I'm guessing that the highlighted section of the Additional Evidence section reads :

'C of I' (Court of Inquiry?) followed by what looks like a mathematical division sign, and then a '%' sign. Both before the words 'mechanical failure'.

Any idea what they might refer to??

The boxes above "Acc Code No." are numbered 1 to 7; +9 and an additional box marked "Fire".

The Royal Air Force had a Statistical Branch and my research of earlier WW2 Accident Cards (different format to these later WW2 Accident Cards) indicate that these Cause Groupings (or Accident Codes) noted on Accident Cards, were used in the compilation of RAF Flying Accident Statistics.

You will note that the "Fire" box is marked with a heavy cross (the same as "OPL" [Operational] and the "Night" boxes). Therefore, according to this they are placing the primary cause of the Accident as an aircraft fire, during the "O" [Take Off] "Stage".
(Other Stages were:- M = Miscellaneous; T = Taxying; F = In Flight; L = Landing etc.)

Regarding the other words you have highlighed, "C of I:- e/o [Engineering Officer or Engineer's title/rank] "Mechanical failure".
