Perhaps we could have your perspective on the Aircraft Captain asking the Groundcrew to "have a look" at the avionics without indicating any unservicability in the Form 700 or raising any Incident Report?
Of course, because no paperwork was raised by the Captain - there was no record of any "remedial" action taken; and no confirmation by a SNCO that all necessary safety checks had been carried out and the aircraft was servicable.
We don't know if what was looked at was what the Captain meant:- so we don't even know if the fault the Captain meant was not the "fault fixed" but the fault that caused the crash!!
Perhaps you would care to comment?
