8-15 from Odiham
Civil engineers at Northolt - very hot on paperwork (It justified the overtime).
Sorry, couldn't resist that.
The point is quite simple; Tapper & Cook did not formerly raise any defects after the first sortie, but we know that work was carried out by Avionics Tradesmen at their request. Was any other work carried out that we do not know about? If there was - could it have a bearing on the crash?
This is only an issue because Tapper and Cook requested investigation into an avionics problem without raising the appropriate paperwork. If they had formerly placed the item unservicable then there would have been an identifiable chain of investigation and rectification to cure the fault. It is possible that other work we know nothing about was also carried out and that such work could have a bearing on the accident.
