lamanated Posted September 5, 2003 Report Share Posted September 5, 2003 was doing some balancing today, and was asked by the pilot if we had to do the track alignment as we do on the astar,by spinning the blades by a screwdriver,etc that sits on the horizontal fin.and alligning them by loosening the through bolt.I said it is done by the component shop usually,and we just receive an exchange unit on these rent a wrecks.We used a stick to check it and found the track off by 1/4 in.I alligned it and spun it and found I had to take all the weight off the pitchlink that was on it...learn something new every day...

rotormatic Posted September 15, 2003 Report Share Posted September 15, 2003 With non adjustable pitch change links, how did you adjust the blade track? Quote Link to comment Share on other sites More sharing options...
lamanated Posted September 18, 2003 Author Report Share Posted September 18, 2003 the track was off as the assy was not centered in the fork. and when you spin the blades by a tape measure, you see the track difference. Quote Link to comment Share on other sites More sharing options...
rotormatic Posted September 21, 2003 Report Share Posted September 21, 2003 Centering the tail rotor assembly in the fork is not adjusting the track of the tail rotor. When you check for blade track, you are making sure the blades are flying in the same plane of rotation. Centering the assembly makes the tail rotor concentric to the center of the output shaft. That's why you had to make a weight change. Quote Link to comment Share on other sites More sharing options...
