R-44 tail rotor

[rotormatic]

A couple of years ago, robinson issued a service bulletin to modify the tail rotor on the R-44. The bulletin required a change in rigging of the tail rotor, which reduced the max left pedal blade angle. The bulletin did not mention a revision to the flight manual.
Does anyone remember a change to the flight manual that revised the performance of the helicopter due to this reduction of left pedal authority?

there may not have been any change to the RFM issued...

- it's possible the reduction may not have actually reduced the published performance. if the aircraft can still meet the low-speed performance that's published in the RFM, then a change wouldn't be required.

my guess is that they were taking the T/R away from stall?

rotormatic,

The report for the accident that prompted the change is here:

As I recall, the pitch was reduced a number of degrees and then subsequently increased a degree or two because it was found to be too great a reduction. I never heard of any flight manual changes with regard to this.

The change is in the Maintenance Manual. There is nothing to change in the Pilot's Operating Handbook.
