The non reporting of the previous radalt faults may also have a partial contribution to this crash
There was
no non-reporting. Is anyone suggesting that THY crew were interviewed after the event and said 'Oh yeah, we remember the RADALT glitching but we were in a hurry to get home and didn't write it up'. Of course not. RADALTs, by their very nature, do un-lock now and again.
The fault on previous flights (and this) was only seen after the FDR was analysed.
