BACK TO THE ROOT CAUSE...
Dear gulliBell,
Let's go back to the right tree. How can you explain the attached images of the Servo Actuator's pistons? How long do you believe the Plasma Flakes has been in C3 port? How do you explain that some of the plasma flakes have gone through the C3 port?
Just memorizing you..,.. you should be familiar with the following text:
“As indicated, we are aware of only four totalinstances of the defined failure mode. The summary of these pistons is asfollows (please note the first item listed was NOT chipped, however, it wasre-plasma sprayed in the same overhaul lot of 29 pieces that the second and thirdlisted items were also a part of – this is listed to show that we do no necessarilyhave an obvious lot problem – however,we may have a process related failure mode):”
These 29 reworked pistons went to the market 2003, with loss of Piston’s S/N because the original S/N of Piston was over coated by the plasma spray. This may be the reason why SIK can’t anymore identify and locate where these “failure mode piston are installed today”.
