You obviously know the implications and what it means if the wastegate is intermittant, I have seen low time pilot not realise he was down on power when the turbocharged
engine only made 29 inches on ground check.

Agreed, but the difference is that when a candidate is presented to CASA who fulfils the regulatory requirements they are obliged to approve them.
CASA hands are tied until they have prima facia evidence of the infringement - and happy I am for that or else I would have lost my licence on more than one occasion.
