part number and reviewing the governor illustrated parts catalog and maintenance instructions for your specific propeller governor and aircraft installation.
Tempest AG1039-268 is the direct replacement for OEM 1039-268. If you are searching by alternate identifiers (such as AN hardware cross references), confirm applicability by governor model, lever clamp configuration, and the approved maintenance data for your installation.
