SEP aircraft defects not logged
My flying school follows a process whereby any aircraft defect is written down on a scrap piece of paper and then passed to the engineer for action (i.e. AH not level, radial discrepancies between two VOR's tuned to same VOR, wingtip strobes not working etc); the aircraft's logbook just records a 'NIL' entry against observed defects. I thought that defects should be raised in the aircraft's logbook so pilots can see the defects which have occurred and the action taken to resolve the defect or to label it as an acceptable defect ftb. Hence we have logbooks for some aircraft with no defects recorded whilst other aircraft have i.e. only one defect formally recorded say every 6 months.
Given the aviation industry is highly regulated, I would have thought more formal recording of defects should be in place. However, I'm no expert in this matter so would welcome some advice. Does the CAA have any material to define the type of defects which should be formally recorded?
It just worries me that as a PPL I could be flying aircraft with defects for which I'm not aware.
