Looks like we've had an APU failure and a MGB chip detect in the same week over here in NL, as expected the newspapers are spinning faster than a UK politician, certainly not good for PAX confidence in the S-92a albeit sounds like Cougar did everything by the book as expected.
I know that these things happen from time to time in helo operations, but here's my questions, how often are they expected to happen with the S-92a from a design perspective, what's the track record been on these alarm modes i.e do the S-92 MGBs make metal as much as the Super Pumas. From CADORS the last NL chip light appears to be from April 2008, so that's pretty good IMO. I don't recall hearing about an APU failure before.
I recall one of the reasons stated for going for the S-92a for NL was to reduce the MGB maintenance costs that were notably high with the Super Pumas that they had. Only a rumour, but I did hear it from a good source a few years ago...
