Apparently this problem is with the TPE 331-14/15, dunno which one is on the
JS-41, but the big Garrett. Those turbine seals are not lasting as they should. For once I think link did the right thing by pulling the '41s from service, especially over this period where the schedule is not too demanding, so they can get those motors inspected/fixed. As was mentioned before it seems to be a problem with the motors themselves, not link this time round. Management should still be made to walk the f$%^ing plank though.
