As reported to the FAA. Reports are unverified, and codes are left as the FAA publishes them.

What was found

(CAN) WHILE PERFORMING A FLIGHT CONTROL CHECK IT WAS FOUND THAT WITH FULL FORWARD CYCLIC INPUT THE COLLECTIVE COULD ONLY BE LIFTED 70 PERCENT OF THE WAY UP. WHEN THE COLLECTIVE WAS FORCED HIGHER UP IN TRAVEL IT WOULD IN TURN FORCE THE CYCLIC AFT. SO WITH FULL COLLECTIVE INPUT ONLY 60 PERCENT OF THE FORWARD CYCLIC MOVEMENT COULD BE ACHIEVED.
