This is a regular discussion topic and its clear that whilst some of us would like to see some action over this issue, there are some would clearly not!!
AWN47 is full of good stuff but is written in normal CAA parlance (ie suitably vague)
Sure, we can all currently quote it to our employers until we're blue in the face! However, there's nothing in it to totally prevent anyone working Ghosters etc or any other daft amount of hours because its left up to the individual to decide how capable they are of continuing after working excessive hours.
AWN47 mentions that by law engineers are expected to take a professional attitude with reference to fitness for work etc. All this means is that if there is an incident we can be prosecuted for not following CAA guidelines . We have no legislated protection regarding maximum working hours and its this that needs resolving to level the playing field for everyone across the industry.
I think if some of the punters knew how long Engineers had been on the clock when recovering AOG’s, they would justifiably refuse to fly on the plane!
