"Oversight" can only be maintained by the HUMS being downloaded within every 3 hours of TOTAL running time, airborne and non-airborne. However I don't believe that we should be flying again until the emlube is made not only 100% reliable, which it is, but that the problem of false warning of emlube failure gets convincingly sorted out.
IMHO the present shaft has to be replaced with the older type which used different processes and techniques to join the bevel gear to the shaft. That will obviously take a long time to achieve. The French told our bosses that it can't be done, but I don't understand why. It has to be done!
With these provisos, I'll feel comfortable to fly again while a replacement for the existing shaft is being produced and tested. However our passengers will understandably need a lot of convincing.
