Garwin 34-828-13, Return Lever Spring - Tempest PMA
Tempest AG34-828-13-PMA
The Tempest AG34-828-13 (Garwin OEM 34-828-13) is an FAA-PMA replacement return lever spring for Garwin applications.
- Supports stable governor response by maintaining the intended spring load and lever return characteristics specified for the Garwin 34-828 series.
- Helps address issues tied to weak or inconsistent return action that can show up as sluggish control feel or difficulty holding a set RPM.
- Intended for legacy Garwin governor configurations where correct spring rate and fit are essential to proper control geometry.
This spring is commonly encountered in aviation maintenance and overhaul of older Garwin governor installations where OEM part number matching is the fastest way to confirm the correct replacement.
Installation notes
Always refer to the applicable aircraft and governor maintenance manual for complete installation procedures.
- Inspect the return lever, pins, and contact surfaces for wear that can prematurely fatigue springs or change lever geometry.
- Replace springs that show corrosion, deformation, or loss of tension, and confirm correct installation orientation.
- After installation, perform the functional checks specified in the maintenance manual to verify correct response.
Applications and fitment
This part is applicable aircraft where 34-828 series Garwin reciprocating engine speed governors are installed. Confirm by matching OEM 34-828-13 and validating governor model and approved aircraft data.
Tempest AG34-828-13 is the direct replacement for OEM 34-828-13. Search by the OEM number first, then confirm applicability by governor model and the approved maintenance documentation.
