Having opened a pandoras box by suggesting DIY pilot/owner maintenance, the nightmare of someone totally non-tech trying to service an aeroplane comes up.
EASA has not yet properly defined pilot/owner maintenance competance, and that surely needs to be sorted soon. My thoughts are that someone with an engineering qualification, or with proven technical skills would be suitable. Perhaps the LAA maintenance courses would be one way to aquire the skills. As a minimum, the ability to change the brake pads/shoes on a car, and remove/replace an alternator, plus the ability to rewire an electricplug ?? Any thoughts?
