Transcript of P&W PT6 Rigging

A How to Guide
Fuel Control Linkage

Disconnect the FCU control arm and mark on the arm where the pick up point begins.
The power lever indirectly controls the FCU control arm via the interconnect rod
Learning Outcomes
Identify the engine controls and there use
Describe how to statically rig an engine
Read and calculate Low pitch chart
Statically Rigging a PT6
Cockpit levers
Cam box Linkage
Fuel Control Linkage
Propeller Governor Linkage
Propeller Beta System Linkage

P&W PT6 Rigging
Prop Governor Linkage
Check that the Prop control linkage is contacting the stops in both directions.
Propeller Beta Linkage
Re-Adjust the beta arm so that it sits flush in the housing. Check that the Fuel Topping Interconnect rod is contacting its stop
Adjust the the back end of the rod end for a slip fit
Cockpit Levers
Set Cockpit levers as follows:
Power Levers to Flight Idle
Propeller Lever to Feather
Condition Lever to low Idle
Cam Box Linkage
Disconnect the prop control linkage and FCU interconnect rod from the Cam Box.

Verify that the Cam Box is free to move
