was written black and white in the techlog: « expect soap burning smell due to low compressor wash ». For him, it does not matter he made the right decision as burning smell is no joke. But I tend to disagree in that particular case as the crew has been warned in the techlog that unusual smell might happen and it should be just of questions of minutes that the bad smell would disappear.
The flip side of this of course is that it could also be one hole in the swiss cheese, from the hypothetical report:
The pilots initially ignored a burning smell from wiring damaged by recent maintenance because of note to expect a burning smell in tech log.
I would totally agree that that the above is unlikely but then again so are most accidents.
