Not to impressed with the no fuzz burn aspect. This will make a difference in the "emergency Procedure" for a chip. I would certainly like to know if the light is just fuzz or perhaps something bigger.
Also do not like the daily chip plug / filter inspection.
But that is just my opinion.
Generation of nuisance debris (or fuzz) is common with new components like gears/bearings/splined shafts that have not been run much. Fine ferrous metal debris generated by a gearbox with some hours on it, and picked up by magnetic chip detectors, is often an indication of early stage spalling failure of a bearing or gear. This type of failure typically progresses at a fairly slow rate, and does not usually present an immediate hazard to continued operation of the aircraft.
Inspecting chip detectors and the oil filter every 10 hours will require a lot of man hours. It is common to replace o-rings and fasteners every time these components are re-installed. Larger pieces of debris usually do not make it to the oil filter, since there are wire mesh screens located at the oil pump pickups.
