idle and 100% test and 25hrs
Thanks!
First, the hydr test in idle is ok. 100% fails (collective will not be able to move fully down from approx 80% RRPM and up).
We were thinking about servo, and replaced actuator but re/check!
Work during inspection only on tailrotor. It seems to becomming worse every week....
We checked and-or replaced
Inspection revealed minor leakage on Collective Servo Actuator (212-076-005-111). New (o´hauled) actuator was installed.
Collective Control Rigging performed. Minor adjustment needed.
Replaced Balance Spring. Checked and measured, within limits.
Performed Groundrun with Mast Boot removed.
Checked Hub and Sleeve Assy.
Replaced Shim between Hub and Drive Plate set. New Shim showed 0,4 mm thicker.
Replaced Drive Plate set.
Checked Collective Lever for axial play.
Checked Cyclic Control rigging.
Checked all Elastomeric Bearings.
Checked Droop Compensator Cable for smootheness of operation. Replaced Nut and Bolt of Droop Compensator to Cable.
Checked Collective Engine Throttle System for binding.
Checked all Collective Control System for binding.
Many thanks for all the kind reply!
Best regards,
Ed
