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.
Just out of interest, what time scale are you suggesting? 6 months, 2 years? Or until we have a similar but worse accident. I still don't think that relying on HUMS data is really the way forward as there are only two bits of data to base these critical decisions on. The Emerg Lube monitoring will also take some time to rectify as it has never been tested (until the last few months for real) on a complete system attached to an aircraft. The tone of the first ditching AAIB report indicates how incredulous this appears to be.
